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.

Nowadays, the biggest advantage of a UV haze filter is to protect the front element of the camera lens. There's also haze correction, but the need for film for blue reduction isn't the case with digital cameras. The bigger reason is that today's post-processing software can filter as much haze as the photographer desires, which no UV filter can do. The need for protection is real. Even if it means keeping the front elements of your lenses from getting dirty or splattered, these filters play a role. I was wearing this filter when I made a misstep and splashed into a small river that soaked the camera. I felt a lot better about my clumsiness knowing I wouldn't have to face the delicate chores of lens cleaning when I got home. However, a filter in the light path must be of high quality, otherwise the image will be degraded. I'm far from having a lab to test glass here. The best test I could think of was easy. I would take an identical picture with and without the filter and then compare to see if I have any issues. Yes, it's raw, but it's what I have. Please see the included image. To create this, I set the camera on a tripod, set the exposure manually as a best estimate, and then took two pictures — one with and one without this filter. I took the RAW images, randomly cropped a portion of one and pasted onto the other. Both are labeled. I then compared the two and focused on the area where they merged. I drew a black line at the approximate location of the join. I didn't do any post-processing. These are the RAW (DNG) images straight from the camera, converted to JPEG just for posting here. I did my best pixel peek on both images and didn't notice any distortion from this filter. In other words, it does exactly what I want it to and has now earned a spot on my lens.

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 image quality is exactly the same without any problems. It blends into the camera and protects your expensive lens from damage. To assemble it, you turn it in circles several times to tighten it. No instructions are provided, but pretty much self-explanatory. More information on their website. There is also a 1 year warranty period if you register the lens from the date of purchase. These can be replaced at a much cheaper cost than having to buy your expensive lens again!

This is a well built UV filter. I did this to attach a non-weatherproof lens with an internal zoom mechanism. A UV filter on the front provides extra protection from the rain for an upcoming trip. The anodizing on the metal ring appears to be of good quality. This and the knurling on the outer ring offer a very good grip when installing and removing. The threading corresponds to the thread on the lens cavity. The filter glass is crystal clear. I found no noticeable degradation between shots taken with and without the filter attached. For the same shot and lighting, my camera didn't adjust the exposure values between turning the UV filter on or off. This is a good UV filter for those of us who like a little extra protection for our lenses.

The threading matches the thread on the lens well. The filter glass is crystal clear. I found no noticeable degradation between shots taken with and without the filter mounted.

I was trying to update the UV filter on my telephoto lens and this looked like a great option. The glass is very clear and doesn't cause any problems or artifacts with my photos. It's a really nice UV filter for $20 (at the time of this review) and the quality and materials seem very good, especially for the price. I would recommend that!

The filter arrived well protected and appears to be of really good quality. I usually use Marumi, Hoya and B+W filters but this seems like a great and more affordable alternative (at the time of this writing). Feels light but good construction Nice ridges in attach/remove size. I installed it on my Tamron 28-75mm lens that I use on the Sony 7R III and after some test shots I didn't notice any distortion, flare or other negative effects. The sharpness was not affected either. Very happy with this filter so far. Protects the lens and doesn't seem to affect image quality. Will definitely try other K&F filters.
