Here is a familiar question you have probably come across already, in part. Canon 30D VS Canon XTi. Realizing that there are alot of factors that make quality pictures, like glass, operation and what not, really, what about the CMOS size diference between these two cameras? I was almost had with the 10.1MP in the XTi... but knowing that there can be image degredation due to craming in a bunch o pixels and the likely varience between models in Canon's line up. Sure the XTi has a higher pixel count, but it is very slightly smaller than the 30D's sensor. The XTi has more pixels, the 30D has less. My question is really, how different are the sensors between these two cameras? Same materials used? I realize the functions of the 30D make it a better camera, but what about the picture quality? Is there a site that shows the exact difference of the sensors in these two cameras? Of course... avoiding the trade secrets and what not. Aw heck, I should just get the 30D... and maybe by the time I can get it they will have a "40D with Full Frame Sesnor". How sweet would that be! Er... maybe not if they sacrifice something to keep it in the same price range.
