Petri 4.5cm f/2.8… F-Mount!

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.

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

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