I am soliciting a recommendation for selecting one of the above cameras for viewfinder selection for whatever purpose you may have had when selecting and using viewfinders. I own and use all three models. I am curious to know if one of these models offer any advantage in viewfinder options. The F2 is somewhat different due to the uniqueness of a meter-less VF, as well as a switch between Non-AI and AI/AIS capabilities. I am currently not very pleased with the F3's meter readout in its viewfinder, but many F3 users have nevertheless enjoyed this camera. I only use the F4 for manual focusing with an AI lens, and I don't know how much I will use this model, as I favor small cameras. My interest has developed as a result of all of these dream cameras becoming available after the digital revolution has rendered film cameras more affordable.
