I shoot photography semi professionally and needed a good CPL after watching YouTube reviews I popped on this for my canon t7 with EFS lenses it disappeared perfectly, stays on (sometimes to good can be a lil tough coming off), picture quality is great (I run manual always), hasn’t scratched or discolored yet it’s been like 2 years almost with near daily used mainly in the woods/nature, threads are okay that’s probably the only “2 complaints” if you’d call them such I have, first the lens cap (stock canon 58mm) do not hold onto the CPL so travel with caution and keep tabs on your lens cap or you’ll be buying more! And second it binds a little going on every now and then if they’d clean them up a shade and maybe get lens caps to hold tighter for travel this CPL would be and really is the best bang for the buck in my eyes! Yeah you can buy crazy expensive stuff but on a budget for non pro use definitely get you one! Once I finally do this one in I’ll be buying another. Oh and super important it comes in its own hard case for storage/travel with foam and it locks shut so it’s safe, I’ve had it in my camera bag and climber mountains and it’s stayed in the case no issues that’s definitely a plus i needed to mention.

Nice filter. Tested on a Canon 24-105 L lens. Lens cap fits fine, but the hood is a no go-either before or after applying the filter. Easy to use, good damping on the adjustments, stay where you put them, threaded on as good or better than any filter I've used. Biggest issue for me is having this with me when I need it. I expect this was designed by a waterfall guy. Can’t wait to try it when the weather breaks and I can finally get out to one. I had the best experience using a CPL when I was at Yosemite. Don't go there without one. This combo will be just the ticket when I return.

I used this filter on my Canon Rebel T7 with EF-S 18-55mm IS II lens and a size larger adapter. It works beautifully, crystal clear, screws on with ease. It comes in its own hard case with a cleaning cloth.

I have a Samsung NX 500 and the adapter fits perfectly, I've tried it with a Canon EF lens and it's perfect. It only works in manual mode

This adapter fits my Nikon J1 perfectly. I can use my Canon EF 75mm-300mm lens.

I have an old Canon 550D and some Lens. And now I've bought a Canon eos m100. I want to keep using my EF Lens. Then I buy adapters. This works perfectly and can autofocus very quickly.

bought this lens used for Canon EF. After two weeks of only being able to test it indoors for a short time due to bad weather, and I didn't really get enthusiastic results, I became skeptical... But now after the first real photo tour I'm completely enthusiastic... it shows its strengths especially at night. .. in the field of landscape, it could become my new favorite lens... I'm looking forward to my next vacation in the Orient

Perfect for my Canon EF-M 22mm, the Canon lens cap fits the filter perfectly, I wasn't expecting it!
