I own the 1d mark III and the 1ds mark III. i am thinking about upgrading my 1d mark III to the 1d mark IV because i'd like more resolution when i'm shooting wildlife and sports.
but i'm wondering if the 1d mark IV could also take the place of the 1ds mark III?
how does the IQ and performance at higher ISOs stack up between the ID mark IV and the 1ds mark III?
thanx,
ed rader
it seems like everything is slightly better and then there's video as well if that interests you.
