Steve33 Posted April 27, 2011 Share #1 Posted April 27, 2011 Advertisement (gone after registration) Hi, I am looking at buying a polarizer to shoot some slide films. I like the effects of a polarizer on blue sky. Sorry for my ignorance but should I buy a linear or circular filter? Since I can't see the results of the polarizer as for a SLR, should I go with a linear? Thanks. Steve Link to post Share on other sites More sharing options...

tgray Posted April 27, 2011 Share #2 Posted April 27, 2011 Buy a linear one. A circular one is usually recommended for autofocus SLRs so the autofocus can operate properly. It can also affect the metering if I recall correctly. Since your M doesn't autofocus, it's not an issue. The metering won't be affected either due to the way M's meter.

budrichard Posted April 27, 2011 Share #3 Posted April 27, 2011 Leica makes a Polarizer that has a swings up to the rangefinder window that allows you see the effects and it fits a number but not all of their lenses. I have a couple and they work fine.-Dick Link to post Share on other sites More sharing options...
Guido Posted April 27, 2011 Share #4 Posted April 27, 2011 Personally, I just put on a standard non-Leica circ polarizer and rotate the filter while watching the exposure meter display to find the desired position. Link to post Share on other sites More sharing options...
lincoln_m Posted April 27, 2011 Share #5 Posted April 27, 2011 Steve, I bought this a few years ago. Kenko Rangefinder polarisers | Robert White Photographic Ltd But apart from dropping the exposure down by 2 stops I've never seen any difference on Velvia slide film. I get a better effect by underexposing a little say 0.5 stop while getting that 1.5 stop difference in shutter speed or DOF. My experience with filters on Leica lenses has been generally poor with a feeling that one is putting a cheap piece of glass in front of a very expensive and high quality lens. So now I don't even use a UV filter as they are able to catch light and cause flare. I do use the lens hoods though, they do work great. If you are local to UK perhaps we can do a deal for my E39 screw filter polariser if you like or even a loaner to try it out. As I said I don't think they are worth the -2 stops, but perhaps I have used it when the sun is high 10am - 4pm? Regards, Lincoln Link to post Share on other sites More sharing options...
Steve33 Posted April 28, 2011 Author Share #6 Posted April 28, 2011 Thanks to all for your replies. I think I will go with a linear polarizer as suggested. Never thought to look at the meter readings for a circular polarizer. Good idea. Link to post Share on other sites More sharing options...

Never thought to look at the meter readings for a circular polarizer. Good idea. It will work for a linear polarizer too. On a camera that doesn't need a circular polarizer while metering that is.

Double Negative Posted June 21, 2011 Share #8 Posted June 21, 2011 Maybe this will help explain the options... Polarizers and the M System. I have the Leica Universal Polarizer myself; works rather well. Link to post Share on other sites More sharing options...
