Re: Canon 15-85 - left side of image is blurry

"I don't think there is anything wrong with the original sample shot."

 

That was my first thought, too.  I continue to think so as it is easy to confuse distortion as something more when it is not. The test will prove it.

Re: Canon 15-85 - left side of image is blurry

Thanks for the suggestions, I decided to try this with a whiteboard full of text and poiint my camera (placed on a tripod) at it.  I don't think the lens is decentered based on this test.

While the corners are a bit softer yes, it's not as noticable and I found sharpening it in Photoshop made it look significantly better (with the exception of the bottom right corner, which usually doesn't do that in my real world testing.)
