This is a fantastic filter. I was hesitant to buy this for my Kowa TSN-88 spotting scope because I wasn't sure if it would fit, if it was good quality, or if I really needed it. I was testing my scope on a hot, cloudy day and couldn't quite make out the street sign two miles away on the hill. I put this filter on and things got a little clearer, the mirage a little less, and I could actually read the sign (Lane Ends Merge Left). Very happy with this and I didn't have to pay double or triple for the Howa, B&W, or Kowa filters. The only downside is that the scope's sunshade won't extend with this filter in place, but I imagine that would be the same with any other filter as well. Read more

Muy buena calidad del producto. Tengo otros productos de esta marca y da excelente calidad. No produce efectos no deseados con el enfoque. Utilizo un lente 180-600mm, con diametro de 95mm, habia comprado antes unos filtros más baratos, pero no fueron de buena calidad óptica, lo cual en fotografía no es deseable. La foto del colibrí es con los primeros filtros comprados, la del pinzón es con K & F concept. La imagen habla po sí sola Read more

I am new to photography so my experience is limited. The photography store I go to told me to be careful with lens covers as they have had a few people come in with issues with their camera not working and tracing the issue back to a bargain brand lens cover that was bought online. I showed them this one and they said it should be good to go. We have now bought two different sizes for different lenses in this brand. Acquiring the first one in December and the second in February. Both work well and help with stage lighting glare. Read more

I own half a dozen K&F Filters and have been impressed with their quality. For their price, these filters are top notch and you would be hard pressed to find higher quality filters at these price points. I recently purchased the 95mm UV protection filter. After using it for a week or so, I had no complaints about image quality. Unfortunately, a relatively minor bump to the filter caused it to come apart. I contacted K&F and they responded immediately, working to resolve the issue and sent me a brand new replacement filter. They were incredibly responsive to my emails. 10/10 for customer service. Despite the filter coming apart, I do not have any concerns about the quality of K&F's filters. I look forward to receiving the new one and anticipate it will be on my lens for a long time to come. And if for some reason there's an issue, I know K&F will work to resolve it quickly. Read more

I was looking for a good filter that would be as good as my Zeiss T* UV filter. I know this is not a fair comparison, but even the Viltrox filter comes close to my Zeiss T* UV Filter. First off, I used a basic UV test card to compared if this actually removes UV light. Doesn't do it at all. My Zeiss filter does remove some of the UV when testing it with my UV test card, so I wanted something similar. After ordering a few brands of UV filters, I picked this one to see if it was any good. While it does have good anti reflection it doesn't remove any UV light at all. It doesn't affect the image at all or color but it doesn't remove any UV light. I even used a UV light to see if it does. Nothing. Nice packaging but I guess that's what the extra cost is for. I wouldn't recommend it for those who are looking for an actual UV filter. Read more
