Looks valuable, but a lot of vignetting and keystrokes (min / max) not exactly
The filter looks valuable and the packaging is good. Unfortunately, my copy showed clear vignettes in the direction of both ND32 and ND2 and thus made the filter virtually unusable. In addition, the minimum stop was not clean, so that a clear darkening was already visible at the minimum (> ND2), only a little further I had actually turned ND2. So it went from slightly darkened (> ND2) to light (ND2) to clearly darkened (ND32). It's a shame, but that's why I sent the filter back. I then did not examine the glass quality more closely.
