I picked up a K&F concept for my Sony 11mm f/1.8 with polarizer combo. I like it.

Are there any issues with color cast, crosshatching X pattern, loss in sharpness or contrast?

Very little crosshatching at full ND setting and hitting the certain polarization, I don't think there's a loss in sharpness.

4k/30, Sony 11mm f/1.8, iso 100.

They advertise none. I mean you can see "something" starting to happen, but it doesn't go full stupid.

I made some videos to test.  You will see the closing in more so with iso no fluctuating and letting in more light.

MAX/MIN HD are hard stops.

Just back it off the max ND and you should be fine.

top left/bottom right have the start, but it goes away pretty quick

a couple photos i took show the same thing.
