Use this inexpensive way to put Zeiss wide glass on your Canon. My 28mm Contax lens is clean, no marks on glass; has had a Hoya UV on it since I got it. Few marks on the barrel. Adapter is the high quality Cosina sold by Stephen Gandy for $179. Allows infinity (manual) focus. This lens and my 1DS III are a great landscape combo. Both items sold as a package for $439 post paid
