Every time somebody bumps up the number of megapixels, there's always another set of blog posts about how useless the megapixel race is. But I don't think they get it right all the time...
Several years ago, I looked up how big the old APS film cameras were, under the assumption that, given that a dSLR is the same size as an old film SLR, it will eventually be possible to make an APS-C digital camera the same size as an old APS film cmaera. This turns out to be awfully small, especially with a prime lens. I also eventually read about the Olympus PEN series. And the Pentax Auto 110 SLR system.
One of the central arguments of the 4/3rds mount was that digital camera sensors were destined to stay small, thus, a new mount for these smaller sensors, with a smaller lens throat and registration distance so that the lenses could be smaller and lighter, only covering that 4/3rds mount size. Of course, Olympus kinda screwed it up.
There's been some hope that we're going to stop seeing the fairly stupid megapixel race progress and might actually see some new features in cameras. As usual, it didn't happen this PMA.
Because I view my "primary" cameras as being best carried as clusters of heavy but high-quality hardware, I've realized that I'm really a Serious Compact junkie without realizing it.
