I love this variable ND filter. I'm using with a Canon R6 and a Canon RF 35mm F1.8 lens. Fit and finish is impeccable and and it's easy to rotate due to the tabs set at 180 degrees on the filter. Most importantly, I'm not detecting an cross-hatching, which is a common phenomenon on variable ND filters. Also, the lens cap fits securely on the filter, but you can't use a lens hood when using the filter. That isn't a big deal to me, but it's worth noting. This filter has stayed on the lens since I received it. Couldn't be happier - highly recommended. 5 stars.

This filter fits my Canon RF 800 f11 perfectly, even the lens hood fits on it, and vice versa. This is in contrast to the other reviews where people write that it is too thick. The optical quality is also excellent; I don't notice any loss of light or discoloration. A clear purchase recommendation from me.

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.

Bought the 67mm and 77mm of these.
Fits well, sturdy and protects your lens. (Canon RF 100mm f/2.8 and Canon RF 70-200 F/4)
No color casts or other deviations in the photos.

I have a crap filter. Discovered for me some time ago. I use this model on my Canon RF 24-70 2.8 to create a dreamy look. Of course, you can also fix this later by editing, but I like using the filter directly on the lens. The processing is impressive and the photos also look pretty. Because the price is also right, I'm happy to give it the full 5 stars. Of course, I also make a purchase recommendation.

Got this to combo with my Canon R5 and the nice all-around RF 24-105 4 L lens. Fits nicely, and the lens cap is secured. Its UV protection is a nice feature to have. It keeps my pictures free and clear from those pesky UV rays when taking pictures outdoors, especially at the beach. My kitty ended up being the celebrity for the day while we were getting some sunshine hehe. Definitely worth getting, especially for anyone doing outdoor photography with the 70-200 2.8 L lens or 24-105 4 L lens (77 mm diameter).
