I have the 67mm on my Sony a7iii on my 85mm sony lens. It's so clear you don't even know it's on. The picture quality is the exact same without any issues. It blends in with the camera, yet saves your expensive lens from damaging. To assemble it, you turn it many times in a circle to tighten it on. No directions come with it, but pretty self explanatory. More information on their website. There's also a 1 year warranty period covered when you register the lens from the date of purchase. These can be replaced at a lot cheaper cost than having to repurchase your expensive lens!

While UV filters can improve your picture in some situations, most people buy them to protect their lens from splashes and dust without changing the image. This one seems good for that, it fits nicely on my sony 24-70 zoom lens and doesn't interfere with using either the lens hood or the original lens cap.

There is hardly any change in the amount of light that gets through to the camera and the UV filter can help to reduce atmospheric haze in long scenic shots and make the image a bit sharper.

This filter also has a water repellant coating, I haven't had to test this yet but if it works like the one on my glasses you won't have to wipe it if it gets wet. Any water that doesn't fall off immediately can be blown off with a hand blower so you don't have to touch the filter with a cloth.

Highest quality! Crystal clear. Smooth threading on lens with metal made ring... Thank you!

You never want to be without protection so its a good idea to always have an extra UV filter on hand! I have a couple others K&F including UV and polarizer and have no problem recommending. I saw no anomalies, flares or distortion. I would like brass mount but for the money these are perfect.

Today most of the benefit of a UV Haze filter is to protect the front element of a camera’s lens. There is some haze correction too but the film need for blue reduction isn’t a case with digital cameras. The bigger reason is that post processing software today has the ability to filter as much haze as the photographer wishes which is something no UV filter can do.

The need for protection is real. Even if it means keeping your lenses’ front elements from getting dirty or splashed, these filters play a role. I had this filter on when I took a misstep and splashed into a small river soaking the camera. I felt a good deal better about my clumsiness knowing that I’d not have to face the delicate job of lens cleaning when I got home.

However, a filter in the light path needs to be of high quality or it’ll degrade the image. I am far from having a lab where I can test glass here. The best test I thought up was simple. I’d take an identical image with and without the filter on and then compare to see if I caught any issues. Yes, it’s crude but it’s what I have.

Please see the included image. To create this, I placed the camera on a tripod, set the exposure manually as a best guess and then snapped two images – one with and one without this filter. I took the RAW images, arbitrarily cut a chunk from one and pasted it on the other. Both are labeled. I then compared the two concentrating on the area where they were joined. I’ve drawn a black line at the approximate location of the join. I did no post processing of any sort. These are the RAW (DNG) images directly from the camera only converted to JPEG for posting here.

I did my best pixel peek at both images finding no distortion whatsoever from this filter. In other words, it does just what I want and now has earned a place on my lens.

A UV lens is one that I recommend everyone have in their kit, especially if you like in very sunny but windy climates like I do. It really does help protect my lens from the debris flying around and just things in general. Photography isn't a cheap hobby/profession so taking a few dollars to invest in some protection is necessary. The fit of this is very tight, at first I didn't think it would fit properly but I just had to screw it on and off a few times before the threads slipped on with ease. These aren't super expensive which is great, but still do the job.

As expected, easy to assemble. No problems.

UV filters don't do very much from an optical standpoint, but I sometimes use one to add a layer of protection for my camera lens.

If I am in a windy or dusty environment, I pop on a UV filter. I also like to use one when it is rainy to keep water droplets off my lens. It is much easier to remove and clean a not-to-expensive filter than it is to clean an expensive camera lens. I try to carry UV filters of appropriate diameters for the lenses I use.

Mechanical and optical quality are good as far as I can discern. The filter threads smoothly onto my Nikon lens.

This vendor offers wide variety of filters. Pricing seems very reasonable

If you look at the photos you can see my Canon lens with major scratches. This is what happens when a guest hits your camera with a big ring! The lens still works but the value is gone. This is why you need a little extra lens protection when shooting. I can't believe I never purchased a filter for this lens. Just like driving, it's the other guy that will cause an accident and you end up paying the price. In the other photos, you can see a side angle of the new filter. It is thin and fits this, Sony, 24-105 just fine. The Lens hood fits over the filter and the lens cap works without any issues. The filter itself looks like very high-quality glass.

I put something on all my outdoor lenses to protect them, and I like to use a UV filter to cut a little of the normal haze shooting in beachlike settings. I usually use something pricier, but decided to try the K&F Concept 52mm MC UV Protection Filter.

It arrived in a slightly wider than normal filter box. The box was slightly larger because the filter was packed in a latching plastic box with foam protecting the filter from damage. I looked at the filter under a magnifying light, and it was flat and smooth with no scratches or oddities. It fit my 45-150mm lens perfectly, and it really is a low profile filter. It doesn't seem to affect lens sharpness, doesn't affect clarity, and I'm pleased with it.

I'm quite happy with this UV filter. Is this filter as good quality as one of my $50 B+Ws? Possibly not, but on the other hand, the B+Ws cost over twice as much, and you'd have to be a pixel peeper to notice the difference in image quality. Viewing my pics at 100%, I'm satisfied.
