Excerpt: This is an amazing lens. And, for all its character, sharpness, rendering and clarity of micro contrast, color, etc... it is my all time favorite lens... for its IQ and appeal. Even though it is not generally my go to lens, it is the one lens I never want to be without.
Summary: I place a premium on lens quality and compactness, which are consistent with most Leica lenses. This lens is no exception. The performance is outstanding wide open, which is most obvious when you look at portraits on screen and zoom in 1:1 on the subject's eyes.
Excerpt: The resolution is almost clinical in nature, even when opened wide. Micro-contrast is high and can produce very compelling textures on your subjects. Contrast is also very high. Colors are exquisitely reproduced. If there are strong lights hitting the lens, it flares quite easily.
Pros: Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Excerpt: Awesome glass. I prefer this over the 90 APO ASPH as its a bit smaller and actually fills more of the frame due to the close focus limit. Renders very similar to the 50 Summilux ASPH and is ridiculously sharp wide open.
Excerpt: I have been a Leica rangefinder camera man all my life, M4, M6, and now the M9. My old Leica M lens are still very nice, but when I mounted the 75mm lens to my M9, the shots are beyond belief, the sharpness, contrast, and bokeh are so refined, it is like capturing life at that moment.
Excerpt: If you want to wring every pixel out of your M9 this is the way to go. This is the sharpest 35mm lens I have ever used, but it does so in a pleasing way. Simply amazing. Get this an a 35mm Summicron and you will be able to get 93% of the pictures you want.
Excerpt: [...] I didn't see how it could possibly live up to the hype written about it on the internet, but my opinion is now that it does, and then some. Images in the plane of focus are rendered undistorted, tack-sharp, and with a sense of immediacy that is a little hard to describe.
