Overall a pretty good quality CPL filter. The additional lens cap, lanyard, and cleaning cloth are a nice bonus, too. The filter rotates quite smoothly, and screws on to my lens well. The glass is pretty clear, and doesn't seem to cause too much softness, although there still is a bit compared to no filter. The reduction in glare and sky darkening effect is quite significant, and is great for taking pictures of more stationary things. I wouldn't recommend these too much if you're taking pictures of moving objects, though, as panning the camera will change your angle with respect to the sun, and therefore will change the strength of the polarizing effect.

Produit gratuit testé dans le cadre du programme du club des testeurs Vine, sans rémunération pour donner une note et un avis qui sont basés sur mon utilisation au quotidien et qui n'engagent que moi.Les produits K&F ont bonne réputation et je n'ai pas hésité à commander ce filtre polarisant circulaire pour utiliser sur mon Tamron 150-500 en 82 mm.Le filtre, visiblement de qualité, est livré bien calé par une mousse compacte dans un étui plastique, bouchon fixé dessus.J'apprécie :- la bague fine mais solide,- le filtre se visse/dévisse tout en douceur sur l'objectif,- le bon grip pour régler facilement le niveau de polarisant,- le bouchon d'objectif et la courroie compatible avec le pare soleil "au repos" le long du fût. Plus fin que le Tamron d'origine, il a d'ailleurs pris sa place !- l'étanchéité à l'eau qui glisse rapidement,- le chiffon.Je regrette :Rien pour le moment.A ce stade, je n'ai pas remarqué de variation de couleur ou luminosité, du moins rien qui ne puisse être réglé facilement au post traitement.Répond parfaitement à mon attente pour un filtre polarisant de qualité.

K&F has been a great company my husband and I always go to for camera accessories. We've used this brand for a similar filter in the 85mm size and now that we have a different lens, we opted for the 58mm polarizer filter. It is super thin as they say and it works really well. It helps with shutter motion and when taking portraits because it allows less light into the lens if you're looking for a moodier vibe and reduces reflections. Kind of acts like an ND filter and provides a little more contrast and color.

I Love it!

This arrived quickly in the mail after ordering. It came USPS and in a Amazon cushioned envelope. You can see all of its wrappings in pictures above. It came professionally wrapped with very professional Packaging. Everything from top to bottom is high quality the lens is a very good quality and the metal casing to the lens itself is extremely high quality I love the gnarled edges around it so that you can grip the filter itself to thread it onto the lens it cuts out the UV no matter which way you turn the lens so this particular product you don't have to have the lens turnt a certain way in order for it to work it works and 360° of rotation. It came with a lanyard and a microfiber cleaning cloth which was very good quality in itself tough durable and I tested it out it does clean very well it gets off all debris and grease with minimal effort. A lot of cloths just seem to smear grease around or hand oil around but this takes it off makes it look shiny and new with no residue. The lens cap is of great quality it's very thick the clamps are tough and rugged and don't seem to come off with any little bump they actually have to be squeezed pretty good in order for them to come off of the filter itself but it's not so difficult that you have to work at it to get it off functions as it should. This isn't my first product from K & F I've been using their products for years as you can see in the photos above I have some of their lens adapters and I've had their products for other cameras that I have mostly vintage. I've been impressed Through The Years with their products and this doesn't stop it with this one it impressed me I've went through a lot of brands of filters and I tell you they all have something with them that you know they're not perfect but this one seems to be perfect in every way it is more than just a lens cover it has a function that serves a purpose and I plan on leaving it planted on my lenses always. I will definitely go back and buy more for sure. It screwed on to my lens very easily I did do the typical turn it the opposite direction you're supposed to to get it to fit into the threads first and once you hear that initial click and you know it's seated properly then you turn it to the right to tighten it in and it goes right in beautifully the lens hoods that I had fit over it not that you will need it but it never hurts to have it affixed. The lanyard went on easily and it's tough it also has a cinch on it to cinch it up to your wrist as per the picture above that it doesn't slide or fall off or if you're taking a picture and someone runs past you and tries to grab your camera they will not get it easily from you you will be able to hold on to that camera tightly for you tourists out there. There's a time for a strap and there's a time for a lanyard and most of the time I find that the lanyard is more convenient than a strap the strap becomes cumbersome and most of the time you find that it's in the way it's not even that great for letting it just hang on your neck to where the lanyard it's their cameras in your hand all the time and it's there until you're ready to not have it in your hand anymore you don't have to worry about it if I want to just let it hang I can let it hang and it's just fine granted the bigger the camera the more of a pain the lanyard is but for everything that's a medium to small size camera lanyards or the way to go I believe you're getting a lot for your money with this product and this is a company that you can rely on for multiple photography applications both for photography itself and video this lens works great for taking video footage and keeping the glare off not just the glare off but keeping the ultraviolet down so that you're getting true to color and you can see once you've applied it to your camera how it's going to be and I guarantee you you're going to like it I did there's some pictures above of things that I took photos of in the yard immediately after installing it on my lens and you can tell there that it didn't affect the color of any of those items but it did take the glare off of those items and left them true to color very vibrant I didn't know doctoring to the photos those are raw photos and you could see that everything is very detailed. Are there more expensive filters for cameras? Yes there are more expensive filters but I have to say that these fit the bill for most any filter that you're going to every need or use and they are a fraction of the price you will get professional quality if you have professional equipment if you have generic equipment you're going to get the quality that that product is going to produce and not a miracle from a lens filter LOL.

Une référence pour moi dans le domaine des filtres, un très bon filtre polarisant.

Over the last few years I've ordered a number of filters, from several of the different K&F series filter lines, and with only a VERY few instances, I've been happy with all of them. This "K&F Concept 72mm Circular Polarizer Lens Filter [CPL]" is another plus product from them.I ordered this 72mm filter as an experiment to see how it would work matched with my Sigma 15mm f/1.28 EX DG fisheye lens. But because this lens incorporates a large bubble for the front element I wanted to try screwing it into the extended lens cap and the experiment was then whether the CPL would still work. Having screwed it into the extended cap the filter rotated smoothly. Photographically, however, although the CPL filter did a good job with both sky color and water reflections the barrel efect of the lens as increased by the extended cap's distance from the lens element made the pictures not worth reprinting here. Despite that result, I will be keeping, rather than returning, the lens for use with 72mm camera lenses that I will no doubt be buying in the future.All in all I think that this "K&F Concept 72mm Circular Polarizer Lens Filter" is a good buy given its mid-range cost and better than average performance. I think it is a solid 4 star product which should be considered by anyone in the market for such a CPL filter.(Please see below for my rating criteria):=============================================================Disclosure:As noted by Amazon, I am part of the Vine Program which means that I acquire products at no cost in return for a truthful rating.

This filter belongs to nano x series line which is more of their higher end but not the Nano X Pro line. This CPL filter works pretty good with no issues whatsoever. The quality build on this model it's much better in my opinion. I didn't notice any color shift whatsoever with this version. It does not affect any image quality whatsoever as well. Been using this version for a few months without any issues. I have included two images where I'm shining my UV light directly through the glass, notice how it blocks UV light. Probably not the best UV test but my higher end filters do the same with the UV light. I like their nano x serious along with the nano x Pro series.

Ich bin sehr zufrieden mit dem CPL-Filter er wurde mir auch pünktlich gesendet ! Mit freundlichen Grüßen W.Ehrhardt

Feels constructed well, lens cap a bonus although I'm still using oem one. Lens cloth always useful. Works as expected though I don't constantly use these for polarization; I imagine could be extra protection for kid events in case something goes flying, but that hasn't happened so far.
