#5. The 1Ds IV maintains its good results while providing far more resolution
Differences in noise between the 1D III, 1D IV and 5D II samples up through ISO 6400 are minor and insignificant to my eyes – all 3 DSLRs produce impressive results. Thus, higher resolution wins at final output. The 1Ds IV maintains its good results while providing far more resolution than the 1D III without an increase in sensor size. The 5D II has the sensor size advantage over the other two cameras.
