95mm UV Protection Lens Filter - HD Ultra Viloet Filters Scratch-resistant Ultraviolet Protector Filters for DSLR Cameras (Nano-X Series)

I always put a filter on my lens for protection, and K&F are good quality and competitive price, and when I get more lenses I will buy again.

Like to have a filter on every lens to protect the expensive glass. This feels good quality and adds very little in terms of overall size t the lens. The thread of the filter did seem a little fine and it did take a couple of attempts to attach to the lens but once on it feels secure

I cannot fault the glass, it's top draw and does what it says on the tin. The rim looks and feels great. However, the thread is fine but not up quite up there with the smooth filters from Japan, Hoya and Nikon. Just be careful initially hand threading, it's a touch of grind. I would probably add a bit of lube on thread with hindsight. The biggest kicker is my lens cap no longer fits my Pentax 35mm F2 with the filter attached(it's the type where lens cap edge covers over the side of the filter rim and not flush with just the top edge of the rim, so depends on the lens cap design). Further inspection shows the girth has put on enough fraction of a mm compared to the lens body to make the original old lens cap obsolute. I'm guessing the slim depth design means a compromise on the extra width. You get what you pay for as they say. Still, good value if you can work around the lens cap issue and thread grind doesn't put you off.

Amazing quality. Product came in a very thoughtful wallet that suggested quality. First impressions do count. I bought the 105mm filter as I was concerned that the Sigma Art 105mm was too vulnerable for my clumsiness. Clarity looks wonderful.

Really excellent filter. Fits under JJC auto lens cap for Leica dlux 8

K&F products are always top tier and this UV filter works like magic it doesn’t change the colour on my pictures or videos which makes it even better, also I don’t ever see myself ever using a lens without protection and k&F do a great job making these. Easy to use and provides good protection. I’ve been using K&F for a long time now and they’re the only ones I trust when it comes to filters and other items that are both expensive and budget friendly

Good quality , well worth the money

I’ve been using this filter for over 3 months and so far when taking pictures I haven’t noticed any glare . The quality is also on point, very durable metallic body. Recommend this product!
