Only a couple of weeks ago when Sony issued firmware updates for many of their lenses, Sony today has released firmware updates for many of their popular mirrorless cameras. The updates mainly address issues with overheating as well as fixing the “star eater” problem that was introduced in a prior firmware version, as well as various other stability issues. Basically, the star eater issue involved the Sony cameras’ noise reduction algorithms incorrectly identifying stars in the night sky as noise, and as a result, removed them in images. This has not made the photographers in the astrophotography community particularly happy.

In addition to yesterday’s firmware update for the a9 that fixes problems with the camera’s overheating indicator Sony has made new firmware versions available for the Alpha 7R II, 7S II, 7II, a6500 and a6300 models.
