Some of my most captivating and satisfying street photography pictures were taken with this lens. Sharpness is excellent, also at 2.8. In comparison to a 90 Summicron, it is very light and compact, not even making your camera front-heavy. This one has to clear space for a 90 cron, so I’m selling it. Safe to say I’m going to miss it and hoping the cron performs equally good. Hoping it goes to a creative, new home!
