That's 100% the reason to buy one of these. Think of it like a screen protector for your phone. scratched? throw it away, buy a new one. Dirty or watermarked by the rain? wipe it off The point is that your expensive glass stays safe underneath.

I needed a UV filter for my Canon 24-70mm lens. The filter is good fit. The quality of the glass is outstanding. The filter comes in a plastic container which provides protection when I take the filter off lens and store in my camera bag. This protects the filter from scratches when not in use.

Not a bad little filter, but did experience a weird fogging on the glass when I first installed this filter but after 3 with a microfibre cloth and lens cleaner seemed to have sorted the problem. Picture quality is ok but compared to my Hoya filters it’s not as sharp, but it’s marginal to honest.

New camera, new lenses so I needed the extra protection offered by a UV filter. I trust the brand so bought this one (and another size too). Happy with my purchase.

Didn't want to pay a lot for a UV filter but still wanted one in my camera bag for landscape photos...read other reviews, came across this brand. Can't complain about the quality, it does the job, no problem reducing the image quality and my lens is easy to put on and take off. Great value for money

I think that this is another great offering from K&F Concept, the filter is blemish free and fits perfectly on the lens, with the thread making it a quick process to put on and remove if required. I have bought several Lee and Cokin filters in the past and this seems to offer just as good service as the more expensive brands

Very Good Protection for my Sony lens . Need to order another one for my second mainly used lens. Very happy with the purchase .

So far so good. Time will tell

got mine yesterday and said I would test performance with and without this filter. I have a vintage Minolta lens that was from my grandfather so it is very valuable to me and I wanted to avoid damaging it. As the title suggests, there is slight yellowing, vignettes, and a barely noticeable loss of sharpness that I can detect when viewing it on my computer screen, although the compressed images I've added may not fully show. Resolution of the original images. Let's break down what I found: The Yellowing - This filter has a slight yellow tint which makes sense, it's a UV filter so the shorter wavelength light might have trouble getting through. This isn't a problem for me as it can easily be adjusted and fixed in software after adding a little more blue, or this might get you better results in the field depending on your conditions The vignette - This is very easy though noticeable when looking at the same image with the filter on and off, again this is not a problem for me as it can be fixed or tweaked in software so that it is indistinguishable The sharpness loss - the sharpness loss is even at 400% barely noticeable, which is great. After that, if you just add 1 percent more sharpness, that's no problem for me. You have to view the photo at 200% resolution or higher to notice a loss, and even if you do see that, you have to look carefully. For what I paid for this filter, I'm happy to know that it doesn't affect my image in any way and that it acts as a shield, protecting my glass from scratches and dust. I will be adding more of these for my lenses and will not be forced to remove the filter to take a photo like I would with others. Great product, highly recommend!

Good protection for the lens, UV does the job, you can put the lens cover back on. Right price.
