The lens reflects very sharp. The image quality is typically very high macro. Autofocus is rather slow, even for a macro. But the biggest problem is that the wiggle, the lenses in the lens, the lens when lifting it shows properly as the lenses abut.
I have posted the Obektiv because I believed it was a failure. After five weeks I got it with the error message "no fault could be detected" retour. Häte I saved a little longer and bought the original Canon.
