YSDIGI Ultra-Slim 43mm UV Filter Lens Filter UV Protection with Multi-Coated Ultraviolet UV Haze, High Definition Schott B270 Glass, Nano Coatings, for Outdoor Photography.

Using these on my Nikon 16-35mm f4 and 24-120mm f4.Absolutely no distortion and the glare/reflection reduction is excellent. In doing a reflectivity test with the face of the filter and the bright clear sky reflected into my eyes, the reduction in reflection is quite evident!The coating by the way does not alter color rendition at all, though if you look at the slight coloration of the anti-reflective coating you might think so. With and without color charts tests showed no impact at all on color accuracy (nor exposure).Being these have a very thin/slim profile, they may screw on with a bit more "fussy-ness" than a full thickness one.My trick is to place the filter perfectly parallel to the lens and on to the threaded area and set it gently, ready to mesh with the threads, then rotate very slowly as if removing the filter until you feel the threads of filter and lens subtly "click" and align, then begin screwing it on. This technique has worked well for me for all lenses I use with slim profile filters and I've never cross-threaded any filter doing it this way.Anyway, very nice filter and build quality, comes in a very nice protective "pillbox" hinged protective case and I plan to buy this brand again for my polarizers and NDs.5 star for sure!

I typically buy the 'big name' filters but I needed a 'price sensitive' 37mm filter for my new small M4/3 lens. I am blown away at the quality of the build... the attention to detail (the front of the ring has a knurled angled area to assist in removal etc), and the thinness of the filter. All in all... it is a VERY worthwhile serious look when you are in the market for filters. Who knew?Anyway... I don't do a lot of reviews... too time consuming for the amount of items I purchase... but this one was worth mentioning so to possibly help others to know they can feel safe with the brand.Highly recommended!

The manufacturer makes big claims for this low-priced filter. I figured it was worth a try, since I'm used to B+W filters. The packaging was excellent, protecting the filter in an oversized package (I guess made for big sizes). I put it on a kit lens and took it out. I took some shots with and without the filter. Even some shots with the sun in the shot. I have to say that it was very hard to tell the difference between the filter and no filter in terms of distortion, reflections, and flare. I didn't do a scientific test, but was satisfied that the filter would do the job and it was very attractively priced.

Excellent value. Excellent product. I will be purchasing another for a different lens next. I would recommend this UV filter because it is a TRUE UV filter, with multiple coatings vs. a simple piece of clear glass that is more of a protective barrier for your precious lens. In truth, a protective lens on the front of your high end glass is really unnecessary, your lens glass is incredibly tough. I won't go into detail here, but you can Google information on how to tell the difference between simple protective filters that claim to be UV filters vs. REAL UV filters and can learn why a UV filter makes a difference. Many lenses these days, however, are multicoated already, so no protective filter is necessary. I use many vintage lenses on my cameras and I do actually use UV filters. Yes, I would recommend this multicoated UV lens filter.

I own several of these filters now and what you get for the price is unbelievable. These are great quality filters but the packaging these come with was unexpected. While I'll never use the packaging again and the case is far bigger/bulkier than it needs to be, the fact it comes with decent packaging and a case? I don't see how they make money off them. The filter is clear and optically brilliant for the price. The frame is slim and the threads have been flawless, quality build all the way around. They could easily charge twice as much and I would still find them a bargain at that price.

Its a UV filter - it should be optically invisible; real purpose is to protect lens itself from damage. So far so good.No flares/ghosts in the few test pics I've taken.Compared to the Amazon basic filter, it is *much* slimmer - like 1/2 as thick.Only downside is the slimmer design has fewer available threads and cross-threads easily, which would be an issue if you were taking it on/off frequently. I leave these in place for protection & my CPL threads ONTO it without issue.

I am a professional photographer and have some fairly expensive glass. I usually buy expensive known brand filters. Not sure why I bought this but used it on a shoot today and was amazed at how well it did. Looking at the images full size on my computer no degradation of IQ at all. So far I’m impressed- excellent value.Ps. You don’t need a UV filter on a digital camera. They are only for film cameras but not many people make good skylights.

The filter came in a very nice package. The filter container--round in shape, feels very solid, and much better than those from many other filter brands, such as HOYA. There is also a microfiber cloth included in the package. Nice!The filter works very well, and the coating is comparable to my Hoya HMC UV filter, in terms of light reflection.
