The next Sigma DSLR will adopt the “Quattro” sensor found in the new dp line of mirrorless cameras. That was expected, but an official confirmation is always good to have in case there were people hoping for a full-frame camera or something else.
The information comes from Sigma’s CEO Kazuto Yamaki himself, in an interview given to Yodobashi in March 2014, and only recently published.
As the first camera to have the new sensor, we chose the dp because of the shockless body and the dedicated lens optimized for the ultra high-resolution capturing. Of course, we’re planning to use the sensor for the SLR SD body.
Unless Sigma wants to draw all the attention on the as-yet unreleased dp1 and dp3 Quattro, an announcement at Photokina (September 16 to 21, 2014) and a release in 2015 is a likely scenario. I’ll try to confirm it or not.
