Very nice standard filter set consisting of a UV filter (clear) and a CPL filter. The two filters come assembled and have a threaded metal lens cap on each end.

These are ultra-thin filters that are less likely to cause problems like vignetting at the edges. Very well made, with machined aluminum construction on both the filters and the lens caps.

The CPL filter is a bit darker than what I'm used to, so it's better for outdoor daylight shooting than indoor.

The UV filter is the best I've ever used, crystal clear with no bluing or other artifacts - perfect, 100% clear. I always keep the UV lens on my camera lens for protection since it is so clear. Works well with stacking additional filters.

The threads all work flawlessly and the CPL makes for smooth rotation adjustment.

Great deal on this starter filter set.

*Photos do not show the UV filter as it was on my camera at the time.

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.

I’ve been a fan of K&F Filters for some time now, and have come to appreciate the consistency and the quality of the brand. The majority of my lenses live their lives with a K&F Concept UV protective filter on their front element.

I have done enough testing of the transmittance and sharpness of K&F UV filters in the past that I now consider them a trusted brand; I feel confident in their quality. And that’s the point, right? In my opinion, they’re a trusted seller.

I needed a protective filter for a new lens I purchased, a 28mm; the ultra-slim frame of the MCUV filter is why it became of interest to me and the reason I ordered it. And for that reason, it worked out well; it doesn’t infringe on the image area. Therefore, it doesn’t introduce any vignetting.

UV filters have an efficacy when recording on film, even though some emulsions are/were formulated to be insensitive to UV light, but have no added benefit when capturing to a digital sensor. Modern digital sensors, unfiltered, record the entire spectrum of visible light, as well as portions of the spectrums of invisible infrared and ultraviolet light. In order to record only visible light, so photographs appear the way we see the world, digital camera manufacturers install what is called an IR Cut Hot Mirror filter over the digital sensor and its Bayer Array. Digital cameras sold without this filter are referred to as a “Full Spectrum Camera.” If you’re not sure if your camera is full spectrum, it’s not. Which means you don’t need to filter out UV light, it already is.

In the case of my digital imaging, I use UV filters to protect the front element of expensive lenses. And in that respect, the K&F Concept MCUV Filter provides protection for expensive lenses without impacting camera settings or image quality, in effect providing inexpensive insurance.

As I noted at the beginning, I’ve come to rely on the quality of K&F filters, and for the reasons that the seller asserts, but most importantly to me, the high quality of their AGC multi-coated, anti-reflective glass; AGC is a Japanese company and the largest manufacturer of glass in the world. Another reason I have confidence in K&F filters.

The filter is supplied with a lens cap, a lanyard for the lens cap, a high-quality microfiber lens cleaning cloth and a plastic storage case.

I have used a few K&F filters on my camera lenses and have never been disappointed with their quality or price. The UV filter is made of high-quality optical glass and leaves no color cast or other imperfections on my images. Put simply, what you shoot is what you get, just beautiful, clean images. This type of filter also serves a secondary purpose as a protective filter for your expensive lens. After all, it's cheaper to replace a filter than a lens, isn't it? Overall, I am very happy with my K&F Concept 46MM UV Filter Ultra Slim Japan Optics Multi-Coated UV Protection Lens Filter and have no hesitation in recommending it.

EVERY LENS SHOULD HAVE A UV FILTER FOR IMPACT PROTECTION. NOT THE BEST QUALITY BUT IT WORKS FOR A LENS I WILL ONLY USE 10-15 TIMES A YEAR. CANON R3

The UV filter is very well made, a slim metal rim with with a scratch free pane of glass.

There's a slight bluish tint when held at angle from the optical coating but is invisible in the optical train when in use and doesn't introduce any optical defects like extra reflections or chromatic aberration or astigmatism.

These filters always raise eyebrows to the point of parody, look at any video online about UV filters and read the comments.

Personally i am in the middle of the debate. I wouldn't use one permanently attached to my camera lens as your camera doesn't need a filter to filter UV but i would use one in a volatile environment like a beach where wind can blow sand to protect a lens from being scratched and for that, its perfect.

UV filters don't do much from an optical standpoint, but I sometimes use one to add a layer of protection to my camera lens. If I'm in a windy or dusty environment, I put on a UV filter. I also like to use one when it's raining to keep water droplets off my lens. It is much easier to remove and clean an inexpensive filter than to clean an expensive camera lens. I try to wear UV filters with appropriate diameters for the lenses I use. As far as I can tell, the mechanical and optical quality is good. The filter screws smoothly onto my Nikon lens. This provider offers a variety of filters. The pricing seems very reasonable

UV filters don't do much from an optical perspective, but sometimes I use one to add a layer of protection for my camera lens. If I'm in a windy or dusty environment, I put on a UV filter. I also like to use one when it's raining to keep water droplets away from my lens. It is much easier to remove and clean a not too expensive filter than to clean an expensive camera lens.
