K&F Concept K&F Concept 67mm Variable Fader ND2-ND32 ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens No X Spot Weather Sealed

Nice product

I'm using this for a month now and its quality is awesome. I never felt to take the filter out to capture best shot, its always there on the lens. Protect the lens + add ND and CPL as an when required immediately. Only one drawback i found is while traveling on flight and taking photos and videos i got rainbow so i removed the filter on flight video and put it on again while on the ground.

Good but not excellent

Impressive quality

Good product

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 !!

Not value for money. The adjustments would never go as you would expect it to go. Material Quality is ok. But what's the use, when it cannot perform the task for which you would buy for.

Since I started doing long exposures , my variable ND filter of choice was Vivitar. It's worked great over the years but I was in need of a new filter. Since I also own a K&F Concept tripod, and they've treated me well, I decided to give this filter a try. What could be cooler than an ND filter and a circular polarizer in one?! And I'm glad that I did! This filter works incredibly well. With my old ND filter, I had to stack a separate circular polarizer on top which would lead to vignetting on my widest shots. With the K&F Concept 2-in-1 filter, that no longer appears to be a concern at 18mm. At 10mm, I've noticed a very slight vignetting which is almost unnoticeable. But, it's definitely a huge improvement over filter stacking. While it may require 2 hands, this filter is very easy to adjust. It also feels well built and sturdy. All in all, this filter was well worth the money invested.

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.

It’s good for the price, but does cause unwanted vignetting at some distances and it’s super annoying that the filter thread is larger than the lens thread - so you can’t keep it on your lens unless you buy a larger lens cap. But it’s convenient and can produce some great quality images.

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.
