I set it to actual focal length, except when using a teleconverter, in which I'd use the focal length taking the TC into account (e.g. a 200mm lens with a 2x TC would be set to 400mm). Looking at your post and Marcus's - I have to say that I'm setting it for a lens / TC combo based on intuition, not on documentation. But the old saw about teleconverters is that a lens with a teleconverter attached functions in every manner as a lens whose focal length and speed are multiplied by the TC. But there are those who disagree with that assertion WRT depth of field. > > --Polerizers.

Asking as i rarely use > filters and i wound up bracketing a lot. Shoot what the meter gives you. That reminds me of a test I have to run. Last winter I read something by Ansel Adams where he said the 'filter factor' for a polarizer was the same regardless of the setting of the polarizer. So - sky dark, sky light, make the same adjustment. He was talking about using a hand held, non-TTL filter. I've been meaning to see if that is how TTL filters truly respond. Now that the sun is shining again I'll have to test that one out. - MCC -- - - - - - - - - - - - - - - - - - - - - Mark Cassino Photography Kalamazoo, Michigan www.markcassino.com - - - - - - - - - - - - - - - - - - - - -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
