Class UV filter. Rich colors - no fogging or anything else. In addition, there is the protection function class. Only to be recommended.

This is the second time I am using a UV filter and the reason I bought it was for my upcoming trip to Bali where I am planning a long photo shoot. Being in the wilderness and in a country with strong sun rays, I figured buying a new UV filter to protect my lens would be best. Well this is a K&F product as is my ND filter and tripod which I recently bought because that's how I am and I like to buy a lot from one company. It came very well packaged and feels like a really good quality and it fits perfectly. I am very happy with the product and look forward to using and abusing it.

Economical UV filter I love making motorcycle videos and when I'm shooting on dirty roads I'm forced to use this type of filter to prevent a jumping rock from breaking my lens. Since they all produce UV rays, I leave you with a few photos where I've forced the appearance of the torch so you can see it clearly. Maybe it can be a problem for photos, but it looks cool in videos if you know how to play with it. The white has been yellowed a bit, giving the overall image a slightly warmer look. I hardly noticed any difference in sharpness between the filter on and off. For the price it is, it's great. I used to have one of the Hama brands and I would say this one is better.

Great protective lens. Really easy to install. Simply screw to the front of my EF-M 15-45mm f/3.5-6.3 IS STM lens. So much cheaper than buying one at the camera store. I don't have to worry as much about scratching my lens now. Didn't notice any difference in picture quality. The lens cap also still fits perfectly over it.

The protective filter came quickly and was well packaged. It is also packed separately in a practical plastic box, which you can use later if you switch between ND filters or UV filters, which I personally find very practical. The protective filter makes a neatly processed impression and can be easily rotated onto the lenses. I mainly use the UV protection filter as protection because I'm outside a lot. The lens glass is often splashed/covered with dogs and children, so I can quickly clean the protective filter with a cloth without worrying about scratching the actual lens glass. If the protective filter is scratched, you simply buy a new one instead of a new lens. I do have one downside though, if you take photos at night you have unwanted glare spots from the UV protection filter, so it depends on how you hold the camera so that it isn't too strong. When photographing during the day, with direct light (sun/lamp), I personally don't find the lens flare disturbing. It makes a clean processed impression, it protects my lens, which is my top priority, so I can recommend the UV protection filter. I find value for money very good.

Great lens filter at a good price. I didn't notice any blue tint or reduced image quality.

The fact that this thing is multi-coated makes it a million times better than any non-multi-coated variant. I've bought a different brand 77mm UV filter before and it's extremely horrible with specular highlights, especially in low light. Always, always be coated several times.

Attached is a photo I took with the filter on and it works fine. Take a look. I had no problems with it, it works, can't say it's there, what more can you ask for?

Good protection for the lens, UV does the job, you can put the lens cover back on. Right price.

bought the product for my Sigma 16 F1.4 with a diameter of 67mm to have the dual function of UV filter and lens protection. The product comes in a cardboard box, inside which there is a plastic box with anti-shock polystyrene. So I have to say that the packaging is essential but also suitable for later storage. The filter has written for the characteristics and to understand the assembly noise on the fly in case you can't see the thread in the dark. To use, simply mount it by screwing it onto the lens like all standard filters and you're ready to shoot. Before mounting I had tested the lens and noticed some reflections in rare cases. I must say that with the filter they are certainly limited, but I do not think they are 100% excluded. For this reason I have limited the rating to 4 stars, although probably no filter, not even according to well-known brands, could do better. Good overall, it looks solid and is better value for money on Amazon. Recommended.

got mine yesterday and said I would test performance with and without this filter. I have a vintage Minolta lens that was from my grandfather so it is very valuable to me and I wanted to avoid damaging it. As the title suggests, there is slight yellowing, vignettes, and a barely noticeable loss of sharpness that I can detect when viewing it on my computer screen, although the compressed images I've added may not fully show. Resolution of the original images. Let's break down what I found: The Yellowing - This filter has a slight yellow tint which makes sense, it's a UV filter so the shorter wavelength light might have trouble getting through. This isn't a problem for me as it can easily be adjusted and fixed in software after adding a little more blue, or this might get you better results in the field depending on your conditions The vignette - This is very easy though noticeable when looking at the same image with the filter on and off, again this is not a problem for me as it can be fixed or tweaked in software so that it is indistinguishable The sharpness loss - the sharpness loss is even at 400% barely noticeable, which is great. After that, if you just add 1 percent more sharpness, that's no problem for me. You have to view the photo at 200% resolution or higher to notice a loss, and even if you do see that, you have to look carefully. For what I paid for this filter, I'm happy to know that it doesn't affect my image in any way and that it acts as a shield, protecting my glass from scratches and dust. I will be adding more of these for my lenses and will not be forced to remove the filter to take a photo like I would with others. Great product, highly recommend!
