Polarizer for summicron 50 39 mm

My choices are Hoya linear or bw circular. I know manual focus lenses don't need circular. Is there any advantage on me going with the BW ? Thanks.

What cameras are you using them with?

Cameras that use a beam splitter in the metering system require a circular polarizer.

M3.

As your M3 is not an SLR (unless it's a lot different than my M3!) you'll have to remove the filter to look through it to get the rotation right. I recall that years ago some polarizers had numerical scales or marks around one part of the filter and an index point on the other so you could adjust, note the proper number or mark, then put the filter back on and then set the filter appropriately. As there's no meter in your camera, no need to worry about linear vs circular IMHO.

ok was just wondering if going circular had any significance even with the M3. Thanks for the replies.
