I have two Nikon Fs... But I don't have an F2... yet!
I was out with my F at the weekend and I met a friend who was out busking on the seafront. He used to be a photographer with The Times newspaper and we had a good chat about Nikons. He didn't have anything good to say about the F4 though as his fell to bits just out of warranty. A call to Nikon UK soon got him a replacement though but only after he suggested he was going to switch to Canon!
I've been using an F or a Nikkormat as my more-or-less daily vade mecum camera for about 15 years.
