A highly recommended filter set at an affordable price.
I opted for the 77mm set because it fits four of my Canon lenses. I tested it with the RF 100-500mm F4.5-7.1 L IS USM. The CPL filter performs exceptionally well, the ND filter is precise, and I couldn't detect any optical distortion. I haven't yet had a suitable opportunity to test the Black Diffusion filter.
What I would like to see is a second mounting ring, as this would make switching between lenses much easier. Since the magnetic filters adhere strongly, a kind of "grip" similar to the knurled screw on the CPL filter would be helpful for easier removal. This would also be very useful for avoiding touching the filter surface with your fingers when taking the filters out of the case.
