Processing is quite good. Solid metal, non-slip rubber coating, ... As far as I'm satisfied.
The length is not overly. With under 40cm it fits into larger bags.
The base is also solid and wobbles no piece. Minimal movements are going into debt to the tripod, which are visible through the enormous focal length.
Up to this point the lens has ever brought solid 3 *.
What has this cost the lens star was this not super quality.
I had not reckoned with a glossy portion, but the CA at maximum aperture has made me even shudder. Even in center small snow piles of branches were reddish. Until the edge of it was slightly worse. On the PC there was nothing left to save.
Good results I could only shoot at f (and one step before) closed. Since the scores Walimex and proves that it's not just cheap. Image error I kommte no longer make. Another * more.
(Incidentally helps the Fade when focusing that despite tripod not easy (because the aforementioned wobbles) free-hand is nothing -.. Especially at this length)
What I missed at the delivery was a cover for the rear end. At least my delivery had only a small plastic bag pressed reinbekommen - the filter thread on the other hand had a lovely plastic cover. Filters but you can not unscrew.
The supplied Konvert ring was also defective. The inner ring (on which the lens is mounted) could rotate freely. That's a No, that's why we went back again. - With a super small screwdriver could have been the problem can solve probably, but such a miniature missing my range.
Conclusion: here is to have a really great message for small markets and the shutter is closed! Some practice it, then also the focusing is easy.
