I agree with the assessment above but the quality of pictures (very comparable to the D800) and the small form factor of the A7R makes it the best choice for go-getter photographers. Also, we have to take into account that the next iteration of the A7R will likely solve the autofocus issue and battery life making it hard for Nikon to beat. Finally, sports photographers know what to buy. Most of us are not sports photographers. Way to go Sony !!!!!!!!!!
