JONGSUN 95mm UV Filter, S-Pro HD Nano MRC Camera Ultraviolet Protection Filter, Multicoated, B270, Ultra-Slim, Lens Cloth Kit

UPDATE 12/21/2019:Please see review updates below leading to this latest update and a change for my review for this filter to 5 stars:First to say Jongsun did an awesome job for supporting a customer with issue on their lens. They stayed in touch with me all the way from China and got a replacement filter to me to test out and review accordingly. Julia there even apologized for the gap of delay due to time zone differences, although that courtesy wasn't needed.After testing over a week with and without this filter using controlled conditions, on a tripod, shutter speeds at least 1/1000 sec or faster. Focus verification on the exact same spot for with and without filter comparison, the images were unedited and un-sharpened RAW images and all looked identical filter on or off, at 600mm. The replacement, although the packaging and filter itself were identical to my precious filter that had the issues, "clearly", (no pun intended) did NOT degrade my Sigma at 600mm, the worst case for the issues I had with soft images and lack of sharpness/detail prior to the replacement.Haze filters that are ruining the Sigma 150-600mm (as well as the Tamron equivalent and the Nikon 200-500mm as well)are out there in forums......it is not chronic, but, then again, not everyone has a super-telephoto and thus, might never see an issue with a lower focal length telephoto.So in summary, the replacement that Jongsun sent me and in only a few days, resolved my issues.The filter is thin profile as many have said, but, no issues on my Sigma. The threads are fine and "dry".....so be gentle threading these on. I typically place the filter on the lens and gently turn it first counter-clockwise until I feel the slight "click" where the correct entry point on the thread alignment are for lens and filter and then begin screwing it in clockwise. this system has always worked well for me; no jams or cross-threading.So in summary, a great filter and a great company who stands behind their product and is willing to bend over backwards to try to resolve issues for their customer. I will be ordering a few more of their lenses for some upcoming new glass some time next year. JONGSUN has earned my continued business. Well done!UPDATE: 12/13/2019. JONGSUN contacted me and graciously provided another replacement for me to test my Sigma 150-600mm Contemporary lens with. That test is in progress and I will update this review accordingly w/i a few weeks . (by end of 12/2019).Given the excellent customer support and effort to try to resolve my issue with a replacement which they have provided, I will state, ...even though my tests are not completed, that they do support their customers 100% and fully stand behind their products.------------------------------------Having had a bad experience where all lens sharpness was totally destroyed using a cheaper 95mm haze with my Sigma 150-600mm, I had hopes this more expensive lens with multi-coating and higher quality glass would do the trick.It did not!Focus was perfect with and then without the filter and like my previous filter, as soon as this JONGSON filter was removed, my lens was back to stellar performance at 600mm.Will try to review forums on line and see who purchased a filter that actually will work fine with my Sigma.The degradation using this filter (like the previous one) is at 500-600mm. Given higher magnification probably maximizes the optical issues using the filter.I think one reviewer got a swap that seemed to work better, but, if this is indeed a quality control issue, (you either get a "good one" or a "bad one"), that scenario would still have me looking for another brand, hopefully a well known and trusted one!Returned it and my search will continue!

Admittedly I was a bit skeptical of the quality of these filters even as I ordered some of them. I've been using B+W filters for many years and I trust the quality of them. But I had several low priced Chinese made lenses that I had started to use (and really liked) so I decided to give Jongsun a try. It seemed strange to buy an expensive filter to use on a cheap lens and I felt a little adventurous anyway.The Jongsun filters are nicely made, fit perfectly and look great on the lens. I could detect no image deterioration when using them. They didn't bind going on or fail to stay on once in place. My gear gets used gently so I'm not expecting any problems to pop up in the future with the build.I may not abandon B+W but I see no reason to buy an expensive filter to protect a low priced lens unless the low priced filter is inferior. These are not inferior in any way that matters to me. Give 'em a try.

These filters look to be well-made, and feel solid despite their light weight. The packaging was superior and included a cleaning cloth--looks like they have the same package for most of their sizes-- 49 to 82+mm. The filters were purchased to protect the objective lenses of a very expensive binocular, which are built to accept 49mm filters. You can see the dust and particulates on the filters that would otherwise be on the lenses themselves. I expect they will provide some impact protection as well.Additionally, the claimed light transmission exceeds the claimed light transmission of the binocular, making any transmission loss negligible compared to the binocular. I say claimed because the average consumer isn't equipped to measure light loss thru a lensing system, so trust but with a bit of skepticism, right?Since I didn't put them on a camera lens, I can't say how they affect an image, but I do not notice any difference when using the binocular, which is how it should be.I don't think one can go wrong for the price with these filters.

The filter itself looks decent, but the case & box looks dirty!

Quality of the filter appears very good. But a 95mm filter doesn't need a case 6 1/2 inches square. It's nice to have a case in the camera bag and the monster case this filter comes in, is not manageable for the average camera bag. I'd give it 5 stars if the case were a normal size, but I had to design and 3D print one myself.

For my lense

I saw some negative reviews, but the same for all of the lower priced UV filters on Amazon. I needed a 95mm for a new Tamron 150-600 and decided to give this one a shot. It is very good. Zero noticeable impact on image quality on Nikon D800 36mp camera. No thread issues. No distortion or color interference. Seems to do a mundane task well.

attached very effectively to threading of my tampon 150-600 lens. Have taken only a modest number of pictures with the telephoto since getting the protection filter, but have noticed no loss of resolution and quality since started using it.

I was a bit uncertain about this brand as I have no experience of it having always used Hoya or Gobe filters in the past. I need not have worried. This filter is exceptionally well made. It looks a million dollars, is beautifully packaged and more to the point it does it's job without any visible effect on image quality. I will have no problem in using this brand again.

Bought two of these to protect my Sigma 105mm F1.4 and Sigma 150-600 Sport, when you spend the best part of £3000 on two lenses you dont want to damage the image quality by fitted a poor filter. Have to say Im incredibly impressed, the 105 is a phenomenally sharp pro lens and this does not degrade the image in the slightest, I do a lot of coastal photography so this regularly getsa splash of saltwater and cleans quickly and easily leaving no marks. A+++

I have been looking for a UV filter for a while now but some of the prices were a bit off-putting for a 105mm filter, then when I was looking on Amazon's site I noticed this one and the price seemed very reasonable, so I checked the reviews and again I was impressed by what some of them were saying so I placed an order and when it came I must say I was pleased with this purchase, It is a good fit (no sticking) and well made, I have not hade the chance to try it out yet so cannot say what it's like.

It seems to work very well, certainly in bright sunshine it does a fantastic job, clouds and sky look amazing, I use my camera for shooting military jets. The only one I haven't worked out yet is when the light drops the pictures seem to pixilate more, but this might be down to my Sigma Lens rather than the filter, but all in all I highly recommend this x

Well made, threads are well machined. As far as I can tell the filter does not seem to give any colour cast. The frame is also quite thin so it does not cause any darkening of the corners. Overall good value when compared to others.
