Best Q lens so far.Virtually no barrel distortion, which is an issue with other Q lenses. Sharp across the frame and a very wide zoom range.

It's a great, sharp, fast lens for Q system cameras. Exactly what I wanted. It is VERY wide angle ... just short of fish-eye, so be sure that's what you really want.
