I found that if you somehow managed to remove the electric eye filter (I tried to soak the joint with DCM, idk did it help) then you can clean it just by dipping in an acid solution

And thank you, Joaquin, for allowing Jake to post. You have helped a great many enthusiasts. I hope your OpenSX70 work continues apace! Gracias!

A wonderful, thorough, and well-written article. Thank you for your research and your fine explanation. These were certainly well crafted critters for their day--and surprisingly complicated. (And what in hell was in the coffee in Cambridge during the late 60s and early 70s?)

Tremendously informative article! Really fascinating. Thanks for sharing!

Wow, great article! Thank you!

What’s the fastest exposure time / ev value for the box onesteps? Someone on The Internet wrote 1/200s at f14.5, which would suggest that even with the camera mod the camera wouldn’t be fast enough for sunny or bright snow pictures with 600 film. You would need about 1/600 shutter speed by “sunny 16 rule”
