This filter appears very well made when attaching it to my Canon lens it screws in nice and securely. Straight out the box you get that impression from the box itself the protective storage box, the filter, lanyard and sealed cleaning cloth than comes with it.

The filter is super clear, something that really shows the quality different to my old cheap filters. I'm not sure how much of a different a UV filter actually makes given the coatings and number of lenses it needs to go through before reaching your cameras sensor. There is a lot of debate out there so will leave it the experts to elaborate further.

However I always have one to protect the expensive lens from getting scratched or damaged. This is not something maybe everyone needs but I have seen and heard of stories where the UV filter was sacrificed saving the lens. For example at a motor sporting event a stone was kicked up and smashed the filter but the lens was thankfully unharmed saving the photographer a lot of potential expense.

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.

Yes, it's adjustable, but with some EF Canon lenses it's impossible to take stock.

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 an EF lens to use with X-T2. Manufacturing is solid. The box is also fashionable. However, it seems to opt for a lens and STM systems like the EF 50mm f1.8 STM can't focus at all. Sigma's 70mm macro wasn't good either. Do you have any settings... In the present lens, the compact macro EF 50mm f2.5 could be used perfectly. Personally, only using this on an X machine is useful and I'm happy for now because it's better than buying an XF lens.

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
