One of the reasons I dislike the F3 is was styled by Georgetto Giugiaro an Italian industrial designer and it looks to me more like a fashion item with the flattened prism top shape and the red stripe than a classic camera should, the F and the F2 do look like the classics they definitely are.
Personally, I love the functionality and features of the F3. The looks? Well, let's just say that was the beginning of the end for the F series. When you get to the F5, you're rapidly sliding down the ugly camera slope. Ugly aside, it is my go-to camera for sports. Especially, difficult shooting conditions in the variable atmosphere of a cyclocross race.
