I've been looking at this camera mainly because it's meant to be so much lighter than digital SLRs (I'm finding my Canon 400D is v heavy with lens attached). Will be interested to hear what others think - the reviews of the G1 are good although there aren't many lenses available yet. Pudding, there's loads of reviews of this camera if you do a Google search which explain the various technical terms eg
