Switching orientation of 5DM3 light meter when held vertically?

When holding the 5DM3 vertically in manual mode, is there a way to have the light meter rotate to match the orientation of how the camera is being held?

Thanks.

Ummm... Orientation-linked auto focus (which is a real thing) and orientation-linked meter readout display (which I think is what the OP is asking about... but doesn't exist)... are two entirely different things!

True. But since evaluative metering takes the active AF point into consideration, and you indeed can change the AF point automatically when rotating the camera, you have the possibility of getting some kind of implicit metering adjustment there.

Afraid not.

Besides evaluative metering, all other meter modes are center point based on the 5D3. They will stay in the center for both vertical and horizontal shooting. As Anders stated, with evaluative the AF point can either stay the same or be customized to be independent in vertical or horizontal orientation.

I know it is not stated specifically in the instruction book of any Canon DSLR that I have seen, but I would expect Evaluative to take into consideration the orientation of the camera as part of the algorithm they use in determining the "correct" exposure. Along with factors like AF points selected/showing in focus, and the brightness recorded in each zone. The latest cameras seem to be effectively evaluating a very low res version of the image, rather than just a few dozen zones, so should easily pick up on the orientation of the image.

As Daverose says the other modes are centrally based, so orientation won't matter, with the possible exception of CWA. On some cameras the CWA pattern is/was slightly asymmetric to allow for the sky at the top of the frame. They usually put a guide to the metering sensitivity patterns in the manual, and I would recommend checking those out to be certain what the camera is going to do.

On the 5D3, like many Canons, the CWA is directly in the center. Evaluative is always weighted at what AF point you have active...and with the 5D3, you can either have the AF point be the same in horizontal/vertical orientation...or be independent (it will remember what was the last AF you selected in the orientation you switch to).

This article goes more in depth about the evaluative metering algorithms in current DSLRs:
