Super. 1880 4477

Super filter to engage in long exposures, at that price I can only recommend, the only alternatives are more expensive without really quality assurance (although Hoya has a good reputation), for the high-end equivalent c is 10x the price.

In terms of quality, packaging is already very classy, ​​with a rigid plastic box for transport and a cap and that's really cool because not necessary at the base. In terms of image, I shoot in RAW (EOS 550D / 1.8 50mm), I'm fairs over 30s is I have seen no loss of sharpness or odd color (which might have been without correcting problem anyway). In terms of use, I recommend to screw the filter carefully to avoid any risk of falling and systematically storing in its box (not in a bag hastily). To clean Hama I use a pen with a retractable brush and a buffer, it is findable on amazon and it's very good quality, perfect for filters and goals.
