I take this combination on my Tokina 28-70mm f2.6-2.8, since the original panel was worn and one comes only with luck and time somewhere on a spare part. Lens hood with threads are too cumbersome, I've tried. The clip-on visor fits perfectly here, at least in the DX format - even more perfect than the original, as it further extends forward slightly (and the Tokina is extremely vulnerable). In FX format they could possibly be too large. Less than a point deduction gets the combination, however the somewhat fiddly handling. You have to look closely and try around until the bezel is seated properly, and then the lid is also right on it. Since the cover is held by the same two "threads wings" that hold the iris on the lens, you can start only in a certain position to cover namely. And that is twisted normally even 90 ° (since one can not read the "Hama"!). Fair to say that that's just the necessary evil of this otherwise but very elegant solution. I can live with it and recommend it clear to all States who can not make friends with Schraubblenden.
