Image on top shows the current Sony A7c. The new High end APS-C camera will look very similar to it.
Another source basically confirmed what we know so far and added some tidbits (Thanks!):
- Basically, an a7c with an aps-c sensor.
- same EVF, LCD resolution
- same tilt screen
- same new menus
- only minor tweaks to a7c body
- BUT improved IBIS using smaller APS-C sensor
- New sensor
- higher resolution over current APS-C line
- same FPS as a6600 but now pushing larger files
- improved low-light performance
- reduced rolling shutter
- video specs may be close to a7c
- price similar to a7c
