I finally got an F4 not too long before I had a bad accident that curtailed my photographing for a while, after which I started traveling a lot and went to digital, and also about the same time my local processor stopped doing slides. I loved it when I used it, but confess I've put very little mileage on it in the last few years. Mine is an old one that looks as if was dug up out of someone's garden, bought very cheaply, with a little LCD bleed thrown in, but working perfectly. It also still has the alkaline batteries that were in it when I got it some time around 2012, which seem destined to outlive me. I got mine because it was so cheap at the time I could not resist it, and expected not to like it, but found it quite nice to use.
Like the reviewer, I never used it much for auto focus, but found it a great body for MF lenses, and despite my love for the F3 that came before it, I think the F4 got the exposures right with a bit less fuss.
