Great versatile magnetic system that holds
For an upcoming trip to Iceland, I was looking for a magnetic polarizing filter and an ND filter. That's how I came across the K&F. I already own several items from this manufacturer (CPL filters, clamps) and have been satisfied so far.
I ordered and tested it. Quick mounting thanks to the magnetic system, the variable ND system works reliably, and the lens cap fits securely and firmly. I used it for filming with a 50mm f/1.2 and a wide-angle lens. Due to its design, it's so thin that there's no vignetting at 14mm on an FX camera.
Adjusting it is smooth and without any jerking. I haven't noticed any significant color shift so far. The included case is robust and protects the filters during transport. A benefit of the magnetic system is that I can leave the ring permanently mounted and quickly attach the CPL filter or the ND filter.
I highly recommend it.
The third image shows the sky at 14mm out of camera.
