The picture quality is also very good. Light dimmed takes the edge clearly to the brim. At f8 to f11 the lens brings the maximum sharpness and very good results.
The price / performance ratio is very good. Comparable lenses from Canon and Nikon are more expensive, but the Walimex also has no auto focus and only a manual iris control. But that does not bother me really, I use it anyway only with Tripod and static subjects.
Somewhere under the line a great lens with very good P / L ratio, which is fun for both the Crop and at full frame.
