Water drops roll off as expected from a true nano coating. Mechanically sound, good for lens protection.

L'ho preso perché molto sottile, come protezione per la lente frontale, sperando che fosse di buona qualità, e non mi ha deluso. Prezzo accettabile.

un bel filtro non e il primo che compro ma a il vantaggio di essere veramente slim ed un aria molto da prof.

Considerato il prezzo è molto ben fatto e non modifica l’immagine. Certo in studio lo tolgo ma se sono in giro per fare qualche scatto è ben saldo a proteggere la lente

Correspond tout à fait à mes attentes. Fonctionne parfaitement. Je recommande !

Immediatamente adoperato su zoom Sony migliora il contrasto e i colori dell’immagine grazie al filtraggio degli ultravioletti parassiti. Ottimo Prodotto

Der Filter macht was er soll, beeinträchtigt nicht die Bildqualität oder ähnliches, das gewinde ist sehr fein gearbeitet und läßt sich schön leicht aufschrauben alles sitzt sehr präzise. Für den Preis ein top Produkt. Kann ich ohne weiteres empfehlen.

il trattamento multistrato è veramente efficace, anche la costruzione è ben fatta

Acquistato per proteggere la mia Fujifilm X-100V.Ero già in possesso l’adattatore opzionale AR-X100 e mi mancava il filtro di protezione (Fuji propone il PRF-49) per cui ho acquistato questo prodotto che dalle caratteristiche dichiarate sembra valido.

IntroduzioneIn questa fascia di prezzo non aspettatevi filtri di grande qualità, sono onesti e offrono un buon rapporto qualità prezzo per un uso amatoriale.ConfezioneIl filtro arriva in un ottima confezione rigida in plastica con un panno in microfibra di buona qualità.CostruzioneIl filtro presenta una montatura in alluminio dalla filettatura precisa e solida, lo avrei preferito senza l'anello dorato sul bordo.QualitàLa qualità è buona, nel mio caso viene utilizzato su di una Fujifilm X100V come protezione dalle intemperie. Il degrado nella qualità di immagine c'è, ma si presenta in condizioni di illuminazione difficili come fonti luminose molto forti e dirette, situazioni ad alto contrasto e tante fonti di luce nella stessa scena. Questo porta a flare e riflessi verde chiaro ed una leggera perdita di contrasto e nitidezza. Utilizzo professionalmente la X100V per lavori di reportage e in caso di situazioni tranquille smonto il filtro per avere la massima qualità. In caso di pioggia, intemperie e rischi per l'obiettivo, trovo accettabile la perdita di qualità.ConclusionePer il prezzo a cui è proposto ed un utilizzo amatoriale mi sento di consigliarlo. Per chi ha un budget più alto o professionisti che vogliono tenerlo montato H24 io andrei su B+W, Manfrotto o Hoya. Per avere una qualità superiore bisogna spendere dai 35 ai 70 euro.

I have purchased and now have experience with 4 of these in different sizes. I am a very fussy photographer and these filters work as described.While I can't verify that these are Schott glass, the glass is indeed planar and exhibits evidence of good coatings when viewed at an angle. Looking straight through them the image is perfectly clear with neglible reflections which is important for a DSLR.Photos taken with them on compared to them off reveal no image distortion even with pixel peeping and no change in exposure settings so the claim of 99+% transmission is probably correct.Recommended.

Filtro sottile e ottimamente realizzato. Non si vede quasi quando è montato.al primo approccio mi pare ottimo,come altri che già ho della stessa marca. Prodotto di alta qualità, consigliato.

UPDATE 8/4/24. Well, my fault, left the filter on for over 2 years and tried to remove it 8/1/24.....it would not come off even though I tried every technique out there. It was stuck hard as if superglued on! I ended up, pointing lens down and gently breaking the glass and removing it using a soft plastic implement, wrapping protective tape around edge of lens outside of filter and very carefully used pliers to twist the filter ring off until it dropped out. Have to say, that ring is well made. Even the leverage I had with pliers was challenged by the excellent strength of that filter ring!I purchase a replacement and tested it on my new Nikon Z 180-600mm. No issues with focus at all. Images look identical with or without the filter. Focus accuracy and response was not impacted at all with this filter!I will now screw my 95mm haze filter on ever so gently and remove it for storage of the lens.I also applied a q-tip of iKlear Apple screen polish (Amazon sells it) to the filter threads and base at bottom of filter threads/filter body and than gently wiped it off using a clean micro-cloth. This might offer a bit of help to reduce friction in the filter thread area to avoid a stuck filter in the future.Still 5 stars and this replacement is a keeper!-------------------------------------------------------------------------------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!
