The exterior finish of the ND filter is good, even the thread goes without problems and on the lens, the function of the filter is also properly.
Now the but, the filter distorts the image in some places so there is blurring, and not 100% darkens evenly. Therefore, there is 1 point deduction, I really wanted to just pull two, but this is good value for money you can not expect a top product.
At a Glance:
+ Good Price
+ Good workmanship
+ For practicing and experimenting enough
- Uneven sharpness
- Uneven darkening
Conclusion: I would the filters for each with a small purse recommend just want to experiment a little, amateur photographers and professionals who want to work with it often do not come around it on a good brand product.
Little tip: I'm going to order her my filter for the lens with the greatest Druchmesser through filter rings (8 euros for a whole set) I can then use the filters on all lenses.
