What I liked:
+ Very nice colors
+ Very sharp
+ Fast Focus
+ Small construction
What went like this:
o fringing. With Lightroom goes but very good if you can simply enabled by default the corresponding function. These fringing at high-contrast edges I last saw at the old Nikon lenses from the late 80s / 90s.
What was less great:
- Large minimum focusing distance of 85cm. That's a little too far for my taste, especially in the full-frame without Crop Factor
- Autofocus screamed through my copy for permanent pronounced backfocus.
The last point has led to the sale, because on a 5D Mark 1 (Classic) the focus is not fine adjustment I ist.Hätte a 5D Mark II or a different model, in which the focus is on the body with fine adjustment for an objective, I would have the lens retain more.
