first 10-20 pic

foregoing oldradiomans monstrous post...

I would call user error as neither shot look like a very good sampling of "sharpness" in my humble and most of the time worthless opinion.

Mr. Clean, That may well be true. However, one doesn't know for sure if lens quality is not known.

I think the sharpness is fine. But, you definatly have something else going on with all the noise.

Here is the full shot from the 24-105:

I have to agree with all the comments that have been made, however the noise issue seems to be the main problem. You also mention burst, does that mean that you actually shot 3 fps or so. If you were not shooting at a fast shutter speed, this may cause the sharpness to suffer, however probably not the problem. WHEN SHOOTING WHITE, must get proper exposure or will underexpose and cause noise. When I shoot a bride, I use manual and meter off the grass, or something that will yield 18% gray, then I will check the histogram watch for flashing overexposure. Photos must be properly exposed or the sharpness will suffer. Oldradioman has a good idea. Compare your lenses under controlled and identical conditions. obtw, I also have the 24-105 and my bet is, that it is sharper than most of the lenses in your bag.

Odd....I just got my 10-20 and it seems to be sharper than that

I don't think I am doing the "100% Crop" thing correctly. I zoom in until CS2 says I am at 100% and then I cropped a piece of the image, hit enter and saved as a jpeg. When I do this, there seems to be tons of noise in the picture. Almost like I made the picture too big and then cropped.
