My stupid 1D4 does what you want the 5DIII to do. What is needed to improve the implementation is a minor menu change - although for me it isn't a problem
PS The implementation in my stupid 1D4 looks to be the same as in the stupid 1DX. Still better a stupid implementation than none at all
no, not at all, the 1D4 does not do, what I would like the 5D 3 do with regards to Auto-ISO.
But more importantly, you got the wording wrong!
Stupid Canon is implementing Auto ISO in the 1D X in the same stupid way as already in the 1D IV and 1D III before. Without any improvements to either functionality or the awkwardly stupid ergonomics.
It is still CTRL*ALT*DELETE*CUSTOM FUNCTION*SAFETYSHIFT*DIRECT-PRINT! STUPID. ;-)
If you are happy with that, good for you. Me ... I am not.
I understood you wanted to control the shutter speed, aperture and use autoiso with EC as well.
Is that not what you want to do??
With fixed AV and TV how would you want the camera to behave when iso gets to the minimum or the maximum then?
yes, but that is not all! In P and Av I additionally want the cam to take focal length (also wioth zoom s!) and presence of an (activated) IS into account ... to automatically determine a suitable minimum shutter time with respect to avoiding camera shake induced blur - unless I specifically set a shutter time as lower limit.
And I want it implemented in an as user-friendly fashion as in the Nikon D4 and D800!
There you can EITHER set a min. shutter speed OR set min. shutter speed to AUTO .. .and the cam will determine a suitable lower limit based on focal length in use (1/x) AND if desired, this algorithm can then be further finetuned towards using somewhat longer times (if the user trusts his steady-holding technique) or towards somewhat faster shutter times (if one feels a bit shaky ... ).
This is much more complex to describe here than to actually use the feature on the Nikon. Just read up in the link to the dpreview D800 review provided in one my previous posts.
If implemented in such a way, the Canon 5D3 would be egonomically even superior to Nikon D4/D800 in thei sregard ... because on the 5D3 these settings would be stored as part of the overall camera-setup in the 3 Custom-modes [C1...C3] on the main-mode dial from there the can be recalled instantly. E.g. I routinely store a "tripod-photography setting" under C2 on my 7D. In that setup, I would set a much lonfger minimum shutter speed for Auto-ISO than in setting C3, shich is my "action-oriented setup" (handheld).
Those custom settings C1/C2/C3 on the main mode dial are one area where Canon's implementation is far superior to Nikon's concept of storing user settings in 2 separate "storage banks".
On Canon 1D/s/X cameras there is no mode dial, so this does not apply to them and makes operation somewhat different - and less efficient than on 5D II//III and 7D/60D. But this is admittedly a matter of personal preference and what you are most used to.
