The UV filter has a high-quality and clean finish. I really like the blue-purple reflection and it really makes a difference. I didn't notice any changes in image quality, but there could be a slightly different, increased lens flare. If you like the look, you will be satisfied with the filter. In any case, I can recommend it as protection for the lens!

I almost returned it when I found out my lens came with a complimentary $50 Sigma lens UV filter. The optics on it are wonderful, but I'm about to go to Niagara Falls and I imagine I don't want to marry my lens cloth.

I thought - why not just test them both under the sink before sending it back? So glad I did!

As if by magic, this K&H filter drains and all the water disappears. The free Sigma filter? It sucks the water! And it's hard to get off!

If you received a free high-quality UV filter and stay dry 24/7, no upgrade is needed. Do you value versatility in all weathers? Buy this now!

I'm really excited Great photos pin-sharp super good blue whether sky or water awesome. The workmanship is very solid, the packaging is also good, the whole thing makes a valuable, robust impression, I am enclosing a few photos.

This kit comes with all the filters you will likely need. The UV Filter is one you will keep on your lens to protect it from accidents. The other filters, Polarizer Filter and Neutral Density Filter are more specialized. The Polarizer Filter is basically used to reduce glare from reflective surfaces and make blue skies "more blue." The Neutral Density Filter basically balances exposure in high contrast scenes. Note that you never get something for nothing, and your mileage may vary. The set also comes in a nice storage case. I bought several of these sets and I highly recommend them.

UV filters in the digital age only make sense to a limited extent. I mainly use this type of filter as a protective glass for the lens, so that I don't have to worry about damaging the lens even on the beach or during somewhat hectic photo shoots. The protective function is achieved very well with this filter. The processing is good, the glass is clear and without inclusions. The filter edge is thin enough that there is no vignetting. The blue coating is a bit annoying. If the sun hits the filter unfavorably from the side, a blue shimmer is produced on the photos. Of course that shouldn't be the case. However, this phenomenon only occurs at very specific angles to the sun. But the value for money is good, so ⭐️⭐️⭐️⭐️

I bought the polarization filter to hide reflections on the water. Especially after my vacation on the water you realize that such a filter would have been practical. Use it on my Sony 18-200mm lens. Not ideal because polarization filters and telephoto lenses are not that good I particularly like it, but I personally haven't noticed any major loss of sharpness in the telephoto range with the filter. I also use the filter on a UV filter (can't get the UV filter down easily because the lens thread is slightly broken). Advantage of this is that you can get very good access to the filter in order to adjust or unscrew it. About the pictures (are not post-processed): As you can see from the pictures, the filter does an excellent job.The reflections from the water have almost completely disappeared. On the other pictures you can also see how the green rendering has improved significantly. So I can only recommend the polarization filter for the cheapest price.
