I was digging around in some MEs that I have collected over the years and found something interesting that seem to just blend in: A Pentax MF. At first I was throw for a loop because I could no see that "ME" on the left side, but then I saw the MF and I right away did some research. I found out that this camera was used to take pictures on medical equipment (I think this one was for optometry). From what I can tell I have the second version of this camera because it is full framed. The really cool one to have would be the first model that (from what I read) is a half framed. I'm sure lots of people here on the forums know much more about this camera than I, but I just wanted to share some pictures of it!
