K&F Concept 86MM UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter (Nano-K Series)

As someone else has already discovered there is a peculiar effect when using this filter and one that I have never experienced in well over 30 years. There is a greenish/blueish' streak' for want of a better word under certain light conditions. I learnt from the other reviewer and purchased a Polaroid UV Filter. The problem was solved immediately. I can only assume it must be to do with the coating. Would have liked to given a higher star, but I have to be honest. Not that impressed - sorry.

K&F do make some decent gear for the money I've found and this UV lens filter is no different. Honestly this is supremely well made with a high quality finish and a perception of a properly expensive bit of kit.Now, I do appreciate that the jury is out on whether a UV filter is or is not needed and on that subject I have no real feelings. What I do like though is that using a UV filter prevents damage - within reason - to my actual lens. Okay, I get the fact that if I drop my camera off the back of a truck it's not going to survive, but having that lens filter does stop minor scratches and abrasive dust. It also keeps my fingers away from the lens and being flat easy to clean thoroughly with a cloth.Overall a no brainer for me. I always put a UV filter on my lenses immediately upon purchase simply to add a bit of protection and K&F do some great ones for entirely reasonable money.

There are some very poor cheap filters, but not these these excellent K&F filters, at exceptional prices.The multicoating seems to be as good as many a more expensive filters, and the glass quality is very good, German optical glass.There is often some debate on whether to use protective filters on lenses, but I reckon they are good insurance from accidental damage or splashes, and easily removed if not wanted while shooting...like an optically clear lens cap.Happy to recommend these K&F filters, I've got several...

Fantstic does exactly what you need it for - cutting down glare and dust/object protection for the expensive lens behind it. Fits very well and has a quality feel that belies its price. Packaging is curiously luxurious on a product I doubt you will ever need to remove unless you are into multiple filters. Very impressed

I've used a few K&F filters on my camera lenses and have never been disappointed with their quality or price. Made from quality optical glass, the UV filter leaves no colour cast or other imperfections on my images; put simply, what you shoot is what you get, just nice, clean images. This type of filter also serves a second purpose as a protection filter for your expensive lens. After all, it's cheaper to replace a filter than a lens, isn't it?Overall I'm very happy with my K&F Concept 46MM UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter and have no hesitation in recommending it to others

My eyes have not yet noticed any undesirable changes. Unfortunately not extensively experienced to value if the results are better or neutral at least, which I think is the case and that works for me as this purchase, along with a few other similar ones (trying some of the other brands in this range also) is all about getting to know and evaluate (over time), what it’s like to be using filters, as well as adding the protection to my lenses, which if was the case alone, would be happy however. Negative effects was what I was hoping to not have and from what I can see myself and by reading a few other comments from more advanced users, it seems I’ve gotten what I was looking for. Nevertheless, there’s no doubt that there is a lot to understand regarding filters.

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 session. Being in the wilderness and in a country with strong sun rays I thought buying a new UV filter to protect my lens is the best thing. Now this is K&F product, same as my ND filter and the tripod I recently purchased because I am like that and like to buy loads from one company. It came really nicely packed and feels like really good quality and it fits perfectly. I am really happy with the product and look forward to using it and abusing it.

The important thing with filters is that they don't degrade image quality, and also that they have no colour cast or flaring on final images.As a pro photographer these are more important for me than most, and luckily these work perfectly.
