Hello!
Coming back to landscape photography, my owned filter-gear is mostly not usable anymore. My fault, a damage from wrong storage and old age/warmth killed almost all of them.
(Only some grey-graduated and color filters from Lee are usable. But non of the firecrest filters and screw in filters.)
I´ve read, some new companies entered the market. Some of the big old players like B&W, Lee are still on market, but some test suggest to invest money into other brands.
There are certainly a lot of ND filter experts out there in Canon rumor forum.
I´ll ask you for your advice which company to choose.
I owned screw in filters (B&W) and older Lee-Filterholder 100mm (>10a). Canon lenses with 82mm, 77mm and 67mm. The filteringfactor were 0.9, 1.2, 2 (?) an 3.0
Some of the filters had heavy color casts, which I do want to avoid now.

Thanks a lot
