- When Focus I notice personally no loss. All three filters are as sharp as without a filter to my mind to the brim.
- I could notice a slight color cast, as in other reviews. This in my opinion is low and can be compensated well with the RAW development.
- From the calculated exposure I had slight variations. This can be more or less offset in the RAW development with post-exposure. But you can also adjust the exposure time slightly from the calculated so that it well be true. Thus, the values 0.9, 1.8 and 3.0 fit well. (For calculation I use ND filter Calc for Android)
- You are really slim (thin), combining 24 mm and two filters I had only a little darkening in the image corners. (However, this was at 40 seconds, and ISO 25600, which had left only strengthens the vignetting of the lens..)
- Should have the different labels they ... This is at this / not my case.
- The stack of metal caps are a very space-saving solution compared to a box for each filter and you do not have x box out of his pocket to pull the right filter in hand to have.
- I have at a rating (in other Filtergöße) read that the thread will be very bad. This I can not confirm. The filter and the protective caps can be good up / screwing.
My Conclusion:
Compared to the Walimex they are definitely the better choice. You have a much lower color cast, are keen on the edge and the ND values fit.
Too expensive Hoya, B & W and Co, the Haida are absolutely for me the cheaper alternative. Also from this expensive one reads color casts and here there are three filters for the price and not only a filter. (My Hoya goes easily into cyan)
