have always put a UV filter on my lenses to protect the front element of the lens and now all of my lenses come with K&F UV filters. The fit, finish and quality have always been good. I also like that this one came with a lens cap as I have lost a few over the years. That will be a nice backup. The bonus lanyard is nice too.

The K&F Concept 52mm MC UV lens protection filter has no image degradation and fits perfectly on my Canon lens. It comes well protected with a lens cleaning cloth that can clip the lens cap. It's great to finally have dust, scratch and UV protection for my lens with no image quality issues at a very affordable price.

Overall, a pretty good lens filter. I haven't noticed much image degradation at all, and the lens cap seems to stay on well. I bought it to replace the old lens cap on an older Nikon lens that didn't have velcro fasteners in the diameter of the lens (just on the outside). It's a big improvement, and the protection the UV filter provides is great too.

I generally don't like putting bargain filters on a $5000 camera/lens, but I wanted to try this level of K&F. At first I was impressed with how thin and light this filter was compared to other filters I have. After taking a few dozen images in various scenarios with light, darkness, sun, and shadow, I was impressed by the fact that I couldn't see any loss or glare that some cheap UV filters cause. You only want $30 for this model, and considering how well it worked, I call that a bargain.

don't see any image degradation. The lens cap is a little harder to handle than other lens caps, but nothing to worry about. The lanyard and cleaning cloths are also some nice extras.

I got this for my Canon RF 15-35 and it works great! No noticeable difference when shooting and it has the added benefit of being threaded so you can put a polarizer or ND filter on it.

The UV lens is solid. I use it when hiking to ensure the lens has an extra layer of protection. There is no negative impact on the photos after taking photos with the camera on. The only downside I would have is that it can be difficult to remove sometimes. Other than that, it is a solid product as is usual with K&F products.

Purchased for my daughter who is a photographer. This is her favorite brand of filters so she loved getting a filter as a gift. She says these are the best filters on the market and will not use any other brand.

have been a fan of K&F Filters and many of their other photography products for some time and have come to appreciate the brand's durability and quality. Most of my lenses live their life with a K&F Concept UV protection filter on the front. I have sufficiently tested the transmittance and sharpness of K&F UV filters in the past, so I now consider them a trusted brand. I am confident in their quality. And that's the point, right? In my opinion, they are a trustworthy seller. I needed a protection filter for a 24mm-70mm zoom lens I recently purchased. The ultra-thin frame of the MCUV filter is what caught my eye and the reason I ordered it. And for that reason, it worked well. When the lens is set to the widest focal length, 24mm, the Ultra Slim Filter does not affect the image area. Therefore, it does not cause vignetting. UV filters are effective when shooting on film, although some emulsions are/have been formulated to be insensitive to UV light. However, they offer little to no additional benefit when capturing with a digital sensor. Modern digital sensors record the entire spectrum of visible light unfiltered, as well as portions of the invisible infrared and ultraviolet light spectra. To record only visible light, so photos look like how we see the world, digital camera manufacturers install what is called an IR-cut hot mirror filter over the digital sensor and Bayer array. Digital cameras sold without this filter are called a "full spectrum camera." If you're not sure if your camera is full spectrum, it isn't. That means you don't need to filter out UV light, the manufacturer has already done that for you. In my digital imaging, I use UV filters to protect the front element of expensive lenses. And in this regard, the K&F Concept MCUV filter offers protection for expensive lenses without affecting camera settings or image quality, thus providing cost-effective insurance. If it happens to offer an additional UV filter, that's a bonus. The physical properties of the filter are, without exaggeration, its almost feather-light weight as well as the faceted chinas around the perimeter that provide a good grip. I use a 67mm — 62mm graduation ring for the filter. The thread on the front of the filter provides sufficient depth for the secure attachment of the ring and thus the associated stacked filter. The K&F front lens cap that comes with the filter is equal in quality to, if not improved upon, the OEM lens cap that came with the lens. The clamp levers are easy to use, firmly spring loaded and ensure a firm hold of the filter or lens. As I mentioned at the beginning, I have come to rely on the quality of K&F filters for the reasons the seller claims, but most importantly for me, the high quality of their multi-coated AGC anti-reflective glass. AGC, a Japanese company, is the largest glass manufacturer in the world. Another reason why I have confidence in K&F filters. The filter comes with a lens cap, a lens cap lanyard, a high-quality microfiber lens cleaning cloth and a plastic storage case. K&F Concept offers good value for money and doesn't cut corners.

Not much to say here other than this filter is a winner for the asking price. The filter itself is lightweight and has a deep knurl between 2-4... and 8-10 (depending on the clock setting). It comes with a hard case for storage, a cleaning cloth, a lens cap and a strap for the lens cap. Everything you need to get started, it's a complete set. If you need a UV filter, you can't go wrong here. Recommended.
