According to a source from Zeissrumors.com…
“There will not be a digital rangefinder from Zeiss. However, a Sony EVIL（Electronic Viewfinder Interchangeable Lens）with Zeiss licensed lenses will surface around the Q2 of 2010. Your source was wrong!â€
SonyAlphaRumors has more details which we will post tomorrow (We have to wait for a last confirm).
