recommended not even to "trial and error"

Before I bought this filter set, I have screw-on filters (eg, Haida) used. I wanted to watch as an alternative to screw filters a retention system. Even before the purchase I was skeptical as to whether one can get a product that works of this magnitude for this price. My expectations were therefore very low from the start. Even these were not met.

My biggest criticisms:

- Already the second use of the filter holder when attaching the adaptation is broken on the lens. This break I have temporarily glued to me to make at least an opinion on the overall quality of the filter.

- I tested mostly on a lens with 72mm thread diameter: Here occurred an unacceptable vignetting

- The biggest drawback though is the overall picture quality: see the pictures with attached filter out weak and milky. Contrast and clear contours in vain. Also of sharpness can be no question.

+ The bag is practically

My Recommendation:
Although first want to try something around is serving more much better with a product (eg, single Screw Filter) for 10-20 EUR. Again, again: Who approves buys, buys twice.
