On April 10 Sony released firmware version 3.0 for the Sony α7R III and α7 III. The update gives α7R III and α7 III users new AF capabilities as well as an advanced built-in intervalometer for time lapse.
This new software adds a built-in interval timer, enabling photographers to easily capture and create time-lapse movies. The new feature can be set for anywhere between 1 and 60 seconds, with a total number of shots from 1 to 9999. AE tracking sensitivity is available to be adjusted to “High”, “Mid” or “Low” in order to reduce changes in exposure. Sony also added a playback function that allows you to actually get an in-camera playback of the time lapse instantly.
