This K&F Concept Magnetic 58mm Lens ND Filters Kit is surprising good quality, everything from the packaging, to the storage carry case, to of course the filters! They fit my fuji xt2 stock lens perfectly. I do wish there is another GND filter in the kit. The magnetic filter snap on and off easily (but carefully!). I am not a photography expert but these seems great quality! I am very pleased with this K&F kit.

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 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.

always buy the 77mm diameter filters for my largest lens. I have 2 lenses with a diameter of 58mm and so I can save myself the "keeping in front of it" and can easily attach my 77mm with the adapter.

Fraction of the cost of a complete ND system. The craftsmanship is incredible. I own the 72mm and 58mm filters.

I bought a Helios lens 58mm f/2 M42 for use on the NikonD5600. I use it with no problems. Thank you very much.

Fits perfectly on a 58mm lens. No impairment of the picture. Good lens protection.

This is a diffusion filter for cameras. I have the variant for 58mm filter threads. The Black Mist 1/4 filter creates a more softening effect. It looks nice, but you really have to look closely to see anything. However, you can see it in a direct comparison. In any case, it's not "too much". The filter is well made and fits every lens and camera with the appropriate filter diameter. (I tested it on 3 different cameras)
