The HDR thing sounds ok..but it's not enough really.
No doubt many will be happy. But to me, for the A550, it's going to be £800+ body only, to have that stuff (MLU, DMR, AEL spot toggle etc etc usual list
missing in this price range is unforgivable really.
You know what, I'll just plonk along with the A200 and 5d, both have warts, but deliver well in the bang per buck dept, I'll either hunt out an A700 at some point, or just fall back into a few 5/7d ebay jobs. Also got my numerous film bodies to play with, and I enjoy the film thing too. Bit sad older cheap film bodies are starting to be better featured than many Sony digitals, still if that's the way they want it..up to them. Features are not everything, but I am no fan of gimmicks like smile detection..
One day Sony might invite a few photographers to wander around their Alpha building, it would do them the world of good, too bad the marketing Sony folks have taken it over, and geared it almost exclusively to consumers.
