5D2 with linear polariser...?

I'm looking to add a 105mn pola to my lee kit.
When using my lee kit I always use manual focus, so the issue with auto focus isn't going to be a problem. However I've heard that some cameras have exposure pronlems with linear polarisers, so I wondered if anyone with a 5D2 has any experience of this?

Thanks.

Has no one got any experience of using a linear pola on a 5D with manual focus....?

OK, I have a 5DII and both linear and CPL that fit all my lenses, but I must admit I've never tried the linear. I was going to, but never got around to it. I'm out of the country and away from my gear until next week, but if no-one else chimes in PM me next week as a reminder and I'll test it out.

Linear polarizer may affect your metering.

About halfway down in this link...

Megapixels and high ISO are a digital photographers heroin. Once you have a little, you just want more and more. It doesn't stop until your bank account is run dry.

From what I've read depending on the position of the polariser will depend if the metering is over or under, by how much I'm not sure. I wonder if using live view will mean you can manually adjust for this?

I've also read that some Pentax DSLRS allow AF with LPLs.

Since the metering is performed by the sensor when in live view, that would be the safest way to use a linear polarizer. AF and AE will work just fine in LV.

Live View histogram will be true metering, while non-Live View might be affected if a lot of the image is polarizer-filtered, but that can fixed by chimping!!! I always preferred the stronger effect of the linear filters but used MF and checked exposure afterwards...

Ok, so I have read stuff about linear vs. circular and since I have both and this thread came up I thought I'd actually try it.

All shots are with a 5DII on Av, matrix metering, one shot with the 24-105, EXIF's should all be intact. I did a bit of testing and decided these shots were representative of what I found.

The first 4 were hand-held without a tripod. The second 4 were on a tripod and I de-focused each time before re-focusing and taking the shot. I also tried all shots with min and max polarizations (although they may not be 100% the same) In fact shots 1 and 2 probably had some polarization variation (there is a 1/3 stop difference in shutter speeds). I think the others are close.

Results:
Both AF and metering worked just fine with the linear polarizer.
My high quality B+W MRC CPL ($130) filter flares much, much less than the lower quality B+W non-MRC linear polarizer ($67).

I stick by my assertion that one should either by cheap ($20-$30) polarizer or a top of the line multi-coated filter. I probably wasted $30-$40 with the B+W linear polarizer, but that's a separate topic.


Ok, two at a time. First two hand held, no polarization (I think there is a bit of difference since there is a 1/3 difference in shutter speeds but exposure is the same).

Linear on left circular on right.

These are with max polarization. Linear of left, circular on right.

On tripod, no polarization.

The sun it at about 60-70deg and with no shading it is shining on the polarizer. I guess I should have taken a shot with shading to see how much the multi-coated filer was flaring, but clearly the cheaper non-multi-coated filter is worse.

Oh, and I just remembered I did stack it on top of a B+W MRC UV filter, so I'm sure we can all argue about the validity of that!

Anyway, linear on left, circular on right.

Same as above with full polarization. Looks like I moved the camera on the CPL plot so it's not as sharp. Remember I de-focused all of these before re-focusing and pressing the shutter.

Again linear on left, circular on right.
