According to two of our sources Sony should unveil the new Sony A850/900 firmware update by end of the next week. It’s Christmas time and Sony wants to push the full frame camera sales. Would be nice to see some price drops too 😉
We only know that exposure compensation, AF performance will be improved. One source said also the image quality will have a major improvement (but that hasn’t be confirmed by other sources). We don’t know yet if also the A700 will get a firmware update. If you know something please contact me at email@example.com. Thanks!
P.S.: We expect the next Sony Fullframe camera to be announced late 2011/early 2012.
