Definitely a very sweet set of upgrades for my camera. I'm really looking forward to this becoming available!
I just don't get the increase in minimum shutter with auto iso. I have always set my shutter speed range in Av mode and using Auto-iso, that way I choose my aperture and my shutter never drops below what I choose, say 1/2000s, and auto-iso keeps my exposure correct, how is this different?
When you restrict the range of available shutter speeds, that applies in Av mode, Tv mode, M mode, etc. This new setting will apply only in Av mode, with Auto ISO set. If, like me, you have that shutter speed range restriction for fast action applied only to a C# setting, then this particular additional feature might not be of that great a benefit to you.
BTW, anybody else notice the 5DIII metering does seem to be influenced by the position of the AF point? I know that this is a feature of the 1DX not documented as available on the 5DIII, but if they share the AF system...
Will run some tests shortly and start a thread if not just my imagination.
In Evaluative metering mode, the metering is always weighted toward the selected AF point. That's true on the 1D X, it's true on a Rebel/xxxD.
What the 1-series bodies have that lower bodies do not is Spot metering linked to the AF point.
Given that the AF system is supposed to be the same as the 5D3, I wonder if we can expect a bumper update for that too?A similar upgrade to the 5D Mark III would be great, but there may be technical limitations we are not fully aware of.
There may be technical limitations based on the more sophisticated metering system of the 1D X. It's also quite likely that there will be marketing limitations, that would preclude some or most of these features from trickling down, at least in the short term (possibly with a 5DIV).
