<<While you do have to worry about vignetting with thick filters like B+W, slim filters, like Nikon's L37c, do not cause vignetting at all! Other filter manufacturers also make slim versions of some of their filters. Of course even Nikon's polarizer is thicker and will vignette the 24.>> Will B+W's slim circular polarizer vignette on the 24/2.8? My 62mm slim circ. pol is 5mm thick. Thanks, Dan
