This is precisely how I want it to be

Set aperture and shutter, put ISO in auto. Wouldn't you want to be able to apply EC so when the camera decides what ISO to use it respects your +/- EC?

Don't know how other people shoot, but this is in fact the only time and the only way I'd want to use auto ISO--when I have a particular aperture and shutter speed I want in fluctuating lighting conditions and don't care what ISO is used. Auto ISO in other exposure modes is 1 too many variables to keep track of for this feeble brain of mine.

Oh yeah? How exactly does it work in M mode for example?

But how can it "respect" your +/- EC in M mode? How would the camera know whether you want the aperture or shutter speed changed? I can't wrap my brain around this! Totally confused!!!

By changing the ISO! In M mode, you'd set your aperture and shutter speed, and the ISO would go up or down depending on the EC you set.

Didn't you have a darkside camera before ? . I'm at work I can provide detail example once I finish with work. In general the SS and aperture value don't change but the ISO will go up and down depends on how you EC it. I think Canon implementations is still half baked unfortunately.

Hmm...I guess set the aperture and shutter in M mode, which could be + or - relative to center. Then the Auto ISO would kick in to honor that setting then? So if the scene becomes a little darker, the ISO will be raised, keeping the relative + or - position.

Yeah...that would be useful. But I don't think that's how it's implemented right?

That's my favorite setup right there.

That's what I'm wondering. From a few minutes searching it appears that setting exposure compensation in M mode actually skews the light meter. So if you dialed in 2 stops of EC and then forgot about the next time you used the camera all of your exposures would be off by 2 stops even though you'd been zeroing the meter.

Yeah. I don't remember being able to over/under expose in M mode with Auto ISO on. It will always force the meter to the middle. Not sure. Can't remember. I remember it worked well in Av mode though.

Anyways, sorry to go off-track with Auto ISO. I'll check this out on Monday when get the 5DMK3.

I think it's very useful if you want to have your metering the same (SS and f-stop values) but you just want to adjust the tonality of the scene (white snow, dark clothing, etc).
