Sony A850 compared to other "compact" full-frame DSLRs
The chart below compares the Sony Alpha A850 with the A900, the Canon 5D Mark II and the Nikon D700. What we've done below is presented something of a hybrid comparison between these three models. A red cell means that a given camera performs below the others, a green cell means that it performs better than the others, and a yellow cell means it falls between. In cases where two cameras share a superior capability, both cells will be colored green, etc.
