K&F CONCEPT 52mm Polarising Filter CPL Filter Multi-Coated Japan Optics | No Vignetting, Reduce Glare, Sky Water Landscape Photography Camera Lens Filter with Cleaning Cloth Nano-K Series FC301

I bought a set of these in different sizes to suit three lenses. Fair value for simple lens protection and image adjustment. Easy to fit and adjust.

Good value for money lens protection. There are more expensive CPL out there but for the price this is ok.

A very durable filter that removes reflections and reduces the brightness by 1 to 2 stops, useful for photographing the moon. It cleans easily with a microfiber cloth. Good filter for a good price with good thread options.

This was bought for my Panasonic DC-FZ82D camera. It fits nicely and works well insofar as it reduces reflections. However, it also significantly reduces the transmission of light through the lens. This is a problem when trying to photograph pictures and items in galleries and museums which are behind reflective glass; there is little enough light in those situations. It's a long time since I last used a polarising filter and I don't recall the loss of light being so great in the past. Maybe a more expensive filter would allow more light through while still effectively blocking reflections?

Another excellent K&F product.

I've used quite a few K&F Concept products before, and always found them to be decent quality. The polarisation does a good job of eliminating unwanted reflections and bringing out cloud detail in the sky.

I both two of these and have mixed results: - A 40.5mm filter for a 28-60mm zoom lens and it was good. Perfectly sharp, good filtering. It has quite a warm colour cast, but for the price, this was acceptible. - A 67mm filter for a 70-180mm zoom lens, which was unfortunately terrible. Even at 70mm, the image quality had this directional blur to it which only got worse as the focal length increased. I don't know if this was a fauly item, or just some combination of the long-ish focal length and larger diameter.

Ordered a cheapish filter to begin with to see if suited me. At first fit it appeared not to vary polarising effect as I rotated it on the camera. But upon further trials on the reflections off my car bonnet, it does vary with rotation as described. Just got to get the angle right. Quality is very good for a budget filter, but one thing I don't like is how hard it can be to remove from lens. Iy takes a few rotations on sliding ring before it seems to pick up on the threads and starts to unscrew. Not a massive issue, but would be a right pain if needing to remove in a hurry.

A pretty good CPL filter. I like the quality, but there is one downside - lens cap no longer fits :(

Disappointed. Not as described. It just mskes a shade on picture.

Like, the headline says, this IS technically the low-level when it comes to K&F filters... however, it performs wonderfully. For me, I had no issues using it and noticed no lack of detail or focusing ability. If there WAS any detail technically lost, it was more than made up for with the clarity of the image without glares. Obviously, the effect was most noticeable on windows, rivers, etc... but in certain circumstances try using this for portraits and you'll notice some of the specular highlights dissolve to create a more even result! This was something I accidentally discovered, but later found out is a fairly common use. I 100% would recommend having this as a new photographer or even maybe as an older photographer. If you're just a hobbyist photographer, this will help out and it will not break the bank. You won't notice any difference between this and a $400 CPL until you start getting technical with how you want to push your composition. At that point, you can look into higher "quality" glass, but in general, I see no problem with this filter for general use and always carry one in my filter case either as a backup or to use in dusty weather, rain, etc to keep from harming my nicer filters.

Need I say more?

Très bon rapport qualité prix
