Processing:
- The filter can be screwed properly and lose weight
- The adjustment ring sits precisely, the game is very limited,
- Despite Slimbauweise very good handling, even when using a lens hood
- High-quality glass
Photo quality:
- When the lens used no vignetting (even in addition mounted UV filters (Slim) when these as protection always has on the lens and not want to lose weight!)
- Very good polarization effect
- No waste of the effect to the outer edge, but consistent "discoloration" of the image
- No perceptible loss of sharpness, only recognizable in really petty control during photo editing
- It lost only one f-stop
Packing:
I was a bit surprised that the filter was eifach etc. supplied in a plastic box so without foam inserts. I'm a bit sensitive when the filter in your pocket always rattles in its protective cover, which must in a high-quality product really is not.
All in all a very good choice with 100% buy recommendation. Maybe get a few more minutes, to access the Case Work with padding equip when a clatter even bother if you are traveling with backpack ;-)
