So I went and did it. I've been shooting with my new Canon 5dmkiii with 24-105 zoom lens for a couple of weeks now. I finally uploaded the images tonight and was really excited to see how much more clarity and quality I had purchased compared to my old 5D 107-135 combination. My first image was significantly blurred on the right quarter of the image. Hard to tell until I enlarged it. Great on the left side - totally unacceptable on the left... its a big file - hope it loads on here so anyone can comment after comparing right and left sides. It could be the lens but I bought it as a kit so the kit goes back to Amazon.

Any thoughts, boys and girls?

NYjoe - I use the 5d III upgraded from a 7D - and I am thrilled with the output. A cautionary note, though - I was not at all happy with the 24-105mm L - pictures just weren't popping sharp. I moved to a 24-70mm 2.8 L Version 1 (wish I could afford the V2), and there was a huge difference in quality. I get great results with my other L lenses and the 100mm Macro as well.

And hard to see much if you don't check "store original". The only thing I can see is that the leaves on the right, which are farther away than the leaves on the left, are not as clear.

Classic example of lack of understanding of your equipment. What shutter speed were you using?

Bingo, right here. 24-70 f2.8 a 100 macro, and 70-200 f2.8L might be the way to go. Images will be razor sharp.

Thanks for the Bingo. The 100 Macro works well also as a prime. The 300mm F4 L IS is also one of Canon's best primes even when coupled with the 1.4 extender.

David....shutter at 125 in shutter priority. Also shot at 60 with a steadying monopod. Same prob. I checked other shots I took on the same day and they all were inconsistent on the right side. But this one really stands out. The motor on the left was clearly visible...and just a gray blur on the right side. I never saw such a difference in any ofmy old 5d images. What do you suggest I try?

sounds like the lens has a manufacturing defect - its been known to happen - even with Canon. My guess is that there is an element centering issue. Return the lens and get a new one.

Exif data says 1/10th sec. not 1/125th sec. Even on a monopod just squeezing the shutter button can twist the camera enough to introduce blur. I am an expert at moving the camera as I take the picture! Do some test shots using a fast shutter speed or tripod or both.

Sigma has come out with a 24-105mm, f/4 lens. You may wish to try this lens. It has received good reviews. I own it, and find it produces very sharp images paired with my Canon 6D. For those shooters who complain about weight, know that this Sigma lens weighs more than the Canon version.

You could rent to try this lens before you buy:

www.borrowlenses.com

BTW: I used to own the Canon 24-105mm, f/4 lens, and took hundreds of pictures using it in national parks with nice results. My copy, however, did show some softness in the corners. This softness became noticeable only by looking for it. Bear in my mind, too, that our human perception ignores this corner softness because it gives most attention to the center of the images.

Experts also suggest that the shooter can crop the resulting image to remove the soft corners and edges. This technique generally requires capturing a wider image of the scene for later cropping.

so ths is one image, in going over all your images , was this a consistant pattern? even with the best equipment you will get a few that are below expectation. no one on this site will claim perfection 100% of the time, will they?

I have the Canon 24-105 L and it seems very sharp on my 6D. I suspect the 1/10 shutter speed is the real problem. Also what did you focus on? If super sharpness is the goal I would go with a prime.
