Every now and then. When shooting film, I switched between an F4, F3HP, and Pentax LX.
I like the F3 the most. It's seriously built like a tank. In my opinion it's the best manual/manual focus SLR ever made. It just does everything right. I have 3 lenses but they do everything: (All Nikon AIS) 50mm f1.2 35mm f1.4 and an 85 f1.4
Kind of makes me a bit sad seeing them sitting in used stores for $200 in almost perfect condition. A part of me feels the need to rescue everyone I see in case of a later retro resurgence for 35mm film cameras.
I now use a Fuji X100T but if someone invented a digital back/add-on that could turn an F3 into digital, I would never use anything else.
