The lens provides the basic distortion correction data (just like Pentax DA lenses do for the K7 btw). Other than that they have AF-related firmware and transmit basic lens data. It's actually less information than DA lenses provide (since they also provide MTF data for the MTF program line, which 4/3rds doesn't offer). And yes, an ultralight, ultracompact lens will be all plastic. Most of the market won't pay the cost of the 17 if it was metal. -- M.
