I just purchased a chrome Nikon FM3A - I really like the FE series classic cameras and ergonomic handling, so this more expensive and recent production model is a treat. I would have been a fan of the mechanical FM series, but I was amazed to find out how far AE can go beyond the discrete shutter speed dial. I note that the FM3A "improved" split-prism screen does work as mentioned - the two halves do not darken, but to my surprise, I have a more difficult time focusing using this improved prism, as there appears to be less dramatic contrast. This is something that needs to be experienced to understand the difference. Perhaps I tested it on poor contrast lines. The overall screen is brighter than my FE screen. I will get the plain matte screen to see how it behaves. I am facing a personal challenge - to find an equal viewfinder experience in any classic camera to the Nikon F4 with its standard AF screen, in terms of viewing and the feel of capturing a manual focus. While I admire the focus assist indicator, I won't include this requirement, as well as the internal diopter. I do not wish to kindle a debate, but I feel that the F4 is a great camera that crosses over the Nikon classic camera line into the next generation - more in terms of ergonomic feel (bulky), power requirements (a lot of batteries), and use of exterior composite materials rather than metals. If I offend anyone, I am willing to say I feel that the F4 is technically the best camera I will ever own. I will eventually part with it (I think) when I find or figure out how to render a classic camera with a viewfinder and screen that is as liberating as the F4. I wish Nikon had offered a FE series size camera with the F4 viewfinder and manual focus abilities only ("F4MF") and produced another camera for AF like the one we see today. I know, I am very spoiled enjoying classic cameras with hindsight. Some say the Leicaflex models have great viewfinders. I bought an original Leicaflex, but was somewhat unhappy with the seller's operational claim and lack of final check before sending it, and my frustration with availability of R lenses. While it is one heck of a classic camera, I could not warm up to its ergonomic feel in my hands - it has a bloated feel to it. I have read that the SL2 has excellent focus snap. If you have had experience viewing an F4 viewfinder w/ AF screen, and own a classic camera (any brand) with a comparable view and focus ability, I am all ears. I also wonder if lenses can affect focus snap as well. Trivia question - What manual focus-only camera offered a focus assist indicator light like the F4? Hint - don't limit your mental search within Nikon.
