No big surprises... Olympus PEN E-P3 Preview: 12. Comparedto...(Raw): Digital Photography Review Be careful, the E-P3 can be set on iso12800 (not that I intend to use it in practice), but the G3 and x100 (examples that I wanted to compare) do not go that high. No real change vs Epl2. Quite comparable to the G3. I am thinking the key reason to upgrade from my E-P2 is overall speed of operation (focussing, shorter blackout, better VF-2), rather than real change in sensor (using RAW). These are benefiting the Epl3 as well....am I patient enough to wait?
