the big jump from the old Rebel menu system to the Pro menu's.
For the iso, I went in and assigned the SET button on the job wheel to allow me to re-assign the iso on the fly when taking photo's. So I can press the set and then turn the top scroll wheel to re-assign the iso. So I have full control in manual of the shutter, aperture, and iso. This is a big improvement for me over the 50D that I had.
Out of curiosity, how do you find the learning curve going from your T2i?? The layout of all the controls is totally different with this camera. There is quite a bit to get use to, but I feel like they have put more thought into it. I have my weekend cut out for me to go though the manual to figure out how to get the most out of my new AF.
I'm finding it not too bad actually. I've had the camera a couple of days now and I read the manual to sleep every night
but Im more of a hands-on learner than reading the solutions, so I typically go through each menu over and over memorizing the options and trying them to see what happens
There are still a lot of settings that I have no clue about yet, but I am learning as I go. So far I'm in love with it
just waiting for a nicer day to be able to finally shoot it at 100 ISO - I want to see how great the quality can be 
haha the sheer difference in weight between the two is staggering, though. But I got used to it in a few minutes (until I mounted my 85 f/1.2) - and now when I pick up my T2i for comparison, it feels so light its like its hollow :P I like the grip and weight of the 5D III, it feels just...better. Stronger.
