Hello folks, here is another project I made during the lockdown. It's a 35mm f2.8 rangefinder coupled(!) lens for LTM mount, which I made from various old lens parts. Donor for the optics was a Canon AF35M, better known as the Autoboy. I think it's a 4 element Tessar formula with multicoating. Little soft wide open, with rather strong vignetting, but very sharp and contrasty stopped down, with typical 80's look. The body of the lens was made from various junk lens parts I found at home, the helicoid is from Industar 50-2, the mount was from Industar 26M, the front plate is from Domiplan 2.8/50, the aperture from another lens....It was a trial-error type of work, so I don't have photos from the production, but it looks and works really great on my Canon P. The aperture is set by rotating the whole front plate, it has a focusing tab, it's also rangefinder coupled, which was the hardest part of the process. I sanded it a little, then checked, sanded, checked, sanded, checked, sanded, checked, sanded, checked.......The lens sits deep because the flange distance of the donor camera was very short, but this way the body works also as a built in hood/protection so there is no need for lens caps(which I hate anyway) and it's still very compact. hope you'll like it 🙂
