This MC UV Lens Filter has been a great addition to my gear. I already had a CPL filter from K&F and it is around the same size. The build quality is good. It's super slim, feels sturdy and reliable, and no vignetting from what I saw.

The coatings on this filter reduce reflections and ghosting. I tried sunny and cloudy conditions and the filter worked great with both. It also works as a protector for my main lens. As a physical barrier against dust, dirt, scratches, and accidental bumps, it gives peace of mind.

Finally, it does include a lens cap and cleaning cloth which are nice. The cap fits securely and the cleaning cloth is just your standard microfiber. I would say this filter is a great value for the price you pay.

Lens cap in package easy to install + easy to use Filter and lens cap are made of high quality materials small and lightweight so you can carry and store them anywhere Lens cap is easy to remove/install + helps improve photos Cleaning cloth in package Lanyard Ring on the top is hard to move

The 'K&F Concept 67mm UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter with Lens Cap' arrived in a branded box.

The lens is in a plastic case for protection, it also serves to protect one side of the filter, whilst the opposite side is protected by the lens cap.

The filter was an easy fit to my Nikon P900 and as it is slightly wider than some filters I found it easy to unscrew after use. I would however recommend carrying a suitable filter wrench just in case.

It would be nice to see a cover for the side of the filter not protected by the lens cap a the lens filter with cap attached are stored in a cellophane envelope in the case, I suggest putting the filter/cap combination into the envelope with the lens cap the same side as the flap which keeps the adhesive as far away from the lens as possible.

It would be nice to see a protective cover for the second side of the filter, maybe something push on.

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.

This lens filter and cap are of excellent quality.

Great filter and lens cap. I'm thrilled

I bought this adapter to put a Ricoh 50mm 1.4 XR Rikenon in my Sony A7III, connected it to the first one, turned on the camera and it worked straight away

Works perfectly. The focus range is like the old SLR. The Ricoh lens creates a nice look with the S1R thanks to the adapter. Criticism: you could have installed a rubber seal towards the camera, but at this price I'd like to turn a blind eye.
