I still haven't found a camera that does things better than my F3. Sure, one of the reasons is that I have gotten so used to it that anything else is "just not like F3", but that counts for something too, right?
There is only one other camera that felt perfect and didn't make me wish I was holding the F3 instead - Leicaflex SL - but its finder was so yellow that it was pretty much unusable. I would love to get my hands on another in good condition, but that would be costly as I have only two lenses for it (Angenieux 45-90/2.8 and Leitz Macro-Elmarit 60/2.8).
There is only one other camera that I would like to try before I stop looking around in interest and that is the Pentax LX.
