I don't know how useful it really is for most users, but it's nice to have. The F4 has both an analog frame counter as well as a digital counter which can be seen inside the finder. Come to think of it, I've never looked in the viewfinder to see if the digital counter counts backward as the film rewinds. Unfortunately, my own F4 is resting in pieces. Towards the end of its life, the analog and digital frame counters didn't agree with each other!
