A step-up ring from a 58 to a 77 looks more than a little odd. I haven't yet tried a polarizer in my big lenses, but they both have drop-in filter holders (which makes using step-up rings impossible). Unfortunately they can't even agree on filter size; the A* 300/2.8 uses 49mm filters, while the FA* 250-600 wants 42mm.
At least the old Vivitar 21-35mm uses 77mm filters, so it can share anything I get for the 80-200 (although I should probably make sure I buy the thin variants, just in case I use them with a film body). And the 49mm filter size of the A* 300 lets me use some of the old filters that lived in my bag of M lenses. > i use step up rings, but mostly use my 67mm filters. when i finally get my > DA 14, i will get a few more 77mm filters and sell my 67's. i have not yet > found a need for dedicated filters for anything smaller yet. > > Herb... > ----- Original Message ----- > From: "John Francis" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Friday, August 27, 2004 12:57 PM > Subject: Re: Polarizer > > > > They're both ways to achieve a desired effect.
