Before I bought my F6, I owned the F100. The latch for the back on my F100 broke, as they are prone to do and I was frantic to fix it. Ultimately, I bought a used F100 for fifty odd bucks and stripped it of parts, back included. I felt sure I could keep my old F100 running forever on these extra parts. That is how much I love this camera. When I retired, I finally could afford an F6, so I bought one and all my affections were instantly transferred. Well, maybe not all my affections, but at least I felt I had a newer updated fancier F100. And that is my point. The F6 is a great film camera, but IMHO, it is a younger, finer, shapelier, and faster F100. If you can't afford an F6, get ahold of the ole' F100 until you can afford an F6.
