Canon 15-85mm Lens Sharpness Feedback Needed
Oct 2, 2012

Dear all,

Initially posted this in SLR Lens talk, reposting here.

I recently bought a Canon 15-85mm as a travel lens for an upcoming trip. Here are some sample sharpness test photos and I seek your opinion/advice on its performance.

One important note: These are crops taken off-center. The center performance is pretty good for my eyes, so I didn't want to include them.

These pictures are taken on a tripod with MLU enabled and remote shutter to eliminate any camera shake (IS was turned off as well). To reduce the number of pictures, I have taken two images per focal length, one wide open and another stopped down to the next f-stop.

I appreciate your feedbacks.
