I dragged a Nikon D80 out of retirement yesterday - it had been sitting in a drawer since I had bought a D7000. I sold the D7000 after using my EP3 for a month or two. So yesterday I was at a Cowboy Action shooting event as "the photographer" and figured for my own interest, I'd shoot the old D80 and the EP. I had an 18-200 on the Nikon and the 14-150, 12, and 45 for the EP. The Nikon was so much easier to actually USE. NO, not easier to carry, but just sort of natural to shoot. There was no thinking at all involved, no wondering if it would properly focus on action - just a series of properly exposed/perfectly focused shots. The EP did OK but there were a fair percentage of soft shots and a lot of looking to see what the settings were and changing between center weighted and spot. The fill flash on the nikon was consistently better as well and...yeah, an optical viewfinder really IS better... I'm in a total funk at the moment - I like the EP size but it really isn't as "natural" a camera to use as my old D80 (or my now-gone D700). It is a lot smaller though and its images are excellent when you factor out the mis-focused shots. I'm trying to decide whether to close out the M43 experiment or just keep doing it until I get it right. But the Nikon's never required any work to "get it right.
