… and it does use Leica lenses (quote from Wired):
“The retro body is a rangefinder camera, which means manual focusing using the matched images familiar to anyone who has used a film rangefinder. It even takes Leica lenses, making it a passable alternative to Leica’s own M8, and cheaper at $3000. Weirdly, Epson hasn’t upped the pixel-count of the CCD sensor — it still holds just 6MP. This could either be fantastic news (a new, ultra low-light sensor) or terrible (old, 2006 technology).”
