Re: Easy: large CMOS sensor, large pixels and good electronics

I wish Canon let us adjust the ISO between ISO 3200 and 6400. It's as
if they added "H" for marketing purposes.

That's easy: Shoot raw and underexpose and you will automatically have > iso 3200. Compared to a camera setting you don't loose much since 14 bits should be enough to represent the information available in the raw file.
