This is the Pentax full frame DSLR camera (behind glass)







Adorama posted on their website several pictures of the upcoming Pentax full frame DSLR camera. The prototype shown on displayed at the 2015 PhotoPlus Expo in NYC has more details than the previous version released few months ago (see this image and this prototype):

 



There is still no information on the exact specifications or model name, but you can clearly see the twist-out (or flip-out) LCD screen.

Update: more pictures of the Pentax camera prototype from the PhotoPlus Expo are available here, here and here.
