The following timeline records the development history of two milestones in camera design – the significance of the 35mm still camera film format and the adoption of the Single-Lens Reflex (SLR) physical design involving the instant-return mirror. Of the two, the SLR design has had a far longer gestation, adopted across photographic films that existed before the 35mm film was available. Through the development timeline, technologies and various features have also been introduced to the 35mm SLR camera from other form factors including rangefinders and even compact cameras. The timeline is also significant in underlining the emergence of Japan as the eventual power in the camera industry as it gradually eclipsed Germany and other European countries including USA once electronics became an invaluable aspect of (camera) design.

Asahi Pentax Spotmatic ES – first 35mm SLR with electronic aperture-priority auto mode; uses stop-down TTL metering; ES stands for Electro Spotmatic; sports an electronically-controlled shutter

Note: Cameras like the Spotmatic ES spelt the beginning of the end of the German domination of the camera industry. With increased implementation of electronics for auto exposure, the Japanese began to stretch their lead in the industry where and when the Germans were struggling to cope before they eventually gave up their market control.

Having struggled through the Sixties, many of the famous German brands began to wilt and go under the hammer. They included Exacta, Ikonta, Ihagee, Contax, Edixa, Rollei/Rolleiflex/Rolleicord, Leica and Voigtländer. All of these were either bankrupt or sold off. A few were contracted to East Asia for production.

A case in point was Voigtländer, which became a premium niche boutique brand, existing under the Cosina umbrella and now having a revitalised future servicing the mirrorless camera market that in itself is now threatening to cause the demise of the very format that destroyed Voigtländer in the first place – the Single-Lens Reflex.

Canon FTb – first 35mm SLR to support dedicated flash synchronisation hotshoe; additional flash contacts are available

Canon FD 55mm f1.2 AL – first 35mm SLR rectilinear aspheric lens

Fujica ST701 – first 35mm SLR to use silicon photodiode (SPD) metering cells in replacement of cadmium-sulphide (CdS), SPD cells are small enough to now be internalised within the camera

Note: Although CdS was the choice for many camera makers prior to this point, its effectiveness relied on bright lighting conditions after which there would be a ‘memory’ effect causing a sluggish response to changes in light level.

This sluggishness could be as much as 30 seconds before the meter could resume normal operation. SPD was far faster in reaction – just about instantaneous – but its infrared response quality required blue filtration in order that it matches the spectral response of the human eye. The overall performance and reliability of the SPD was more than enough to finally displace CdS by the late 1970’s especially after the Olympus OM-2’s SBCs (Silicon Blue Cell) proved the point so decisively.

Japan / West Germany

Takumar SMC lenses – first 35mm SLR lens system to feature multicoating; SMC stands for Super Multi Coating; designed for M42 screw-mount cameras; co-developed with Zeiss of Oberkochen

East Germany

Praktica LLC – first 35mm SLR to feature electric contacts at the lens mount, first with electromechanical lens diaphragm stop-down control; modified M42 lens mount for open-aperture metering

Note: Despite the remarkable universal pervasiveness of the M42 screw mount,its limitations proved unacceptable by early 1970s because by that time, the rise of electronics in the camera industry had forced the issue of electronic versus mechanical interfacing. Because M42 could not provide for auto-diaphragm lens open-aperture viewing and metering, it was in many ways the sounding death knell.

Asahi had been the most prolific in their attempts to modify the screw mount to bring into effect support for auto-diaphragm control with open-aperture metering but even they failed in the end. By 1975, Asahi finally abandoned the screw mount thus effectively ending the life of this design throughout the industry. It was also at this point that the company introduced the famous Pentax-K mount that provided just as universal.
