Bought for a Sigma Art Sony 24-70 and the Sony 28-135 (with Step Down), it is now permanently on my lenses. Additionally, having an ND and a polarizer on the same filter is a really nice surprise, especially at this diameter. For video recording and holding at 1/50 or 1/100 in broad daylight, this is best. A highly recommended essential.

Really pleased with the quality of the filter and happy to report that there is no X cross issue and or colour cast.

This polarizing filter and neutral density filter pleasantly surprised me, it does not have an excessive price and the quality of the photos is not bad, I took several photos with varying degrees of which allows the light to be subtracted and the result is good, if you like silk effects in water this is a must-have filter. It also has the polarizer which eliminates reflections on crystalline surfaces

I wasn't entirely sure about the price at first, but that quickly changed when I started using them. I had tried the K&F in the next higher price range, but found that I couldn't justify it for my pure amateur photography. If you want good quality at a reasonable price, these are worth a look. If you are more professional / business minded you don't need reviews made by amateurs like me on Amazon. All in all, I can warmly recommend these filters - I'm lucky enough to only need three thread sizes for my Canon L-series lenses, otherwise it could get very expensive!

It is a variable and polarizing ND filter. The ND is 5 steps, there are double, 10 steps (ND1000, 1024 to be exact). The polarizing filter eliminates light reflections on surfaces, cars, water, glass, also enhances the colors of the sky, leaves, asphalt, etc... (for more information search the Internet ) I personally use it for video, so as not to lose aperture-closing depth of field (f9 forward, now I can go to f2.3 without burning the frames due to excess light). I haven't removed it from my 35mm in a while, I'm delighted. The filter is made of metal and glass, presented in a rigid plastic case for storage. You can see the protective and anti-glare layers of a greenish color and you can put the dingle on it which holds quite well without staining. The lever changes the density of the filter and the other ring moves the polarizing filter. You have to be careful with this because you can move both carelessly. In the pictures you see the filter attached to an adapter, (step-up 49mm to 67mm) this is because I have 67 and 49 filters, my advice is to buy large filters then "step-up" adapters ". On image quality. Well, excellent: there are no casts, no chromatic aberration, no loss of definition or the terrible X of the ND gradual filters appear. I have a very expensive polarizing filter and barely notice the difference on it. As a negative point although I have already said it,

Dear kF, I want to thank you for your follow up message regarding my satisfaction on my order. You really care about customer service and really appreciate that...the ND 67mm is amazing and I'm very happy with it. I know this is about reviewing the product, but I'm so grateful that I went above and beyond for your customer and it's priceless. I recommend this product and the shopping experience. Thanks for doing it right.

For the price this is fantastic. I'm only a student so the like of polar pro and such are out of reach and was always stuck with cheap brands (including older K&F's) that ruined image quality with x marks and colour cast.
But then I discovered this and I have to say I'm impressed. No colour casting or 'X' patterns and my footage looks crisp as if there was no filter at all. And the fact that it's a CPL aswell is a huge plus.

Would recommend.

We bought this 2-in-1 filter for a shoot that was shot outdoors. We encountered no problems filming at the water's edge with the glare of the sun. For the price it's excellent, the variable ND2 to ND32 filter is really sufficient for video. It is possible thanks to the filter to keep cinema look parameters on the camera, with a large aperture, a low iso and a nice bokeh. The filter is of good quality to the touch, we realize that it will not break after several screwing and unscrewing. The advantage of this filter also lies in the 2 small peaks, which make it possible to properly adjust the ND part of the filter. In short, if you want to buy a filter for your camera, we recommend it given its price. Really great!

(search the internet for more information) Personally, I use it for videos so as not to by closing the shutter to lose depth of field (f9 up, now I can go to f2.3 without burning the frames due to too much light). I haven't removed it from my 35mm in a long time, I'm thrilled.
