For what i'm concerned, the camera can do so much, it can calculate the exposure, calculate exposure based on the parameters of the min shutter THAT YOU SET, and there you go...
I guess my background (which is a lot about usability) has made me look deeper for the ways that systems can help.. whether others want to use them is up to them, but I can guarantee that I could spec a system which would help some users much more than the current system.
It feels like the old "programmer spends 90% of the time making a system and then 10% of the time making it usable".
If Canon asked their customers what they want or took notice of feedback (I sent in feedback 3 years ago when I got my 5d2) then this thread and all of the other 5d3 auto ISO threads wouldn't exist.
For me, it's not a lesson for the users in how to live within what we're given, but for manufacturers to listen to their customers needs and satisfy them, especially in the face of competition (not just Nikon) which seems to have got it right.
It could be said that canon did listen to their customers... people wanted better ISO, canon gave it to them, people wanted much better AF, they gave them the best AF they have, people wanted more customization, no more MP, 100% VF, people wanted horizon level, people wanted weathersealing, people wanted more usability, canon gave them all of that and then some. Canon gave everything people wanted yet people still aren't happy, ad regarding the feedback, give feedback, but all the gripes are about new features, the new AF, the new implementation of the auto ISO... in the last, lets say 4 years, that i've even dared to use auto iso, because before that, with the 30d and such, ISO was so awful you didn't WANT your camera to bump up past ISO 1000 if you can help it. Now it isn't as much as issue. But in that time, I would guess auto ISO maybe cost me a handful, ok, maybe a dozen images total because shutter was too slow for the scene, but in the end, I take responsibility for not having the camera in full manual or Tv to make sure that wasn't an issue. Then again how I shoot isn't the same as you, so...
