I've had a LOT of people give me the look when I told them I picked up the Alpha instead of waiting for the XTi. The reviews of the Alpha certainly aren't bad, but I get the impression that people consider the Rebel series the de facto standard for digital SLR's. I really like the image stabilization built into the camera, as it works quite well. The only weakness that this camera has that I can see is in regards to noise levels at ISO 800 and above. Your thoughts? Are the naysayers misinformed or Canon sackriders? Or are they right?
