And it should be good for many more! I have 2, used for over 20 years by a news reporter friend, mostly in Africa and the Middle East. They definitely show some battle scars, but are 100% functional. I have the battery holders to configure them as an F4, F4E, or F4S, also have an MF-23 data back and a Hi-Mag finder. Since obtaining these, my other 35mm cameras don't get much use. (I shoot mostly 120 film.)
I have photographs of my gear in a safe deposit box, but nothing's digitized. Somewhere around here I have a Df - one of these days I may break it out and copy some pictures to post here.
