I just received the AKS-5 from that list, nice camera, very cool kit that came with it - it came with a special focusing cassette that you would put in to calibrate the camera before usage. So you take off the film cassette and install the calibrating one that has it's own optics, you adjust the focus and then you put the film cassette. I'll post pictures of that later. Seller I got it from has more of these cameras if anyone wants by the way, I can put you in touch, PM me.
Very cool Vlad! interesting feature Beautiful "250" Jacques! It seems to be repainted! But I had a very old "III" with original black paint in a beautiful order. Regards LP
