This is a fantastic lens, although due to its size and weight and the slower speed at f2.8 it may not be a all round general purpose lens. The photo taken by this lens has very high resolution and smooth appearance, and thus give you the medium format feel. When use for subjects at infinity it is good to stop down the lens to f4 or f5.6, otherwise it can be used comfortably with human subject at close to mid range.
