[Questions] RAW 2,5K / Limitation / ETTR or Dual ISO ?

[WorkFl0w]

Hello everbody.

I got a brand new 5D Mark III with a 14mm L and the 16-35mm L also the 24-105mm L
for a very cheap price of 3600€ from a guy that doesent have any knowledge about
the price .. so i´m more than exciting to use all of the stuff.

But i have some questions about ML-RAW.

What is the CF card MAXIMUM of the 5D Mark III ?
i mean the limitation of the write speed on the
CF card. The SD card have some limitation of 20-30mb
i don´t know the exactly ammount. so is there any
restriction ?

Also is the cropped 2,5K Raw better than the 1K Raw ?
Is there more detail / sharpness or why it is in Magic Lantern ?

Get i more pictures when i turn of the global draw and set the
picture quality to S2 (i use this on my Canon 60D) ?

There are some things that i can use in Magic Lantern
so there is Dual ISO, ETTR and the normal Raw build.
What is the perfect way to get the most of my camera ?
Is ETTR better than the Dual ISO or when is the first
option better than the second ?

And maybe is there a build with the full audio controll ?
I only have 2 options in the audio tab on Magic Lantern.
Maybe i missed something because there are so many things
out right now. Tragic Lantern, Alpha, Nightly Buid and and and.
So i´m a little confused.

I hope someone can help me out with this amount of questions.

Not sure somewhere between 110 and 130, but I think Canon states that CF card controller speed is much higher.

Cropped video is much better

On 5D3 it is best to set image quality to to RAW

ETTR and Dual ISO are two different things and they can be used together.
