I agree, Sony is doing their own moving and shaking.
The in-camera hdr of the A500's looks brilliant (not in favour of the SD card thing on the A500's). I'm sure in-camera HDR will be in the next generation of the upper echelon of the Alpha's. I'm sure there'll be enhancements, and incremental improvements to it.
I'm sure 3D will change the SLR photographic topography, see Sony
. Can you imagine having to buy two 24-70mm CZ's? Or two 135mm STR's? It'll be a dream come true for CZ and Sony!
