The non-rotating front on the Canon EF 28mm f/2.8 is a real plus. When you use rotary filters--such as circular polarizer, star, graduated, etc.--you won't have to constantly adjust your fitter after every focus. However, the focus element does extend and retract, at the front of the lens. The front focus element has a 52mm filter thread, the smallest filter diameter you'll ever find on any EF lens.

Canon's other current 28mm prime, the Canon EF 28mm f/1.8 USM Lens, also proved noticeably sharper than the Canon EF 28mm f/2.8 Lens - even with both lenses wide open. I regard the Canon EF 28mm f/1.8 USM Lens as a better lens in most categories - but the better performance is not lost on the price.
