Crisp clear images, faster AF and super brightness! My immerdrauf lens! I have it on my K-7 and the colors are great. Sharpness and image quality worlds better than the standard lenses! It could convince me in any aperture setting! Processing seems to me very valuable before (it wobbles and nothing rattles nothing) It does have, however, no ultrasonic motor I think the volume of AF is not really loud. Price-performance ablsolut unbeatable! Absolute buy recommendation!
