wanted to be able to shoot off camera flash without having to use HSS (high speed sync), so i did a little research and came to the conclusion that I needed an ND Filter. There are a lot of options out there but I knew the price point I was comfortable staying in and this filter was the best blend for versatility (3-11 stops) and price. I didn't see the benefit in getting an ND filter with a smaller stop range such as 3-5 or 7-11 etc. This ND filter covers the entire range in one package. And the adjustment ring feels high quality and has really good feedback when stopping down or up. I saw some people complaining about the grid pattern you get sometimes when stopping down on other ND filters, but I haven't experienced that problem. This ND filter has been nothing but perfect for me. I was able to shoot at 11 AM with with harsh light and overpower the sun with my flash for a recent shoot while staying under 1/250 sec. I definitely recommend this ND filter if you need to stop down for whatever type of photography you're into. The only issue you may have with this ND filter is trying to use a lens hood with the filter as they may not fit with one another.
