The first impression was positive, quite similar to the color. However, looking at it then the set screw, then the pleasure has been an end. The thread is added and after Plasters it is not smooth-running. The hardware store I get better screws!
Unfortunately, I can the knowledge of other comments, the ring would fit perfectly, not understand. I do not feel that you measure with the slide gauge, but I suspect that the metal ring without Filzschutz fits exactly. With the padding I must exert too much pressure to impose the ring. This has nothing to do with the fact that the lens must be firmly secured, this is simply a question of manufacturing precision. For this indeed is the fact that it fits in some buyers, while others do not!
For my 100 macro I have also bought a cheap tripod collar. With the I am satisfied - it is also so, but half a hundred at the risk of scratching my dear objective: no thanks! This thing goes back. For a little more than twice the price I have found the original, I have to stop what put it to me constantly annoy need.
Addendum on 22.2 .: In the meantime I have the original Stativschelle Canon. They must, of course, do not buy for 199.- Euro, this is simply not appropriate, it exists already for 130 Euro. Compared to the thing at issue here, the original is worth every euro! Fits (of course!) Like a glove, the locking screw locks with a click, and can then be (of course!) Easily tighten.
There are so many fine mechanical products that are worked perfectly for half a hundred that I look at it in the present case for an outrage if this Stativschelle is so inferior to the price, or - for that matter, - so has large manufacturing tolerances, that they in a case does not fit in the other.
I reduce my rating therefore to a point!
