I'm currently running the first roll of film through my recently acquired Yashica Electro GSN. With a handy little adapter from The Yashica Guy, the electronic exposure function seems to be working. I've got a roll of TMax 400 in it, which is a bit too much ISO for bright sunny days and requires an aperture of around F16 in order for the camera to find a shutter speed that will work. It has a max. 1/500 sec.
