Here’s another one of my goofy projects. I had couple of Petri 2.8 Color Corrected Super rangefinder cameras from the 1960s that I picked up for peanuts. One day, I had a strange urge to try and convert one of the lens from the Petri into a Nikon F-Mount.
The lens on this Petri rangefinder is fixed, by the way. So I had to perform a major surgery to the camera before I was able to separate the lens from the body. As much as I tried I wasn’t able to salvage the focusing mechanical bits. The shutter mechanism that’s built into the lens barrel had to be removed since I didn’t need it and it was in the way. I was surprised to find a 10-blade aperture diaphragm on this budget model. The glass wasn’t in great shape but shots came out clean and surprisingly sharp.

Petri 4.5cm f/2.8 converted to Nikon F-Mount (notice the 10-blade aperture diaphragm!)

Doesn’t look all that bad on the Nikon D90.

Turn any lens into a Nikon F-Mount by using the Nikon body cap!
