<That would mean I need to use either a Nikkor polarizer (which would prevent the use of the lens hood) or, if I can find one - and if it's thin enough - an ultra-thin. (Hoya makes some ultra-thins, but AFIK, no thin polarizers.)> There are several ultra-thin and extra-wide circ pol options, but you can also simply buy a step-up ring and a filter two sizes up from your lens thread too. regards, Henry Posner/B&H Photo-Video http://www.bhphotovideo.com
