As a professional photographer, I would not be able to recommend this filter for professional uses. I could only recommend this for someone to get used to using filters. You would definitely need to buy an adapter in order to get this to fit on anything other than a wide angle lens, so please be aware of that before purchasing this filter. I would also recommend that you spend a bit more money to be able to get maximum level of use out of an ND filter because this filter only really works well up to a certain point before it starts to get spotty. I received this product in exchange for my honest review.
