The main control dial on the a77. Not as nice as the Maxxum 7 nor my Konica-Minolta 7D. Glad to see Sony brought back the better dial for the a99. The dials on the 7D:
You have to push the button on the top of the dial to turn it, and there are two levels. For instance, on the exposure compensation dial, the top one is for the camera, while the lower one is for the flash. Such an excellent design! On the shooting-mode dial, the lower one is for choosing single, continuous, self-timer, etc.
