Outstanding lens for street photography and one of Erwin Put's favorites!

I mainly use the legendary 50 summilux asph in my m9. Once I thought about buying a wide-angle lens that fits in my work: Light, small and as sharp as possible. I used to use one of my 35mm to do the work, but as you guys know, 35mm is anything BUT wide-angle.

Durable; Lightweight; Strong Construction

I have had this lense for merely 3 month, used it frequently and I am absolutely in love with it. The sharpness is just amazing. The link shows three stiched images of Chicago's Wrigely field, taken hand held, http://pfaufoto.smugmug.com/Landscapes-Cityscapes#!

This lens with its handy dimensions is distinguished by very high image quality and a very wide image angle - making it a particularly practical wide-angle lens. It is suitable for a very wide range of uses for everything from daytime reportage to landscape and travel photography.
