I'm struggling to decide on a 10 stop for my landscape lens (Canon 17-40mm F4 L).
I've bought various filters over the years and I've generally bought B+W filters. So my first instinct is to pick up this one, readily available on Amazon for $94:
But after reading up on some reviews, it seems this filter has a warm color cast
However, it is noted that the cast can be easily removed through WB settings or in post. Is there anyone there that has this filter and maybe comment on the situation?
Those reviews also mentioned great things about this Chinese brand 10-stop filter (Camdiox), which would ultimately cost me $50:
This is a significant savings, and it's better than the B+W: it has no color cast. Here's one more review specifically for this filter:
At present, it seems the Camdiox is a no-brainer, but before I jump, I thought I might try to get some feedback on this issue.
