I have a decent collection of M-42 (switched to EF) Soviet era stills lenses that I'll use on projects from time-to-time. While I was building that set, I stumbled upon the Japanese made, (perhaps 1980's vintage) Petri 55mm f1.8. This lens is quite small, but seems to be built well enough - the body is the typical black anodized alloy. The six bladed aperture adjusts from a bright f1.8 to an f16, range of focus is 2' to infinity, and the front filter thread is 52mm. The Petri C.C. Auto was originally meant to pair with the Petri FT EE camera body, and has a native M42 mount (my copy has been adapted to EF mount).

After some "customization" (there's only one copy in the world that looks specifically like mine) and testing of the lens I decided to rotate it into use. Because of the modifications, I'll refrain from any sort of formal review and just show you the results. Below are a series of stills I took with the lens on another trip to Mackinac Island, Michigan. For more general information about the lens from a great lens database please click the link here to visit allphotolenses.com. Any questions or comments can be dropped in the message board below.

All photos were captured on the Sony A7s with absolutely no post processing. For more info about the A7s, please click here.
