The reviews write that it is sharp . I didn’t get that. I'll write that it's dark, because field sharpness only after cover. As a plus, I will point out that it works well with macro rings. Imagine a macro with EGF 70-200, but you still have to clamp the hole, so it’s good with macro rings. And it automatically focuses with them, but you yourself understand that macro-almost always either manually or even with the apparatus. That's better. Like a portrait -0, but I didn’t count on it. Landscapes with small details in the corners are not his. However, he sold it, because found better quality, but not better in FR.
