K&F CONCEPT 77mm MCUV Lens Protection Filter High Definition Optical Glass | 28 Multi-Layer Coatings Waterproof Scratch-Resistant Ultra Slim UV Filter for Camera Lens (Nano-X Series) FV702

This UV protection filter is a nice, affordable way to protect a large camera lens. It fits securely and feels well made, with clean threading that goes on smoothly without any binding. The glass is clear with no noticeable impact on image quality in normal use. The multi-layer coating helps reduce glare and makes it easier to keep clean since smudges wipe off without much effort. Good value compared to similar filters from bigger camera brands. It does the job of protecting the lens while keeping image quality intact.

Great filter for protecting expensive lenses. My previous filter cost twice as much as this one and actually was a great filter but it didn’t have scratch resistant coatings. Over the course of a couple of years the lens cap actually scratched the old filter along the edges. This filter has the anti scratch protection the other one didn’t and it has anti glare coatings as well. I am unable to detect any difference between images taken with or without the lens filter. Some people prefer to shoot without filters in order to capture the best possible image. I prefer protecting a $1600 lens with a filter that doesn’t affect the image quality in any way I can detect. The filter came with a nice container as well as 3 micro fiber lens cloths. It’s a mid range priced filter and I’m happy with it.

I have these on at all times because they barely darken anything. Meaning high light transmission. I had to really look at some scopes to find a difference. I gave up and just assumed any light loss is meaningless. For sharpness, stopped down in the sweet spot with the new Sigma Art lenses, I can't tell a difference on my 42 mp camera. My Tamron 35-150 is pretty much perfect for 42 and 61 mp sensors, and its the same. Even the g masters my friends have shown it is pretty much the same with or without it. But, I can tell better contrast and micro contrast with landscape and city shape. It's basically dehaze in camera. And, a bit of clarity. I have had photography friends what I'm doing in editing to get clearer images, and it is using these and a cpl if I need to. Also, my lenses are expensive. They're insured but I would die if a front element got scratched. I work a lot of events and shoot video in weird places. Many years ago, I did actually trip and my Sigma 85 hit a rock. I didn't want to look. Luckily the lens was perfect and this filter took the hard scratch. Ever since, I buy knf concept nanox uvs for all my lenses. I spend the bit of extra money because the lens sharpness is intact. Color is all there. Dehaze in a filter. And, if a tragedy were to happen, I am out like $40 over $2,000. Or waiting forever for my replacement and insurance claim to go through.

I previously purchased this filter in a different size and was highly impressed. The slim design makes it almost unnoticeable, but the filter is still of high quality. The filter functions well. I believe this slim design also helps in the reduction of any impact the filter may have on photo quality, and color accuracy. The filter may also adds a layer of lens protection, in case of unfortunate situations like accidentally bumping into an object. This in addition to reducing dust on the lens itself. The previous iteration of the filter (67mm) proved to be very durable ( as it still sits on my lens). My most recent purchase (December 2025) had to be replaced, as it apparently spontaneously shattered. I discovered this when I was retrieving my camera from its bag (Lowepro), and heard the jingle-jangle of broken glass. My lens cap was still perfectly attached, hence my befuddlement. Overall, a quality product, despite the unfortunate occurance.

Good neutral filter for outdoors

After using this filter for a couple months, I can say it was what I expected. Great packaging and Value for the money, no vignetting. It does the job, it lives on my lens.

Always enjoy K&F products! Works well as a first line of defense for lenses to protect against dust and scratches. Could not recommend more.

The K&F Concept 58mm MC UV Protection Filter is a standout addition to my camera gear. The 28 multi-layer coatings effectively reduce reflections and UV light, ensuring sharp, vibrant images without any noticeable color shifts or vignetting. The filter is constructed from high-quality Japanese AGC optical glass, providing excellent durability and clarity. Its ultra-slim design allows for easy stacking with other filters, and the ribbed aluminum frame ensures a secure grip for installation and removal. Whether you're a professional photographer or an enthusiast, this filter offers reliable protection for your lens without compromising image quality. Fit: Perfect fit.

Ik had hem nodig voor bescherming Van een Fujifilm 60mm Macrolens en door voor voldoet hij perfect. Goede kwaliteit en betaalbaar.

Genial, usado en un teleobjetivo 150-500 no aprecio diferencias entre llevar filtro o no llevarlo, quizás un ligerísimo aumento de contraste. Es muy ligero y un marco muy fino que no produce viñeteo (no creo que lo cause salvo un angular realmente extremo) hace que sea incomodo de roscar por lo fino pero es el precio a pagar.

Exactly as described, works really well! I love having a filter on all my lenses helps to safe guard the lense against accidental scratches
