Sony A800 with 15.2MP
 

The first list looks like someone took version 2 and added in a wish list of features. I don?t see how Sony could possibly stuff a 100% viewfinder and their quick AF Live View into one pentaprism. It?s just impractical from a design standpoint. Sony?s quick AF Live View requires a second sensor in the pentaprism to capture the image for Live View display. That?s a lot of hardware up around the viewfinder. I could see one or the other in the A800, but not both.



According to a curious post over at Photofan.jp, Sony is readying an Alpha A800 DSLR (mockup pictured) with a 15.2 megapixel sensor, an ISO range of 200 to 12,800, a new high-speed sync flash, 23 total AF sensors, a fresh metering / AF sensor tracking system and inbuilt WiFi.
