K&F Concept 52mm Variable Fader ND2-ND32 ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens No X Spot Weather Sealed

Low quality filter with lot of air gap and fungus formed because of that

I would love to try this out because lots of YouTubers said that this is nice. Well I guess I put too high of expectations. It’s good and affordable so it makes sense but I thought it’s gonna be better quality. It’s a bit wiggly for me. I cannot change only one of the polarizer or the nd filter. Whenever I turn the nd filter, the polarizer also turns, so it’s a little bit difficult to adjust only 1 of the filters.

I seriously don’t have an idea what’s going on with K&P , To say that this filter don’t have X , when it have!But only on wide lenses..I use this on my 18mm samyang / rokinonAnd it’s clear as the air around me that this filter have X mark when you pass the maximum ND ..I tried with a 35mm lens, and there is no X .So I guess that with wide lenses, it’s not working.But why they didn’t mention it??Now regards the CPLI didn’t see any effects from is, like it’s not working….So I suggest to K&P to be more honest

This filter is excellent if you want the convenience of a dual filter (CPL and ND) and a continuously variable ND filter. It functioned flawlessly. Be aware though that it's a little more difficult to adjust because of the physical structure of the lens but that's not an issue with the design or this company. It's just the nature of combination filters like this. Also be aware that this filter is of course, twice as heavy as a separate filters used individually. This means it can be a bit more difficult to balance on a lens on a smartphone if you use a gimbal. I still was able to though using offset weights on my gimbal.

52mm ND2-ND32 (1-5 Stop) Variable ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens. What can I say about it? Exceptional. Having the ability to simultaneously adjust the ND filter and polarization without swapping out filters is super convenient. Quick adjustments can make a big difference in whether you get that perfect shot or video pan in the moment. I have a Sony ZV-1 with a 52mm adapter for lens and it seamlessly and smoothly threads on without issue. Although my camera come with a build in ND filter. The K&F takes it even further by along more control of how much light my camera takes in. The polarization aspect of the K&F further expanses on the quality of the picture. Overall, I’m extremely happy with this product.

This is one serious filter. Most filters I’ve used seem very cheaply made but this thing looks like a serious piece of hardware.I was blown away by how smooth the knob is and how you can actually adjust the filter from light to dark. This will come in very handy for long exposures, especially during the day. You can’t have a long exposure with too much light, but this solves that problem.The filter doesn’t alter the image at all or cause any kind of weird side effects. It’s crystal clear and just as sharp as if it’s wasn’t there.I also love that you get a padded carrying case to keep your new filter safe and the included cleaning cloth is a nice touch.
