One thing is certain times that I could get reflections from windows and monitors with corresponding rotation. But the thing was intended.
But when bekenndender Himmelblau fanatic I can not confirm that it is possible in this regard to achieve notable effects. Or am I just too stupid ;-)
Mechanically it can be rotated smoothly on the filter thread of the lens, but to be able to turn the filter even in his own freewheeling to service, you have to grab something solid when screwing. And then it can logically be a bit trickier when slackened. A slightly coarser and more sublime teeth on the outer edge could therefore not harm undedingt, but with a little good will it works.
