Am about to go travelling and am looking for best camera companion (as happy taking landscapes as portraits). Have a 1Ds but its way to heavy to lugg around in a backpack, also have some good lenses 28-105 and 17-40 - both pretty heavy. As the 1Ds is too heavy to travel with I'm considering either a low end Canon DSLR say a EOS 450D body with my existing lenses, or going for a G11. Any comments on comparible picture performance on such set-ups? I'm after full manual control and an optical view finder in a light weight package. Have looked at non Canon alternatives like the LX5 but couldn't live with an electronic view finder. Any suggestions?
