So are you saying that when you are shooting in M mode with auto ISO, its really not manual at all because the camera is imposing it's exposure decision upon you via its adjustment of ISO? (If you change shutter speed, for example, it'll just respond with a concomitant shift in ISO.) And what you want is to be able to modify the 'set-point' through EC? Makes sense (though it has taken me a while to think it through). Traditionally, there hasn't been EC in M mode because, well, it would be foolish given the purpose of M mode (to set things exactly as you want them). What Canon needs to do is come up with another name for the mode in which you set shutter speed and aperture and ISO varies, because it's not manual if there's a degree of freedom the camera is determining. Then, whatever this new mode is called, it would be just like AV and TV where you set what you set, the camera handles the setting you don't control, and you have EC at the ready. AV=you set ISO and aperture; TV=you set ISO and SS; IV=you set aperture and SS. In all modes, EC is available. And then of course, there'd still be M mode where you set all three.
I've always wondered... what do the T and the v in Tv stand for? (And of course, that's assuming the A in Av stands for Aperture, but then why should it?)

Yes. It seems to work well, but when in manual mode, with the camera setting the ISO, I'd like a way to also use exposure compensation to tweak what the camera thinks is correct exposure. Hoping Canon can add that via a firmware update, but there will need to be enough outcry first.
Umm, I think you can use exposure comp with the Mark4..umm I did
I don't know if there has ever been a camera that you could set Shutter and Ap erture and let the Camera chose film speed....I know what shutter speed I want for freezing action, I know what Aperture I want for DOF, the camera choses film speed for best exposure at my two manual settings....
Canon Mark 4's Hi ISO Noise Filter does not affect read/write speeds when set to disable, low or standard....depature from earlier versions of ESO-1's
I shot with a good friend and Pro Shooter and he said he couldn't even get close to what I was getting exposure wise...

Nill
I've seen it explained as Tv = Time Value, Av = Aperture Value

Nikon bodies allow you to stick the camera in M, set the shutter speed, aperture and EC you want, and the ISO will move up and down (between user-defined limits if you like) to support those settings.

That is exactly what I am saying. Thank you for saying it much more clearly

Do you mean "Safety Shift"...which only works in P, Tv or Av, but, not M. If so this is different as you can use M. I think you said M was good for Nikon..and that's good. I don't know Nikon and haven't the time too....guess I should have said "Canon" Cameras..

Sort of related I am struggling to get my head round cf n 1 11 (exposure mod in manual expo).
Does this just mean base the histogram on that particular exposure mode ?
Yes. Apparently there must be photographers who ALWAYS want the camera to use a certain metering mode when they are in manual exposure mode. C.Fn I-11 lets you set that fixed metering mode. When in manual (M), you will no longer be able to switch metering modes via the top button when this funtion is set to other than the default value.

Nope, I mean just what I wrote - Nikon's implementation of Auto ISO (Pentax too, IIRC) is exactly s I've described it, and it's a great idea. Sorry, it wasn't clear you were talking only about Canon bodies.
Canon's implementation of Auto ISO is getting closer (up to and including the 7D - I've got no experience of the Mk IV) but it's not quite there yet.
Truly functional Auto ISO a la Nikon really would be the icing on the cake, and if the Mk IV works this way (the ability to adjust EC is essential if you want to get the most out of Auto ISO) then that's great news.

But I thought when you were in Manual there was no metering mode, it was what ever you set apature Shutter and ISO
Ouch! I think I just cut myself on that first mallard. Sharp stuff! And either you had a huge strobe firing or the snow was acting as the perfect reflector.

Must have been the snow!
Those were taken with my 200L f2 IS + 2X TC. The IQ I am getting from that combo is truly impressive!

Well the camera still meters and continues to give you a 'reading' in the viewfinder of where your settings stand relative to what the camera is reading. To the extent that's an important piece of information to the person making decisions about settings ("where does my exposure stand relative to what the camera is reading?"), the method of metering is relevant.

Good stuff, Nick. Were any of the IF images cropped? And hows the performance of the 200/2+2x wide open?
Most of them were cropped close to 3400px ~ 3800px on the wide side, then resized to 3264px which is roughly 8MP...I think.
So yeah, they've been cropped judiciously I would say. Retains details very well thanks to the 16MP...quality MP's I might add.
The 200+2X @f4 is decent, but you can see a little bit of softness due to the 2x. Stopping it down to f5.6 tightens things up quite a bit and as you can see by f7.1 it's very nice. I was shooting at f7.1 because I pretty much suck at BIF so I wanted to give myself some margin. ! I had plently of light anyways at ISO800, so not a big deal.
