Bolta Photavit IV


Today, after a long time I'm again presenting a really small 35 mm film camera, from which I already have some in my collection (Braun Paxette Ib , Rollei 35, Robot Junior, Olympus XA , ...). In this case as with the Robot not the full 24x36 mm will be exposed to light, but a special square format of 25x25 mm. In addition you can't use commercially available 135 cartridges. However, when it appeared on the market in 1948 the Photavit IV was correctly advertised as smallest camera for 35 mm film, although its even smaller predecessors left the Bolta plant in Nuremberg already since 1935.


The image format of 25x25 mm overlaps somewhat with the perforation of the standard 35 mm film. The reason is that Bolta's cameras originally used its own 35 mm (unperforated) film with a paper back delivered in respective Bolta cartridges. From a 36 frame 135 film you can fill the Bolta cartridges (25 images) twice using the provided rewinding device. I tried it once, only with an already exposed test film, and found it quite complicated. I'm still undecided whether I should risk a fresh roll of film. Particullaly, because I do not know how to get the exposed film back into the normal cartridge for developing.
The smallest camera for 35 mm film in my possession
There are some excellent sites dedicated to Photavit cameras (see links below). I will not repeat it all here. While reading and looking at my camera, I discovered a previously not covered circumstance. Most sites assume that the individual Photavit models followed each other in time. The serial number of my copy (# 28329) however, is higher than what CJ indicates for Model IV or even the "successor" V. Therefore, I believe that the Photavit V was introduced in 1951 as a low cost model and produced parallel to the IV. Both share the same serial number range. Based on the Schneider lens' serial number it is possible to date my copy at the end of 1952 or beginning of 1953.
