thats my testpics with the SMC-M 200mm 1:4f. Sure is a wonderful lens. I recommend you to get the Super Takumar 150mm 1:4f next, which is also amazing. All pictures in the above set is unedited except for witebalance, shot in RAW and converted to 100% jpgs, no sharpening added at all.
Here are some shots when I had it on camera, nothing spectacular though, I will however put up a proper testset for it aswell.

Tomorrow I'll update with S-M-C Takumar 300mm 1:4f which is also very good tbh.
