From where did you get it ?

Keep in mind that we can't read focal length and IS status outside LiveView.

I'm not well placed to tell what is possible and what is not, but inside and outside LiveView, the camera calculates the shutter speed and the according ISO (on Auto ISO mode) using the focal lenght that is set (even on zooms) when pressing the shutter button. So I guess that the focal lenght is a readable data. And probably the IS status too.

[evaluative metering]

When on evaluative metering mode, you want the picture to be exposed depending on what is into the frame when you shoot.
But in that mode, the camera locks the mesure when you make focus, even if you adjust the frame after focusing.
So when you focus on something and reajust your frame, the exposure that is used is te one that was mesured on what was on the frame before adjusting the frame. That's just crazy.

On evaluative metering, the exposure should continue to be calculated untill you full press the shutter button to match the scene that is on the final frame (like it's done on the center-wheighted average metering mode).


When on spot metering mode, what you want is the exposure being calculated on what you pointed when focusing (if that's not what you want, you just use AE-lock button).
But in that mode, the camera continues to mesure the exposure while you're adjusting your frame after having focused.
So the exposure is spot-mesured on the random item that is under your collimator when you full press the shutter button after adjusting the frame. Still just crazy.

On spot metering , the exposure should be locked by default when you locked the focus.

Another workaround would be to set in some ML settings that IS is "activated" (whatever it's true or not), so ML could calculate the exact shutter speed / ISO according to that.

For the moment, the (simple) algorythm that calculates the ISO in Auto ISO mode do not takes care about the stabilisation being or not being activated on the lens.
So when it is activated, the ISO setted by the camera is something like 2-3 stops higher than needed. That's infuriating.
