Surfnron ... I would not make up your mind about the 50D just yet. I have had mine for about 4 days and have done extensive testing on all of the DPreview points including noise, DR, pixel sharpness etc. and I am seeing a much more positive performance from the camera than all of these comments would lead you to believe. I would wait a week or so for the more technical and experienced photographers to respond to some of the points in the DPreview material and bring some perspective to the discussion. It is a little early to make this prediction, but I suspect the 50D review on DPreview will be revised in the future or some of their testing procedures will be changed going forward.
Some trends that I would expect to see:
1. Better understanding of the improved resolution capable with the 50D. (For example, DPreview testing at f/8 with 50 1.4 is less than ideal on a crop camera. Stepping back to f/5.6 would have probably lead to different conclusions).
2. DR results on DPreview seem questionable to me after running my own tests. At the very least, misleading for real world performance for people using RAW.
3. Noise ... I can get better RAW noise performance out the 50D than these early results would indicate.
One thing that I don\'t need to do any more testing on is the Micro Adjust on AF. This feature alone is worth the upgrade. Perhaps the 50D is going to be a camera that ends up asking more from the user in terms of technique and post processing. Software and the user knowledge may be items that will start to make a bigger difference going forward than they have in the past.
Well ... I\'m a little down after wrapping up my 50D vs 40D comparison. Everything (extra detail, DR, AF Micro Adjust, LCD, Live View enhancement) all checked out to my satisfaction. BUT, noise is much worst on the 50D (my tests were performed with ACR 4.6 & 5.1). It is a big step backwards. I\'m not going to try and describe the difference ... I have a 5MB file with test crops, but it is to large to host on my normal internet provider\'s (Comcast) free web hosting service.
