I did a stint working on cruise liners... 1800 people in 2 sittings for dinner. Every night, brief was to get a picture of EVERYONE at their table. 2 man team, one shooting, one running back and forwards between the Photo Cabin and the dining rooms - back and forwards with around 50 rolls of film a night, frantically feeding the minilab, and dealing with the pictures printed - all of which had to be on display on the easels for 6:30am the following morning, so the holidaymakers could select their photo's and charge them to their rooms account. On average, I think we sold around 1 in 3 pictures. 2xEOS1's running 25 rolls a night each, 3 nights a week (3 nights shooting, 3 nights on the lab, and one night at the end of the cruise where no shooting happened) - I was grateful for the best camera I could get, and the most solid / reliable. Would have KILLED for digital, all on one or two cards, display the pictures on a couple of touch screens the following day, press a "buy" button and print on demand. BUT, at the time we used the best that was available.
(And co-incidentally - doing that for a short contract pretty much resulted in my on-going HATRED of actually pointing a camera at anything with a face (other than something like a town hall clock))
Thing is the F5 was a fantastic TOOL to do a JOB. Much as my digital kit (and my EOS-3 film camera) is. These days I don't shoot much paid work on film - but when I do, it's nice to have the appropriate tool for the job. And that's why, if I was bought into Nikon rather than Canon glass, the F5 would be pretty much at the top of my shopping list.
