Compared to five years ago when the E-P1 first surfaced, things have changed dramatically. The Reichman article, The Full Frame Myth, gets right to the heart of it. We have a variety of half-frame sensors on FourThirds and APS-C formats that deliver astonishing images. The argument goes, then, that if you are not printing huge, full-frame is no longer needed. But ahem, he hedges on the Sony A7 account. Here is a full frame camera not much bigger than a PEN, but ahem, the lenses are huge, and very much more expensive. I you have to shoot full frame as a pro, that is not a problem, but if 99.7% of what you shoot takes no advantage of the special full frame privilege, why spend the money? Personally, I'd rather have twice as many lenses, a few pro-grade with fantastic prices, than feel cool about stuff I will never shoot. The point here is, with the maturity reached in current state of the art CMOS sensors, particularly in half-frame formats, we need to get off this old sensor fixation and get on with lens discomfort, specifically, the way things play out when a camera maker locks you into a particular line of really expensive lenses that were not designed for the format you are shooting. All of the interesting developments come from Sony, Fuji, and the FourThirds Duo, Olympus, and Panasonic. I am not sure the Nikon 1" cameras count as innovation or self-defense. I cannot remember, ever, having been this bored with Nikon and Canon as we look into the future. To the contrary, it seems they dread the future. If we say we have 1.33333" sensors (FourThirds), 1.8" and 2.775" (APSC and Full respectively), we are going to soon be drooling on 1.0" sensor cameras too. That RX-100 category is gonna be sweet. I have a funny feeling it will kill the TwoThirds (0.666" and 0.625") sensor category we see in the likes of XZ-2 and LX-5 cameras. And yes, I left out Samsung. I am not yet sold.
