ND filters and color correction filters?

[Ron Michaels]

Hey everyone,

What is the widest you can go without vignetting using 4x5.56 filters? Also, which filters do you prefer, i.e: brand, set of stops, circular, square? I'm also thinking of getting a couple of CTB filters, tiffen maybe? Any advice would be great.

Thanks again,
Ron

The new screw-on filters from Formatt, the Hitech 82mm Firecrest ND Filters are very color accurate and mix well with each other. A problem I haven't found solved in many other brands.

Anyone here use the Schneider CTB filters under tungsten? I'm thinking of purchasing the half CTB. Is there a green shift? Are they sharp? Thanks again.
