Sonyalpharumors has yet more A77 specs updates:
- 1200 zone metering
- Smart teleconverter function with 1.4x and 2.0x option
- Built-in GPS
- Battery life with over 500 shots
- ‘Smart teleconverter function’ will mean an in-camera cropping function; you get ‘telephoto’ by seeing less than the full 24MP of the sensor.
- I would guess this function is also necessary to achieve the 12 frames/second continuous shoot, which you’ll only get in one of these modes, not at the full 24MP. Other Sony Alpha such as the A35 work in a similar way.
