Raynox RA-3721 Reviews

21-37mm Step-Up Ring is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Just what you need for the off brand cell telephoto lens Did you buy one of those telephoto lens for your smart phone? Did you find that there wasn't anyone on ebay or amazon selling filters to fit your lens? in fact did you did that your lens didnt even mark what size threads you have? That was me. And I needed ND filters. and they dont sell 21 (or 22) MM size filters. THIS PRODUCT saves the day! if you have a 22mm thread like I do, a piece of paper or piece of tape on one side of the thread will do the trick,.
