Muy buena calidad y muy buen estuche

Little expensive but gets the job done. Beautiful pictures and good clarity maintained. Using this with a step up filter with my sigma 18-50 2.8. Happy with the performance, recommended !!

The K&F Concept 95mm Variable ND CPL Filter is an absolute game-changer for my photography! The 2-in-1 design, combining a variable ND filter and a circular polarizer, offers incredible versatility and saves me the hassle of switching between filters. The ND2-32 range is perfect for controlling light in various conditions, and the polarizer effectively reduces glare and enhances colors for stunning, true-to-life images.The build quality is excellent, with smooth adjustment rings that feel solid and easy to use. The filter doesn’t affect image quality, maintaining sharpness and clarity even in challenging lighting conditions. It’s a must-have for long exposure shots, landscape photography, or any situation requiring precise light control.If you’re looking for a reliable, high-quality filter that combines functionality and convenience, the K&F Concept Variable ND CPL Filter is a fantastic choice. Highly recommend it for photographers at any level!

Great quality of coating. Doesn’t ruin pictures neither on min nor max position.Has two cons:No cap can be attached.ND ring easy shifts CPL, gotta hold CPL when adjusting ND.In general - great filter.Picture of the solar eclipse taken with this exact filter.

This USB flash drive case is super handy! It fits all my thumb drives, SD cards, and even some extra cables in the mesh pocket. The foam slots hold everything snug but are easy to use. Plus, the waterproof PU leather and sturdy zipper give major peace of mind. It’s compact, lightweight, and perfect for travel or just staying organized. Honestly, it’s a lifesaver for anyone with a ton of tech accessories!

The product might seem a bit over priced but for the quality and functionality it offers, it's a worth buy. There's no X mark in images shot with this and that's a huge plus point.

Good product for the beginners and professionals in affordable price . But in wide angle lens you will get the vignettes around the corner . Can avoid this by zooming very little.

Cpl working good but when you change nd site than cpl filter change

Bought this for my 35mm f2 which I am using on a Canon RP. I wanted it for slowing down the shutter speed for waterfalls I'll visit this summer, as well as deepening the blue in skies. It works as advertised. Nice metal build quality that feels well made. I like the stiffness on the variable ND part. It stays where I set it, and so far it's working great at reducing the light coming into the camera, allowing me to use longer shutter speeds to get the flowing water effect I was after. I usually use the polarizing part of the filter on the lowest ND setting. I'm adding two photos that I think show the polarizing effect pretty clearly. There is some colour difference between using the filter vs not as well as at different filter settings (rotations). I think this is pretty standard, at least I've observed it in the polarizing filters I've used in the past. I've been satisfied dealing with colour shifting using WB and calibration adjustments on raw files in Lightroom. I don't see any degradation in sharpness. I'm pretty picky and do view files at 100%. Very glad I purchased this filter combo. Great value for the money! I'll also add that I accidentally used it once over a thin UV filter and was glad to not see any vignetting.

I've had this filter for a while now and it works very well however, I would not get a CPL/ND filter combination again. I think these two things should be separate. Also, I use it with a Smallrig Matte Box (2660) with the reduction ring made for it and once installed, I saw that the adjustment handles get stuck on the top and bottom of the matte box; it's just too tight in there! The work around is to turn the CPL part a bit and then you can do the adjustments but then, to change your CPL filter, you have to use both hands inside the matte box which are in the way from seeing anything so unfortunately, not the best combination. Otherwise, if you plan on using it without a matte box, this filter works really great.

To make it short - this combo filter is very good value for money, as long as you're getting it for the right reasons. While not quite up there with "pro-level" filters in terms of quality, it does a great job for what it is.Firstly, the main appeal of this filter is combining CPL and variable ND functions onto one - which saves you from having to stack multiple filters (which may end up not working well together) and makes for one less piece of glass between your lens and your target. I've noticed no flaws whatsoever in how the two functions work together - no Xs, no artifacts. The CPL part of the filter is very, very good. The variable ND part is... fine. Better than a lot of filters in this price range. There is still a slight brownish cast from it, but it's totally consistent and very easy to correct in post-processing. Just don't expect stellar results right out of the camera, without a couple of clicks' worth of extra work!In terms of filter factor, it's more or less spot on - it's a little bit more than 1 stop of light at the lowest setting (ND2), but at the highest setting it seems to be pretty much exactly 5 stops of light - not the 5 and a half you'd get if you took an ND32 filter and put a CPL over it.However, the real question is: do you need this filter? Because the max setting of ND32 is generally a bit too light for landscape photography off a tripod (you'll want an ND64 or even ND100 filter there). For longer telephoto lenses (over 200mm focal length), you really don't need this kind of filter for the obvious reason that you're not likely to be getting too much light. For wide-angle lenses, the CPL portion makes it a complete no-go - on anything shorter than 35mm focal length, it'll completely mess up your image with those uneven shadows (not the filter's fault - but CPL is really not designed for that).So, what is this for, exactly?Well, I can't speak for video usage - but in stills photography there's one area where this filter really excels, and that is for handheld shooting in bright daylight conditions with large, wide-aperture lenses at the higher end of portrait and lower end of telephoto: in other words, lenses between 80mm and 200mm focal length and f/2.8 or less when wide open. This allows you to really control and thin out your depth of field and shoot at shutter speed that will minimize noise, while being able to control more of the stray light from reflections thanks to the CPL.I use it for creative photography with just two such lenses, both totally manual: the Samyang 135mm f/2, and the Helios 40-2 (85mm f/1.5). It is very handy with both, really hits a sweet spot for usability despite how bulky those lenses themselves are, and really brings out the kind of extreme subject isolation and bokeh both of them are capable of. So, if you own monster prime lenses of that kind (between 80 and 200mm, f/2.8 or less) - this is a great filter you really will find useful. But beyond those? Might be worth checking something else!Otherwise, my only other criticisms are about ergonomics: the filter uses some kind of non-standard thread on the outside, and has too little thread left anyway to screw anything over it - so if you were thinking of putting a hood or any other sort of attachment over it, you'll have to forget it. And on too of that, the little "handles" for controlling the ND variation stick out just a bit too far from the body of the filter... so you can't really attach a lens hood behind it either, save for a flexible rubber one - and even then, the "handles" will likely deform it a bit. Long story short - expect this filter to always end up on the very end of your optical train, and expect to have trouble even fitting a lens cap over it without it constantly falling off. It's not a big deal as far as I'm concerned - but you may find yourself putting this filter on and taking it off to store it in a box every time you go out to shoot. Not ideal if you want to put it on a lens and forget about it.All in all though, I'm very happy with it! Worthy buy and a handy tool to use.
