Does anyone have experience here? Is it possible to use both the W1 hood with an 82mm UV filter, or is an option to use the 82mm-to-86mm step ring and then add on the filters at 86mm (ouch-expensive)? Finally, anyone had any luck with a circular polarizer and this lens? I really appreciate input, since I will soon have this lens I've lusted for a long time. Any general comments and/or Distagon 21/2.8 experiences are most appreciated. Thank you in advance.
