Features
- Dual Functionality: This UV filter serves a dual purpose - absorbing UV rays and reducing blue tones caused by UV, ensuring picture-perfect clarity and color. Plus, it acts as a shield against dust and scratches, extending your lens' lifespan.
- Premium Optical Glass: Crafted with imported Japanese AGC glass, this filter guarantees razor-sharp imagery while preserving the authentic colors of your photos.
- NANOTEC Coating: Featuring 28 multi-layer coatings, including hydrophobic and scratch-resistant properties, this filter boasts an impressive 99.6% light transmission. This minimizes reflections from both the environment and the filter, providing true-to-life images.
- Telephoto-Friendly: With its ultra-slim 3.3mm frame and double-side polishing technology, the K&F Concept HD UV filter ensures clear imagery even on telephoto lenses, with no vignetting.
- Compatibility Note: Ensure a perfect fit by verifying your camera's lens thread size before ordering. The lens thread size is indicated by a "" (diameter) symbol followed by the size, such as 43=43mm lens thread size.

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.

Unlike some people I believe that a UV filter is a must on a lens for the protection it provides and for the ability to decrease atmospheric haze and glare. But having said that I also believe that the filter must be of high quality with good coatings so that it does not negatively impact your photos. I think that this filter meets these requirements. I have run some simple test taking the same photo with & without the filter and see no negative impact from the filter. The filter is also a good quality filter from a construction perspective and I see it lasting and providing a useful function for a long time, and for a good price.

Noticed that my existing 77mm UV filter (not a KEF branded filter) had a mark on the surface just before a trip. Quickly placed an order for the KEF Nano-X series MC coated filter yesterday and it arrived today. Have used KEF filters before and liked their quality and value for the money. The Nano-X series has all the specs I was looking for (Nano coated, mc, quality glass, and ultra slim). The ribbed styled ring aids in easier install and removal. Didn't want to spend more money on similar specs in other filters with no noticeable difference in picture quality. Rated 5-stars. Update: Decided to purchase a second one (77mm) for a new lens I just brought (Nikon 24-120 Z). Great product!

Best bang for the buck. Using with Sigma f/1.4 16mm. The absolute best is from Breakthrough Photography. Be ready to spend 4-8x for marginal improvement in IQ.
