Instamatic SLR Comparison


I'm really proud to call them all my own now. And, moreover, every one of the five ever built Instamatic SLRs is in very good condition. Due to lack of available film I'll probably never really will take pictures with them ever again. Here is the promised comparison in tabular form:

As you can see at the production figures (* own estimate), none of them really was a hit. That's somehow not surprising. The Instamatic cartridge had (justifiably) the reputation of being suitable only for simple and inexpensive cameras. In particular, since the film flatness could not be adequately ensured. Therefore, the potential of high-performance lenses could not be utilized. Camera manufacturers should have been aware of that actually. Why then build a SLR even with interchangeable lenses?
Well, we are at the end of the 60s. The global camera market was on the rise for almost all camera classes. More and more cameras also reached into households, where never has been photographed before. And those amateurs with viewfinder cameras squinted forward to the SLRs. Therefore it is less surprising that the camera manufacturers tryed to occupy strange niches. The motives of the 5 manufacturers here were naturally not quite the same. But all had to deal with these cameras to perform a balancing act between the technical seriousness of the SLR and the demand for simplicity of the 126er cartridge. They all succeeded more or less. The two poles are the simple Keystone and the serious Contaflex. The Ricoh seems somehow not thought right to the end. The most successful - I think - are the Kodak and the Rollei. The well done system integration speaks for the Kodak, while the Rollei stands out the most by her excellent and consistent design as well as best execution.
However, latest in 1972 all understood that the Instamatic cartridge and high-end cameras do not fit together. But history repeats itself sometimes. As I have already posted, there was also the "new" Instamatic cartridge of the '70s (110, "Pocket Film") and of course again SLRs. Two out of three available I have in my collection (Pentax Auto 110 and Minolta 110 Zoom). And in the mid '90s there was a short appearance of APS SLR's, of which there are only a few models from five manufacturers.

Keystone K 1020 auto-instant Reflex

The first single lens reflex (SLR) for Kodak's Instamatic 126 cartridge comes formally from the US, but not by Kodak itself. In June 1966, three years after the yellow giant launched the 126 cartridge on the market, it was Keystone, number 3 of the US camera market (behind Kodak and Polaroid) to first pair the increasingly popular SLR concept with the instant loadable cassette. Keystone was rather active in the mass market for simple cameras and used Mamiya in Japan as a toll producer. Some elements of the Auto-Lux 35 might have been re-used. Although the first of total five 126 SLR's on the market, it always remained the cheapest with less than a $100 price tag (1967).
The camera itself is very simple and has almost no controls. Film loading, focus and shoot don't really require a manual, also the socket for the Sylvania flashcubes is fool-proof. The shutter priority automatic (with needle indicator in the viewfinder) is controlled by the selenium element, there is only one shutter speed (which is mentioned nowhere, probably 1/80 s). The manual reveals a different shutter speed for flash photography (but again not which, I'm guessing here 1/40 s). To ignite the N-flashcubes two alkaline batteries of size N are needed, otherwise the camera works without. The lens (48 mm f/2.8) is probably identical to the corresponding Mamiya Sekor, quite a decent Triplet.
During production of the K 1020 Keystone itself was aquired by  Berkey Photo and then moved from Boston, MA to Clifton, NJ. During the 70's they first increased their market share, but eventually they lost the competition against the giants from Rochester. After further owner changes they filed for bankruptcy in 1991. The fight with Kodak has been described in an article about Benjamin Berkey quite flowery. I wrote an e-mail to his son Harvey with some hope to find out further details about the K 1020, but without success. Therfore, it will probably remain a mystery how successful the camera was and how many copies were sold. My copy has cost me $ 6 plus freight, according to Collectiblend it is probably worth a little bit more.
