This is a continuation in a series of posts on power consumption in the Sony a7RII. The more recent incarnation of the series starts here.
I’m getting ready to wrap up this series of tests of the Sony a7RII battery current drain. I’m pretty sure I’m going to be using the techniques I’ve developed for other tests such as autofocus performance, but I’ve reached the end of what I think is useful to discover about the battery drain per se.
In this post, I’ll list the important things that I’ve discovered, and link to posts with more detail on each. I will try to keep this qualitative. For those of you who like graphs and numbers, there are plenty of both in the linked-to posts.
Fortunately, the amount of power consumed by IBIS, OSS, and focusing is small compared to reading the sensor and refreshing the display.
