Here are the various focal plane cameras in my collection. Note that SLR cameras, most have which have focal plane shutter, have their own page.
Other groups that can be found on other pages:
Most cameras on this site had leaf shutters, like the various Compurs and Prontors, which were usually mounted between the lens elements or, in case of interchangeable lens mounts, just behind the lens. As the name indicates, leaf shutters are build of 2 or more leafs, which rotate away and back when the shutter fires.
Leica IIIa, IIIc, IIIf
Another type of shutter was the focal plane shutter, usually mounted just in front of the film plane. It consisted of a moving piece of cloth, commonly called the curtain, with a gap that allowed light to reach the film. The shutter speed increases with the width of the gap, or, in case of longer shutter speeds, the time difference between the opening and closing curtains.
The advantage of the focal plane shutter was that it was relatively easy to reach higher shutter speeds like 1/1000 second. The drawback is that with speeds faster than ca. 1/30 s, the film is not exposed as a whole, so fast-moving objects can cause problems. Also, flash sync speeds were slow.
The most famous member of the focal plane shutter cameras is undoubtedly the Leica, plus all its various copies. Other ones are the Exakta range, the Finetta 99, the Foth Derby and the Contax/Kiev range. Examples of the Exakta, Contax and Finetta are detailed elsewhere on this site, so only the Leica features below.
Many books have been written about the Leitz company and its cameras and lenses, and there is little point in repeating much here. Leitz invented the 35mm camera (Leica A) in the 1920s as a small and convenient alternative to the larger box, folding and TLR rollfilm cameras. Soon after Leitz developed the interchangeable lens mount, which allowed the use of different lenses as well as various accessories for macrophotography, copying etc. The increasing popularity of the 35mm format led Kodak to invent the 135 film cartridge, which quickly became the dominant film format for the next 70 years and undoubtedly helped the popularity of the Leicas also.
Leicas have always been expensive, top-of-the-range cameras and are even more so these days, now that Leitz seems to focus more on exclusive collector's items than cameras that are meant to be used. Prices have more to do with collectability than anything else and are much inflated over what they used to cost compared to other cameras at the time. From that perspective Leicas are an excellent investment, but expect to pay through the nose for the simplest accessories!
The Leica III series was introduced in 1933 and featured a 39mm screw mount (a.k.a. LTM or L39 mount), a rangefinder with 1.5x magnification and separate viewfinder plus a slow speed dial at the front of the camera in addition to the regular speed dial on top. The Leica II series lack the slow speed option, whereas the Leica I series had no rangefinder. For all lenses other than the standard one one would need separate viewfinders.
A 1935 Leica IIIa (ser. 183196) with uncoated Leitz Elmar 50mm f/3.5 collapsible lens. The flash sync must have been a later addition but has been very professionally done. There is no flash synchroniser dial like on the later Leica IIIf, so I suspect the flash only synchronises at very slow speeds of about 1/20s in which case the shutter curtains are far enough apart to expose to whole film at once. This was a drawback of focal plane shutters compared to leaf shutters, which would sync at all speeds.
The Leica IIIc was the first with a diecast body, which made the body more rigid, and had an integrated top housing with rangefinder cover as well as better shielding around the film gate which reduced fogging of film left in the camera for longer periods of time. Another change was the rangefinder magnifier, which was moved from behind the eye piece to beneath the rewind knob. Furthermore the 1/30s speed moved to the slow speed dial.
A 1947 Leica IIIc with Leitz Summitar 50mm f/2 lens. A somewhat disappointing aspect of using screwmount Leicas up till the IIIg was the underwhelming viewfinder. However, Leica did, however, produce a separate 50mm viewfinder, named SBOOI, and this is simply the best viewfinder I have ever used. Its view exactly 1:1 so one can keep both eyes open whilst looking through the viewfinder and see a frame projected in your field of vision. It works in near darkness and is exceptionally clear. These are not cheap but definitively worth it. The one pictured here is a later version (ca. 1958) with markings in capitals letters and focal length in mm.
Three different standard lenses were available in Leica screw mount, from left to right the f/2 Summitar, the f/2 Summar and the f3.5 Elmar (later updated to f/2.8), ignoring the f/2 Summicron which was introduced near the end of the screwmount era. Although the Elmar f/3.5 is an excellent lens, I prefer the larger aperture of the Summitar and the associated shallower depth-of-field. It is also an extremely sharp lens, it being a seven-element lens with large front element, at smaller apertures easily outresolving the 24 MP APS-C sized sensor on my DSLR camera. That said, I find the Summar the best looking lens of the three, preferring its rounded base and smaller front element over the Summitar on screwmount Leicas.
Detail of the Leica rangefinder windows and Summitar lens base taken with the Elmar mounted on a Sony A77 DSLR. As the register distance of the Sony is much larger than that of the Leica screw mount, the Leitz lenses make great macro lenses. As they can be partially collapsed the maximum focus distance is about 4 ft.
Top view of a Leica IIIc with the collapsible lens extended.
The screw-mount Leicas are bottom loading cameras and rather inconvenient to load as the film leader needs to be cut to slide properly over the sprocket wheels. Luckily Leica provided a little diagram at the bottom of the camera to remind people of this, a feature that other bottom loaders should perhaps have thought of (Iloca!).
One of the fun but frustratingly expensive things about Leicas is that there are so many accessories available. Many had funny five-letter acronyms, this close-up attachment had the unfortunate name NOOKY. It screws on the lens mount and the collapsible Elmar is then inserted, its own focussing mount still attached. It allows near-macro photographs with a maximum enlargement of 1:6.5.
The Leica IIIf was very similar to the Leica IIIc and the two were in fact hard to distinguish when viewed from the front. The main new features were a flash sync, which was located at the back of the camera next to the eye piece of the viewfinder, and a film reminder dial integrated in the wind knob. The speed dial was also slightly larger than the one on the IIIf and contained a synchro-dial to adjust the flash exposure settings.
Three different versions of the IIIf were produced in about equal numbers, the first had black synchro-dial numbers (hence called 'black dial' or BD), the second version had red numbers (i.e., red dial or RD), whereas the last version added a selftimer to the slow speed dial (hence RD ST).
The flash settings were a little idiosyncratic to say the least, but the system was designed to make high-speed flash synchronisation up to 1/1000th of a second possible. Some sources on the internet claim that the flash only worked at 1/30s, but that is only true when using electronic flash. Of course not many people use flash bulbs these days, so these sites have a point, but with the right flash bulbs high-speed synchronisation was possible.
The synchro-dial setting was dependent on the shutter speed with higher values for slower shutter speeds. The values were provided as a table which also listed the effective guide number from which the aperture setting could be calculated.
(Top) Rear view of a 1951 Leica IIIf BD showing the flash sync next to the viewfinder eye piece and the flash synchro dial beneath the speed dial. The black numbers of the synchro dial indentify this IIIf as a 'Black Dial'. Leitz provided a special flash sync plug (shown in the image) which would not poke into your eye when using the viewfinder.
(Bottom left) Detail showing the film reminder dial integrated with the wind knob. (Bottom right) The lens mounted on the camera is a red scale Elmar f/3.5, the last Elmar f/3.5 of the many incarnations produced by Leica. Earlier Elmars had the focus scale on the bottom ring and DOF scale on the barrel, so the other way around compared to the red scale Elmars.
Leica IIIf with the rather large, dedicated Leica flash unit 'Synchronblitzer' a.k.a. CEYOO, which fitted onto the camera's accessory shoe.
Here is a NOOKY close-up attachment with its original box. This one is for the Elmar, other versions were available for the Hektor, Summar and Summitar lenses (the NOOKY-HESUM) as well as the Summicron (the SOOKY).
A rather uncommon wide angle lens in Leica screw mount was the Schneider Kreuznach Xenogon 35mm f/2.8. It was introduced around 1952 at a time when the fastest Leitz 35mm lens was the f/3.5 Summaron. It was presumably intended to compete with similarly fast Canon Serenar and Nikon W-Nikkor 35mm lenses. Leitz did not introduce a f/2.8 35mm lens until 1958.
Based on the serial numbers the Xenogon was produced until about 1957. As the serial numbers cluster strongly it appears they were made in small batches of a few 100 at a time, in total probably less than 2000 were made, most of them in 1952 and 1953.
The name Xenogon was probably derived from Xenon, as it had a similar optical formula of 6 elements in 4 groups in a symmetrical configuration, just like the Seranars, W-Nikkors and Summarons of the time. Note that this lens was different from the more common Xenagon, which was a 4-element lens derived from the Xenar, and as far as I am aware not available in Leica screw mount.
No Leica collection is complete without one of the telelenses. The 90mm f/4 Elmar had the best reputation, at least in the screwmount. This is a simple lens to clean and maintain; the front part of the lens simply unscrews from the focussing tube to provide easy access to the lens elements.
By lack of the proper Leitz 90mm viewfinder I mounted one from a neighbouring company in Wetzlar, Leidolf.
A rather unusual accessory for the Leica was the Proximeter. Proximeters were available for many cameras and usually included a close-up lens to mount on the camera lens as well an additional lens in front of the rangefinder which would compensate for distance and parallax. This particular one was a large round disc that contained both lenses. I actually had no idea these were made for Leica also, as there already was the NOOKY range of close-up attachments. I had seen one of these large round ones on a King Regula, so expected it to fit to Cassar lenses. However, it did not fit any of my cameras until I, mostly out of desperation, finally tried it on the Summitar. It fitted! Then I noticed in the included instructions that Leica was indeed listed. I have not yet tried how well it works. Advantage compared to the NOOKY is that one does not need to remove and remount the lens, potential drawback is that the close-up lens may degrade image quality.
In the 1930s FED was the first company (or rather labour commune) to produce a 35 mm camera in Communist Russia. They chose their example (the Leica I!) wisely, although admittedly at that time the choice was limited. Initially based on the Leica I and II, the FED range slowly evolved into a range of increasingly different cameras. It became a hugely popular range with many million cameras produced. Many subtypes of each model existed, so a bewildering range of these cameras was available.
The first type, simply designated FED but now called Fed-1 to distinguish from later models, kept its clear Leica II heritage until the last version, the 1953 Fed-1 G. Enterprising individuals have used this similarity to convert FEDs to fake Leicas, but these are usually easy to spot due to several small design differences. That said, early FEDs may fetch prices comparable to Leicas in their own right.
A 1956 Fed-1 G (#561825) with collapsible Fed 50/3.5 lens, the latter clearly a copy of the Leitz Elmar although the optical formula was different and more similar to a Tessar design. The 'G' was the last Fed-1 model, the following Fed-2 no longer looked like the original Leica II although it would still take the same 39mm screwmount lenses.
Top view of the same camera. Compare this with the same view of the Leica IIIc above and try to spot the differences! One give-away is the collar around the shutter release, which on the FED rotates during winding the shutter.
Opening up a FED seemed more sensible than doing the same to a working Leica...
The Fed-4 was the first Fed camera with a built-in selenium light meter. Fed was rather late to do so; when the Fed-4 was introduced in 1964, German cameras had these light meters for about 10 years and in fact, selenium cells already started to be phased out in favour of CdS cells on many Japanese cameras. Even then the light meter on the Fed-4 was uncoupled, so settings had to be transferred manually to the shutter. On the other hand, Leica itself did not introduce metering until the M5 in the early 70s.
The first Fed-4 model looked a lot like the Fed-3, with a large chrome top housing and small rangefinder windows. Its most peculiar feature was the lack of rewind knob, which had made way for the light meter unit and was therefore replaced by a rewind wheel at the side of the camera. Had the wheel been larger like on the Ferrania Lince it would have been all right, but unfortunately it was cumbersome to use. Around 1969 the Fed-4 was updated with a more modern-looking viewfinder frame and a wind lever, although the rewind wheel stayed. Despite the niggles it was a well-functioning and successful camera with a long production run of about 15 years and over 1 million units being build.
Late version of the Fed-4 with amber-coated Industar-61 53mm f/2.8 lens. All Fed-4 had this model lens but quite a few different versions existed, with various focal lengths (52mm, 53mm and 55mm) and body types (chrome, zebra chrome and black, or mostly black). Later versions had the suffix L/D (in cyrillic), the L apparently referring to lanthanum, a heavy element added to glass to increase its refractive index while keeping dispersion low.
Top view of a Fed-4 showing the peculiar slanted edge of the op housing to make room for the wind lever. Note the simple uncoupled light meter on the left. Also note the range peculiar order of shutter speeds, with 1/30 in-between B and 1s. Like most Russian 'Leica copies', the shutter speed of this model can only be set after cocking the shutter and one should also not move the shutter speed dial from 1/30 to 1/s or vice versa, I drew a small line as a reminder.
The other Russian Leica copy one may come across is the Zorki. These were produced after the war, mainly for export. The first model again appeared to be based on the Leica II, but in fact it was a copy of the original FED. The FED factory had been destroyed during WWII and was having trouble getting production started after the war had finished. Therefore, production was moved to a different factory and early cameras were called Fed-Zorki. Later on the two brands diverged and produced their own camera ranges.
The Zorki 4K, first produced in 1972, was the first model with rapid wind lever and looked little like a Leica copy anymore. It came with flash sync, time delay and large viewfinder window. About half a million of these were made. Somewhat ironically, at a time when the SLR camera had made the rangefinder system camera nearly obsolete in the West, Soviet copies like the FED, Zorki and Kiev kept the tradition alive.
A Zorki 4K, which normally came with Jupiter 50mm f/2 lens but here with an older FED-branded Industar 26M lens. One drawback of most Russian Leica copies was that the shutter speed dial should only be set after the shutter was cocked, failure to do so could jam the shutter mechanism.
A Zorki 4K with top and front removed to provide access to rangefinder and shutter mechanism.
A lesser known Russian Leica copy was the 1956 GOMZ Leningrad, although calling it a Leica copy does not do it justice. It had little more in common with the original Leicas than the screw mount, and in contrast to Fed and Zorki cameras the Leningrad was designed from the ground up. Its most distinguishing feature was the spring motor, which allowed taking many photos in rapid succession. It was very well-build but expensive and heavy camera that won in fact a reward at the 1958 World Exhibition in Brussels. It was only produced in (for Russian standards) small numbers (<100,000).
Despite its new design the camera did have some features reminiscent of other cameras. It feels more like a Kiev (Contax copy) than other Russian Leica copies and in fact the bottom plate is very similar to Kiev ones. In addition, the large spring motor wind knob and speed selector are reminiscent of the Finetta 99. Also the spring motor release for rewinding film at the bottom of the camera is the same as on the Finetta. Whatever its inspiration, the Leningrad designers took this camera much further and is probably the most impressive camera to come out of the former USSR.
A GOMZ Leningrad with Jupiter 50mm f/2 lens. This example was an export model as the name Leningrad is written in Roman script, not Cyrillic. It is missing the rewind knob as well as the speed dial, which I to my shame only noticed after buying the camera.
Canon will need little introduction as it is still the largest camera maker in the world. The company was founded in the 1930 under the name Precision Optical Instruments Laboratory (POIL), it's first product being the Hanso Canon, a high-quality rangefinder largely based on the Leica II with some modifications. Interestingly, POIL lacked the expertise for making optics and therefore obtained the support from Nippon Kogaku, a company that later would turn into Nikon. So thus the first Canon had a Nikkor lens. More Canon models were soon to follow and Canon started designing its own lenses, initially branded 'Serenar'.
After WWII Canon grew rapidly as a company and introduced several new rangefinder models in the early 1950s, all of which used the Leica screw mount. However, soon after it moved towards SLR cameras, apparently after realising that following the introduction of the Leica M3, it would take too much effort to keep up with rangefinder technology. That this was a wise decision needs little explanation, considering the dominance of Canon on the camera market ever since.
A Canon II-F from around 1953 with Canon Serenar 50mm f/1.8 lens. This lens had an optical design more similar to the Steinheil Xenon and the Zeiss Biotar than to the Leitz Summitar, but had an equally good reputation. I got a bargain on this one as it had a problem with one of its inner rear elements. It turned out to be a fine mist of oil droplets, which was easy to clean and now the lens is back up to its old tricks.
Top and rear view of the Canon II-F. Compared to screw-mount Leicas it benefited from having a single rangefinder/viewfinder window with adjustable magnification for ease of focussing, as well as a film reminder dial in the wind knob. It also featured a slow speed dial, a top shutter speed of 1/500s and a flash sync rail.
Canon IIF with top housing removed, showing speed dial (left) and rangefinder unit (right). The adjustable magnification of the rangefinder functioned by rotating the small lens unit near the eye piece by 90 or 180 degrees, respectively.
Stripping the camera this far to adjust the rangefinder would be unnecessary: the large screw next to the front viewfinder window hides a horizontal adjustment screw, whereas the vertical alignment could be adjusted by unscrewing the round cover ring of the rangefinder window and rotating the thus exposed glass element (not visible in this photo as it needed to be removed to disassemble the top housing).
As an encore, a Canon II-F shown with a collapsible Canon Serenar 50mm f/3.5 lens, giving it a more classic Leica look. Clearly based on the Leitz Elmar, the Serenar lens is constructed somewhat differently, but does have the aperture directly behind the front element, which is typical of the Elmar design.
Although Canon decided after the introduction of the Leica M3 that they couldn't really follow suit and therefore shifted their focus to the development of SLR cameras, this did not mean that Canon stopped producing rangefinders. In fact, they brought out quite number of slightly different models with a confusing range of names. The 1959 Canon P was one of these. It was a simplified and thus cheaper version of the Canon VI L. The P missed the switchable optical viewfinder for use with wide angle lenses and to get rangefinder magnification. Canon introduced two more rangefinders after the P, the 7 and the 7S, which were equipped with build-in lightmeters.
A Canon P with Canon 50mm f/1.4 lens, a wonderful piece of glass developed from the Serenar f/1.8 described above with the Canon II-F, having a similar optical design with 6 elements in 4 groups.
Although Steinheil München has a great reputation as a lens manufacturer, it is not very well known that for a short while the company also tried to gain ground as camera maker. In the late 1940s Steinheil produced two rather remarkable and unique cameras, the Casca I and Casca II. They were focal plane cameras, like Leicas, and perhaps this became the cameras downfall as the rumour goes that their production was halted due to infringements of Leitz patents. True or not, Leitz probably would not have cared so much if these cameras would not have been so far ahead of their time. Particularly the Casca II was a bit of a marvel, with a large brightline viewfinder with projected frame lines for telelenses and a unique bayonet lens mount with a range of lenses of four different focal lengths from 35 to 135 mm.
The Casca I pictured below was more conventional, although it did share its more advanced brother's unique look. However, it missed a rangefinder and slow shutter speeds and the lens bayonet was different so that lenses were not interchangeable between both Casca models.
A Steinheil Casca with Culminar 5 cm f/2.8 lens. Perhaps not the prettiest camera but certainly unique. The lens was focussed by rotating the serrated wheel visible on top of the large black knob, but I don't really get the point as the lens was more easily focussed by turning the base of the lens itself. Also one tends to rub one's finder over the front plate, which is perhaps why many Casca's show wear marks there, including this one.
A Steinheil Casca from behind. Note the unique shutter speed selector in the form of a sliding lever at the rear of the top housing. The back of the camera would hinge upwards, making it easy to load film.
Top view of the Steinheil Casca. For those fooled into thinking this was a rollfilm camera due to the lack of a rewind knob, the wind knob also served as a rewind knob. The little black knob on top of the camera switches its function.
My Steinheil Casca came with a non-working shutter, so I made a (so far unsuccessful) attempt at fixing it. The photo on the left shows the body with metal coverings removed, I just re-attached the wind knob for testing the wind mechanism. Note the black paper covering most of the front, including the rangefinder windows for the Casca II.
Top right is the shutter mechanism, which apparently incurred the wrath of Leitz. Only one curtain moves in this example. Bottom right is a top view, which shows the reinforced base plate for the accessory shoe. Also note the viewfinder, just a simple Galilean type not unlike the ones on early folding Retinas and nothing like the one on the Casca II.
Another interesting but less advanced 'Leica copy' was the INA Navax. It was made ca. 1955 by a company which, rather unusually, started with building wooden hand carts (apparently in high demand just after WWII) and then started producing roller bearings. The company still exists. It only ever produced one camera, the Navax, although there is mention that Feinwerktechnik GmbH in Lahr, which made the Mec 16 submini camera, was a subsidiary from INA.
The Navax was a viewfinder camera with a metal focal plane shutter which moved vertically. It used 35mm film but the frame size was only 32x22mm, like the early Minolta 35 and Nikon rangefinders. It featured a wind lever and flash synchronisation, but was let down by its simple viewfinder. It came with a Roeschlein-Kreuznach Pointar 45mm f/2.8 lens, which was decent enough but not of Leica quality (and in fact designed for the Braun Paxette mount, see figure caption). All in all, the Navax was a well-build camera, but rather big and clumsy for its features. It is therefore no surprise that it was only produced in very small quantities.
An INA Navax with Roeschlein-Kreuznach Pointar 45mm f/2.8 lens. This was the standard lens for this camera, but somewhat ironically, it was a lens designed for the Braun Paxette mount (like the Leica, a 39mm screw thread but with a longer register distance) and was fitted onto the Navax by means of an adapter ring, which is visible at the base of the lens.
The Leica M3 was introduced in 1954 to replace the screwmount Leicas, which by then were based on a twenty-year old design. The new camera was revolutionary. It had a bayonet mount for rapid lens changing. It had frame lines for different focal lengths projected in the viewfinder. These frame lines were parallax corrected. The viewfinder was bright with a nearly 1:1 view and a very bright and sharp rangefinder patch. It had all shutter speeds available with a single speed dial. It had a windlever. It had a back that would flip open for easier film loading. And last but not least: it was fully compatible with screw-mount lenses. Some of the features had been introduced before, but the M3 was the complete package and build to an extremely high standard. This was at a time Kodak had just introduced their first rangefinder folding cameras, the IIc and IIIc, Canon still copied Leica III series cameras, and Nikon had barely evolved to models that could match the Contax it was based on. Interchangeable lenses needed additional viewfinders on the camera (as on the Diax range) or as accessories (like the Voigtlander Turnit for the Prominent).
The effect was near immediate. The M3 sold well. Other manufacturers introduced models with multiple framelines. Viewfinders were made larger and brighter. Canon introduced the VT in 1956 as their first rangefinder which no longer emulating the screwmount Leicas. Nikon introduced the superb SP in 1957. And Canon and Nikon started to invest in developing SLR cameras, which would soon take over the world. So perhaps the introduction of the Leica M3, the ultimate rangefinder, started or at least accelerated the demise of that very type of camera.
A Leica M3 with Summicron 50mm f/2 collapsible lens. This example from early 1957 is a double stroke model, later production had a single stroke windlever.
Rear view of a Leica M3, showing two flash connectors and the hinged camera back with film reminder dial.
(left) The same Leica M3 with Summaron 35mm f/3.5 lens. As the viewfinder of the M3 had too large a view for 35mm frame lines to be fitted, a set of 'spectacles' was needed which would make the 50mm frame lines appear wider and adjust the focus of the rangefinder patch accordingly. The later M2 had a reduced viewfinder view and therefore a build-in 35mm frame. The spectacles can be removed from the lens by setting the focus to infinity and unscrewing the locking nut on top. A little ball hidden under the spectacles then serves as an infinity lock.
(right) A Leica M3 with Leitz MC meter (by Metrawatt). This light meter coupled to the speed dial, especially useful when working with fixed aperture.
(left) Detail of the M3 bayonet lens mount. The lens was secured by the push button on the left. The lever on the left is the selftimer, the lever on the right determines which frames are visible in the viewfinder. In this position it shows the frame for the 90mm lens, when pushed to the left it shows the 135mm frame, in the middle it shows the 50mm frame only.
(right) Leica M3 with 90mm screwmount Elmar mounted. The M3 was fully backwards compatible with screwmount lenses, including rangefinder coupling, through an adapter ring. Different rings were available for different focal lengths, so that the proper frame lines would be projected. This system was continued with later Leica M models, which had more frame lines available than the M3.
So here is another M3, this is a really early one from 1954 with a serial# in the 705,000 range, whilst the M3 production started with serial# 700,000 with a batch of 10,000 cameras, including this one. The lens is a fairly rare Elmar f/3.5, I didn't even realise this existed in M mount as I had only seen the f/2.8 version. However, the latter was only introduced in 1957, so it makes sense early M3s came with an f/3.5 Elmar. Early M3s did not have the frame line preview lever, whereas it is present on this example and must be a later update.
Upon comparing this M3 with the other one above there are quite a few small differences. some documented, some not. I've marked them in the above picture, with the earlier model to the left or at the top of the comparison pictures. The top plate screws disappeared on serial# 728,000, whereas the new shutter speed sequence was introduced on serial# 854,000. Note that the cover material on the back plate on the earlier example (right side bottom right photo) is non-original. Also note the backdoor is slightly smaller on the earlier model.
The Nikon S2 was introduced in 1955, two years after the Leica M3 and therefore a little too late perhaps. Nevertheless, it was a great and attractive-looking camera that still has a great reputation. It had a 1:1 viewfinder that was nearly as good as the SBOOI Leitz accessory viewfinder, but not quite as good as the one on the Leica M3. It also had a lever wind as well as a lever rewind, much more convenient than the wind knobs on earlier models. Finally, it had a removable back for easy film loading.
What remained compared to earlier Nikons was the camera design itself, which was heavily based on the Zeiss Contax II with a bit of Leica thrown in. This particularly applied to the lens focus design, which was identical to the Contax, with the focussing helicoid built into the camera body. Hence, the standard lenses have no focussing mechanism. Wide and telelenses were mounted on a larger bayonet mount, again similar to the Contax range. The lenses are therefore in principle interchangeable, although there are reports that the focussing helicoid for the standard lens is slightly different, leading to incompatibility problems for fast lenses at close range. In contrast to the Contax the Nikon S2 had a horizontally travelling cloth shutter, similar to the Leicas, and therefore the dials on top of the camera are more Leica than Contax too.
The very handsome Nikon S2, here with Nikkor-S.C 50mm f/1.4 lens. The lens was one of the few advantages Nikon had over Leica, who did not introduce a similarly fast lens until the 1960s.
Who thought Nikon gave up on rangefinders after the S2 would be mistaken, they continued to improve their design and introduced the Nikon SP only two years after the S2. At this moment Nikon had pretty much caught up with Leica and today an SP will fetch more than an M3 (as they are much harder to find). Note that the slightly later Nikon S3 and S4 were cheaper versions of the SP. After this Nikon introduced the F range SLR cameras and their success and ease of use essentially doomed any further development of rangefinder cameras.
