I have had a day of updating my cameras' firmware. I have just completed the update of my A77 to version 1.05. In addition to auto lens corrections for a number of additional lenses, including the ZA 85/1.4 and ZA 135/1.8, the camera is now a lot more "snappier" (no pun intended!).
The camera now starts up and in particular, shuts down much faster.
I know that there are those here who like to knock firmware updates (sorry Jono!) but I always try to up date my cameras as soon as I have the time and I for one can usually see a difference, before and after updates.
