- No color cast of about ND2 to ND50
- Thread fits gently and jolt-free on the lens
- Adjusting a larger diameter and therefore good rotation
- Effect of darkening clearly visible with naked eye
- No vignetting in the range of approximately ND2 to ND50 (the gray uniform)
- Fitting plastic pouch included
Negatives:
- Tag does not fit. Maximum of the marker about 30 ° offset from the real maximum of the filter
- From about ND50 grew stronger, Purple-color cast
- From about ND50-increasing vignetting
(See pictures)
Conclusion: The filter is quite nice to darken a motive, some aperture. For bulb exposures, in bright sunshine and open aperture only very limited use. But for nice blurred brook watercourses in the forest of the filter ranges from good.
