bought this for a rarely used camera. It's still a valuable collector's item that I want to keep in excellent condition and that means I had to protect the lens. I only have filters with the Zeiss "T" coating made of German Schott glass on the cameras that I use a lot because I think they are the best multi-coated filters I can afford, but I can't spend the money on them spend on a camera I rarely use. Any camera that is threaded to accept a filter deserves the protection that comes with a filter mounted in front of the actual camera lens. I would rather risk damaging the AR coating of a filter that can be easily replaced than risk damaging the actual lens on one of my cameras through cleaning and exposure to dust or chemicals in the air. This brand of filter came carefully packaged and the filter holder that comes with the filter is well designed and provides excellent protection for the filter when it is not on the camera lens as I am using a different type of filter. This filter has multiple AR coatings on both sides of the filter and after comparing the results of identical images taken with the same camera using this filter and one of my prized and now unaffordable Zeiss "T" filters, I can say I see no difference can the results. I'm sure an optical lab could document some differences, but in the real world I can't see any differences when comparing the test images I took with this filter and the Zeiss filters I've used. This design works so well that I am slowly replacing the older non-Zeiss filters I have on my older lenses and cameras with these newer designs.

This lens filter is wonderful!!! The clarity I get with it is amazing. I plan to slowly put these on all my lenses.

Filter feels great. Haven't used it often but fits well. Glass is made of high quality material.

bought this filter without the knowledge of the company. I still don't know anything other than what I've observed: it appears to be of quality construction, and most importantly, I took it out to shoot and the clarity and visual performance of my favorite wide-angle Nikon lens remains just as superb as always. So a quality filter at a very good price.

Super quality and always fair in price.

K&F makes some of the best UV filters for the price. The ring also contains grooves so you can easily remove the filter. I would definitely recommend it to people who have expensive lenses and want peace of mind.

Very good value for money, as a dash photographer I can't tell the difference between K&F UV filter and the one I bought on another camera and paid 4x the money.

this is awesome filter. picture quality remains perfect with the filter and great for protection you lens.
highly recommended

This is my go to filter whenever I get a new lense or notice that an old filter is starting to degrade. Great value for money and sharp pictures.

Fit as described - easy to install - packaged very well with storage case. Fast delivery.
