PMA 2010: Sigma DP1x and Sigma DP2s video preview. At the PMA 2010 preview, Sigma – as well as showing its five new lenses – also had new DP-models on display. The DP1x and DP2s make tweaks and improvements on the previous models. Although the sensor remains the same 14MP FOVEON X3 CMOS, improved autofocus (AF) in both the DP1x and DP2s is now swifter. The rear buttons are also  labeled white on black for easy reading and there’s a slight adjustment of layout too. The DP1 takes the True II processor as also found in the DP2 and adds a Quick Set (QS) button.
