28mm is a well-known focal length for full-frame cameras (most cell phone cameras are 28mm). I would not recommend this lens for crop sensors. This is my new universal lens. It's fast, sharp, not too wide and not too narrow. You have to be pretty close for each portrait, but when my model is a 6 month old girl, it's not a big deal. The autofocus is quite noisy and could be better, but the image quality is excellent.
