77MM UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter
SKU: KF01.K77
My Olympus 60mm Macro lens now has this great filter attached. The lens comes with no hood, a poor front cap and obviously no filter. This one is now aboard together with a decent front cap and a third party lens hood. 46mm is a bit small and fiddly, but this has a really good knurled ring that is easy to grip. The thread is also very smooth and positive. The colour balance is undetectably different, so does not interfere when picture taking in well lit close up situations. I love the enhancement of this brilliant lens. Ricky.

Just got a new lens, needed a 77mm filter to protect it. I'm not going to sit and tell you this glass is better than some other glass. I just got it, and I'm not an optics expert.
But, I will tell you the packaging was beautiful, the filter case- one of the nicest I've ever seen. It is circular- and holds multiple size filters with grooves in an internal bracket. So much nicer than the big clunky square filter boxes I've got from other brands.
But- the killer was the filter being so thin- and that it has 2 areas that are gnarled, for you to grab it- while the rest is smooth- a really nice feature.
Seems right at home on my Canon RF24-105/4 L IS USM.
Didn't notice any difference in speed of focus- or aberration- but, again- I'm not a lab.
I'm pretty happy with this brand. Didn't expect to be.

The important thing with filters is that they don't degrade image quality, and also that they have no colour cast or flaring on final images.
As a pro photographer these are more important for me than most, and luckily these work perfectly.

I've used a few K&F filters on my camera lenses and have never been disappointed with their quality or price. Made from quality optical glass, the UV filter leaves no colour cast or other imperfections on my images; put simply, what you shoot is what you get, just nice, clean images. This type of filter also serves a second purpose as a protection filter for your expensive lens. After all, it's cheaper to replace a filter than a lens, isn't it?
Overall I'm very happy with my K&F Concept 46MM UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter and have no hesitation in recommending it to others

Gave it a good exercise in Sri Lanka, day and night. Results were excellent. Why pay more?

I am usually against UV/haze filters as I am concerned about their effect on image quality. However, I plan to use my Sigma 150-600 DG DN Sport (Sony E-Mount) in pretty harsh conditions such as coastal bird photography, surf photography, and sports. So, I caved and purchased this filter to provide protection for the lens front element.
However, given that this K&F filter would probably be considered "mid-tier" in terms of price, I wanted to test if it in fact had any effect on image quality. The attached image of a $20 dollar bill was taken under the same exact circumstances - 600mm at ISO 100, tripod with OS off. As you can see from the screenshot taken in the compare view of my photo editing software, the image on the right (with filter) is clearly sharper with better contrast.
I'm shocked! I had fully expected to remove the filter when I wanted a better image. Now I can leave it on 100% of the time, and easily wipe off any splashes or dust without worrying about scratching the front element. Strong recommend!

Both lenses are Sigma lenses with 2 different brands of UV filters on them. The lens on the left is my 150-500mm with a filter made by another brand. The right is my 150-600mm lens with the K&F filter. The lens on the left looks a little hazy, while the K&F filter does not.
Does not decrease image quality that I can tell. You can feel that it is weather sealed, but I'm not testing it to see if it truly is.
Comes in a plastic case
So far, no complaints.

Very high quality filter and does exactly what it's supposed to do - does not affect image quality
