have used this filter on one of my 77mm lenses with good results. Likes: - The filter causes no apparent loss to image quality or contrast. - The filter screws on the lens smoothly. The added texture on the filter edge makes it easy to put on and remove. - It comes with a lens cap and case. My OEM lens cap fits on the filter as well. - The filter is selling for $15.99USD as of this review and that is a very good price for glass of this quality.

As with other Lens filters I have received from this brand, this is a top notch uv filter. It doesn't distort your image and mount easily onto my 49mm lenses.

Protects expensive lens.

These filters seem fine for the basic cover-your-lens protection job that most people need. They cost much less than the more known brands. For my purposes, and I've been using pro grade gear for years, they work fine.

K&F Concept has become a go-to brand for quality yet affordable gear for photographers, and this filter lives up to those expectations. The build quality is impressive for the price. It comes in a plastic storage box with a solid lens cap, a lens cap tether, and a cleaning cloth, all for under $16. The primary need for a UV filter is to protect your expensive lenses from dust, dirt, scratches, and potential damage, while also cutting down on the blues a little. While this filter from K&F is their basic UV model, it does the job well. It's not waterproof or scratch-resistant, which explains the lower price. They offer more expensive options like their Nano-X series, but those come at a higher cost. Cheap filters can often cause flaring or ghosting in your images when there's a strong light source and can also affect autofocus and image sharpness. However, I haven't noticed any of those issues with this filter. The clarity of the glass seems excellent, and my shots remain crisp and clear. The ultra-slim design of this filter ensures there's no vignetting, even when used with wide-angle lenses, which is a plus for landscape photographers like myself. The included lens cap is also a nice touch; it snaps on securely and feels better than the ones that came with the lens. Overall, this is a solid choice for photographers looking to protect their gear without breaking the bank. It combines quality, affordability, and reliability, making it a valuable addition to any camera bag.

OK, I didn't look carefully and thought I was getting only a UV filter at a pretty good price point. But it also came with a lens cap, a microfiber cleaning cloth, and a lens cap strap so you don't have to put the lens cap in your pocket, so it was actually an excellent price point. I use a name-brand Japanese camera with an autofocus macro ("micro") lens, and the lens cap strap is long enough to go from the base of the lens (against the camera body) to the tip of the lens. For a different lens where the focusing ring wouldn't get in the way, i.e. the fifth picture on the Amazon web page, the strap is of course longer than necessary but that wouldn't be a negative. So far the lens cap is holding up; even the name-brand products that match the name-brand camera wear out and need replacement eventually. The anti-reflection coating is free of voids and the threads were smooth. I like to include negatives in my reviews, however I don't have anything bad to say about this product.

got this K&F filter as a review item. I was so impressed with the quality of this product, that I have bought several more in other diameters. The packaging, the plastic filter case, the included accessories... all phenomenal. Its a UV lens filter. So there is not much overall effect on the resulting images. But everything about this product was great. The included lens cap was better than the one that came with my lens. I especially like the little orange wrist strap that was included. There is also a cleaning cloth. Its a very nice product. They include all of that stuff for such a great price. Excellent.

Feel so much better having an extra layer of protection on the glass. Fit was perfect and lens cap is top notch with no bump-opens like my Canon did regularly. Will definitely look to K&F for future filter needs.

This is a nice set that works well with my Tamron lens with a 67mm filter. It screws on easily and provides additional protection at a reasonable price. It comes with a lens cap and tether which is handy. A nice UV filter that does the job well!

Excellent value for an essential filter for your camera. UV filter is made of quality glass and does not affect the quality of the image. Recommended.
