After learning how to use 600 film in a Spectra camera, I have decided to try to resurrect one of the most unknown Polaroid formats, Autofilm.

I had never heard of autofilm until recently, way back in 2015, when I first got into photography, I thrifted a box of Polaroid pictures with one of them much larger than a 600 picture, which I assumed to be spectra. A few weeks ago I bit the bullet and bought my first, and last pack of spectra to try out the format 1 time, and use the cartridge for reloading with 600 film. (I did this so I can ustalize the macro 5 slr and the double exposure feature of the spectra pro. After taking my first spectra picture, I realized its much smaller than this mysterious picture I found years ago. After doing ALOT of digging (there is very little information about it online), here is what I've found so far.

The only camera I have found that uses this autofilm is a Polaroid Microcam, it is an SLR (yes you heard that right) designed to be hooked to a microscope. The camera has automatic exposure settings from 1/60s to 16 minutes, as well as manual exposure of up to 10 hours! exposure control is /- 4 stops in 1/3 stop increments. Single lens reflex viewing with a glass lens

Autofilm is much bigger than even spectra film Autofilm: Frame 4.5x4.2 / image 3.0x4.0 Spectra: Frame 4.0x4.1 / image area 3.6x2.3 600 film: 3.5x4.2 / image area 3.1x3.0

Autofilm was available in: Type 331: 400 iso b&w Type 337: 3200 iso b&w Type 339: 640 iso color

The biggest pitfall of adapting spectra is that the spectra film is .1 inches shorter than 600 film, the good thing is autofilm is the same height, just 1 inch wider, this should make using the 600 film even simpler.

PROBELMS I MAY ENCOUNTER The best (and worst) part about this camera is that the film does not require batteries instead the camera has a 12V 1.2 amp DC power supply. This means that I will not have to mess with replacing film cartridge batteries, but I will have to use it indoors next to an outlet or buy a rechargeable portable DC power supply.

The lens is 10x magnification, but there is no indication of a focal length, and there is no way to focus the camera because it is intended to be used on a microscope (which can focus on its own).

If you know anything else about this camera or the autofilm format in general please let me know :)
