Very good filter, however, I could see a loss of quality in low light, for this reason I'm more night long breaks with this filter. For all other situations I have nothing to report it suits me perfectly. For those who are struggling to clean it, use a Lespen pen (a real one, not an infringement), the first time is very long, we think we will never see the end, as if the glass was very fat but for the following cleanings, it will be very quick and easy.
