<i>Can't really see how the two can be considered at the same time since they have virtually nothing in common: 1"
sensor vs APS-C, zoom lens vs fixed focal length</i>
<p>
They are very similar, sony has focal length of 24-70 but the GR can be cropped to give a working focal length of 28-70
easily(it even has built in 35/50 mm crop modes), very similar size, sony fast AF vs Ricoh snap focus, similar flash
capabilities, Sony's EVF is probably the biggest difference between the two although you can buy an optical finder for the
Ricoh. Can't comment on Video.
