A new firmware upgrade has been issued for the A77 and is available from Sony Asia: Sony A77 Firmware Upgrade 1.04 for Windows and Sony A77 Firmware Upgrade 1.04 for Apple Macintosh.
Sony say that the firmware offers the following improvements:
- Expanded the number of automatic compensation compliant lenses: Sony SAL-1680Z 16-80mm f/3.5-4.5 Zeiss Vario-Sonnar and Sony SAL16105 16-105mm f/3.5-5.6
- Functional improvements:
- Improvement of responses
- Improvement of picture quality
- Improvement of usability
Although we’d all like a slightly faster, more useable camera with better picture quality, my experience with firmware upgrades is that it’s usually best to wait for a few days to allow any problems to be ironed out. I won’t be upgrading until I’ve seen people posting that it all works and makes noticeable improvements.
