40.5mm MCUV Filter ultra-thin Trapezoid Patterned Frame Coating with a Vacuum Cleaning Cloth Nano-Klear
SKU: KF01.K40V2
have a few Sigma Art lenses that require a large 82mm filter, so I wanted something that I could only use in a harsh environment to protect these expensive lenses. Something of good optical quality but not very expensive to replace if necessary and these conditions will probably make it necessary. I was so impressed with initial test shots I took under various lighting conditions that I won't hesitate to use this filter if the conditions require it. I attribute the optical quality to the 18 layers of multi-coating. This isn't my first filter from K&F Concept, so I wasn't surprised at all. However, I am surprised at the retail price for a filter of this quality. While the widest lens I'll use with this filter is 40mm, the thin frame should allow it to be used at much shorter focal lengths without vignetting. Taking into account the current retail price, five stars for excellent quality and value for money from a trusted brand.

That's 100% the reason to buy one of these. Think of it like a screen protector for your phone. scratched? throw it away, buy a new one. Dirty or watermarked by the rain? wipe it off The point is that your expensive glass stays safe underneath.

Fantstic does exactly what you need it to do — reducing glare and dust and object protection for the expensive lens behind it. Fits very well and feels quality which suggests about the price. The packaging of a product I doubt you'll ever need to remove is oddly luxurious, unless you use multiple filters. Very impressive

The glass in this filter is very thin. I haven't had a chance to test whether it holds up to being banged around or not. I wouldn't use this filter in my bag without a lens cap, but I know it will protect against minor abrasions, dirt, and scratches. I like the knurled edge that helps me grip it and remove it from my camera with the deeply built-in lens hood. So far no noticeable deterioration in the quality of additional refractions!

have bought several of these UV filters in various sizes over the past few years. I've never had a single complaint to the effect that they are crystal clear and do the job they are made for. Milled, slightly raised edges on the metal ring, making it easy to assemble. All in all a great product at a great price. Why pay more?

This is a very nice high quality protective filter, it is lightweight, has nice little handles on the edges and appears to be well made with good quality control. Unlike some other filters I have purchased that have had blemishes or imperfections in the glass, this one has no such defects. It was well packaged, perfectly clean and easily clipped onto my lens. As a bonus, a small but very useful microfiber cleaning cloth was included which looks better than some others that were provided FREE with other purchases. This cloth works great. I actually used it on my glasses and it didn't leave any stains. Overall I think this is a good choice, if you are looking for a simple but well made filter that will mainly protect your lens from dirt and damage then this is a must have.

I needed an ultra-thin UV filter for my wide angle lens and this filter works great! I was still able to screw in the lens hood and not get any vignette in the corners. This filter also seems to alleviate some of the glare I experienced. The surface of the filter is super clear and doesn't interfere with my camera's autofocus. We recommend.
