The filter threaded onto my camera lens without issue, and is very clear. The case that it ships in has some protective foam inside of it as well, and has gone directly into the camera bag for future use if the UV Filter ever needs to be removed for other filter installs.

This is the first time I have purchased a K&F lens protection filter. I have purchased other filters in the past and this one has met my expectations of a protection filter. I would purchase another K&F filter in the future.

K&F makes decent gear for the money I found and this UV lens filter is no different. In all honesty, this is extremely well made, offering a quality finish and the feel of a seriously expensive kit. I appreciate that the jury is out on whether or not a UV filter is needed and I have no real feelings on the subject. However, what I like is that using a UV filter prevents damage to my actual lens within reason. Okay, I understand that if I drop my camera off the back of a truck it won't survive, but this lens filter will prevent minor scratches and swarf. It also keeps my fingers away from the lens and because it's flat it's easy to clean thoroughly with a cloth. Overall a no-brainer for me. I always put a UV filter on my lenses immediately after purchase just to give a bit of protection and K&F has some great filters for absolutely reasonable money.

bought this lens filter because I was looking for a filter no thicker than 3mm that would fit in a new Haoge lens hood (which cannot take thick filters) for my X100V to protect the lens and the camera to make weatherproof. If you don't know anything about the new X100V, you need a filter that is weatherproof. After some searching for a 3mm thick filter I found this filter from K&F Concepts on Amazon. I was skeptical that it would only cost £5.99 and there have been some complaints of a color cast. However, I thought I'd give it up for the price. The box it arrived in isn't the best, but it did its job and the filter arrived unmarked. I held it over a white surface and I could actually see a slight shade of brown. However, I don't see any color cast in the pictures. If you hold the filter up to the light you can see a purple reflection. I have tried to show this in the pictures but there is some fading. It looks very similar to the anti-reflective coating you have on glasses - I don't mind that. Overall I'm amazed, it's actually a really good filter with good spread and no obvious ghosting — I shot in the sun yesterday and it worked really well. I've bought far more expensive filters in the past that weren't as good. Recommended — consider buying a second one as a spare!

Quality filter with good multi-layer treatment on each side of the glass. No flare-ups were detected. No difference in sharpness at 100 percent magnification. No change in color temperature. No problem screwing in the filter, the frame is practical and light. So you don't have to pay more to protect a lens...

I've seen better ones (more robust), but overall this is very well made and works well... I would buy it again if needed. Good afternoon and God bless you...Randall M. Rueff K9RMR

I purchased this to protect my lens since I am constantly shooting Real Estate. This UV filter is good quality and protects the lens. I highly recommend it. For consumers reading this, I am using Sony 10-18mm F4 with this product. It is clean Af and works like a charm.

Bought to replace a shattered filter after camera was dropped. Doesn’t seem to affect image quality any worse. Great value.

Straight from the box, what a wonderful product. Fit perfectly on my camera lens and clearly a very high quality product. Love it. I'll be sticking with K&F products for sure, best I've encountered in the market

I used to only buy the expensive brand-name lens filters, but I decided to give K&F concepts a try, and I’m so glad I did because they work great.
