I modified this one same as the necromatic, to use 35mm film force-fit into a 126 cartridge. This one turned out to be a lot simpler than the 134 – no rotating flash cube, simpler forward mechanism, etc. – but was still way overengineered. I also drilled out the aperture, if my calculations are correct, I opened it up from f/11 to f/4, and tomorrow I’m going to pick up a 180-degree door peep-hole from lowes to mount in front of the primary to make a psuedo-fisheye effect.
So, this one will be the fishtamatic. Photos to come.
