Really well made and works perfectly when I want to stop down outside. Using on a new Fuji X-T5 and a Fuji 18-55 to control the exposure. Very smooth and intuitive and the small machined aluminum knob is easy to find without looking for the rotating ring. For keeping the 180 rule outside at 24 and 30 fps with f2.8, it works perfectly. I wouldn't use it for the darkest portions since it does create a star shaped fringe at the dark limits. Otherwise, works perfectly for what I need.

This is a good size for the 55-250 lens. It is made of high quality material and feels strong and durable. I like this brand--they always seem to have good quality products. This lens hood should be great for keeping out side lighting glares and also for a little bit of extra protection on bumping the lens.

I bought this filter for my EF S 55-250 IS STM. Fits perfectly.

Bought to protect the Canon 18-45 RF-S lens. Optically very good. I see no degradation in image quality compared to the lens with no filter attached. Good fit but note that it's slightly wider than the lens barrel so the EW-53 lens hood gets a little tight over the top, but it goes over the filter... easy! Because of this, I have chosen to leave my lens hood in place full-time, rather than taking it off and inverting it for storage.

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.

From hell! Solid and well designed, my age 18-55 fits perfectly! The only thing missing is a fully automatic version and that would be Nerdasm ;-)

Have (as I'm sure most) no comparison to the Canon original adapter, which costs about 2-3x as much. The adapter works as expected for me in connection with a CANON EOS M100 and a Canon EF-S 55-250mm, I don't know what the original should be able to do better. Autofocus seems slower than with the EF-M standard 15-45 kit lens, but is sufficient for my needs. Covered the range from 15-250 inexpensively. Can't imagine that I noticeably miss the missing range between 45-55. Snaps in perfectly on both sides, sits firmly without misaligning in any way. It seems to me that it is built a little unnecessarily too deep, but I don't know whether the distance has to be like that for optical-physical reasons?
