All the bells and whistles aside (eg: Video/weather sealing/ high ISO performance)
What camera would you rather have for FF/ 100-400 ISO performance, functionality and speed?
I have not used a 1dsII and am curious how the IQ stands up to current bodies in the 100-400 ISO range.
I shoot low light and sports with a 1DIII so I don't really care about ISO800+ on a new body.
I want a FF cam and a used 1DsII is cheaper than a new 5DII...
