The Haida Pro 2 is a real buy recommendation for people who enjoy photography and like to try new ways. The results are professional and just do nothing but joy. Nevertheless, one should be aware of before buying, this is such a gray filter anything for someone who just wants to quickly take a picture once. After attachment of the filter no automatic focusing more is possible and manually you have to determine any chance the sharpness. In other words, focus without filter, turn off the auto-focus, filter screw, set exposure time up and test. Maybe rich 30 seconds maybe 2 minutes in the bulb mode. And the type of scene! I think that's a good thing, but everyone must make for themselves in order to avoid a bad buy.
In principle, this filter is absolutely comparable to almost three times as expensive brand filter. The brand filter has a slight red cast, this one has a slight blue tint. In other words, must be reworked the image when using both filters.
