I was an early adopter of the m4/3rds ‘compact’ system buying a Panasonic GF-1 with 20mm lens pretty much as soon as they became available. It promised so much. It was to replace the Canon G10 that I owned and carried everywhere as a recorder whilst on location with the LF gear and as a better quality snapshot camera. I briefly owned an EP-1 when they first became available but the AF was so horrible I returned it within 48hrs (see later for a revisit with better results).
