The UV filter is intended to protect a very old lens from the last century from scratches caused by sand, etc. A cool side effect is that the object now looks a bit more modern and open-glazed from the front :-)

It removed reflections and got a good rich color with no excess blue. The only problem is that the flower aperture lens hood causes vignettes when the filter is on!

le filtre UV en plus d'éviter la dominante de bleu c'est un très bon moyen de protéger la lentille de votre optique. Les objectifs sont traités multicouches et leurs surfaces sont fragiles.

I haven't had any strange aberrations with this filter. Fits snug and appears to give ample security in the case the lens is set down too hard.

As soon as you open the package you immediately understand that we are dealing with a quality product because it comes with a very nice rigid packaging and the UV filter is sealed separately inside, all for 8€, what can I do say more? I've been trying it on Lumix 25mm f/1.7 for a week and it's perfect: it doesn't change color and saturation at all, for me it's 5 super deserved stars.

I've bought photo material from K&F in the past and have never had any problems. I bought this UV filter for my new 82mm diameter Sigma mainly to protect the lenses from dust and scratches. Easy to assemble, well built, it comes well sealed in a box. It is worth the price paid.

bought this filter for protection against my very sensitive Sigma lens. The requirements I was looking for were therefore: excellent transparency, anti-reflective treatment, good anchoring thread. I put my choice on this filter, which mainly depends on the price. I have to say I was delighted with it. Excellent transparency, tight and stable thread without any backlash, aluminum frame body, and in addition, anti-reflective treatment is very effective, no vignetting phenomenon or chromatic aberration. Arrived in a practical case, closed in a plastic blister and well packaged. Very happy with the purchase even considering the price. I highly recommend it.

Do not reduce too much light entering the housing. I only use it as a protection for the front lens
