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. While I was doing the regression testing associated with the firmware upgrade to 3.3, I decided to take a look at the battery current during senor cleaning, which I’d not… [Read More]

Yesterday, at the end of a post about my battery current testing methodology, I showed you my new technique for relatively high-speed dynamic measurements. Today, I’ll show you what happened… [Read More]
