That was my take on the "bent stem" issue. But I'm not sure that is what we're supposed to be looking at. There are pronounced circular artifacts visible in the image. The most obvious are the ones centred in the frame (concentric with the circle added in the second, cropped, image), but there are several other rings visible toward the bottom of the image. I don't know what they are (and the presence of the non-central ones argues against an optical oddity of the lens), but I don't like them.
FWIW, I've never noticed anything like this in my 50-135 shots. On Wed, Nov 23, 2011 at 10:30:08AM -0500, Paul Stenquist wrote: > It's simply a depth of field issue.
