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’ve been telling you all about what I’ve been finding out about the a7RII battery draw under various conditions. It’s time I showed you how I’m doing the testing. Warning:… [Read More]

Sony a7RII shutter operation
I reported here on a7RII battery current draw measured statically. I have been working on developing ways to do dynamic measurements. I’m not there yet; I have been momentarily stymied by the camera’s apparent need for a low-resistance power supply when powering up, and I am having trouble providing such a low-resistance voltage source and… [Read More]
Sony a7RII current draw
There have been some complaints about the Sony a7RII battery drain when turned off. There have always been complaints about how fast the camera drains its pint-sized batteries when the camera is on. So far, the discussions have been usually qualitative, and, even when quantitative, not reproducible. I thought that there was probably a way… [Read More]
Cruising with the Sony a7RII – summary
The spirit may move me to comment on one or two narrow aspects of my photographic journey from Sitka to Seattle, but I think it’s time for me to summarize my experiences. If you want to start this report from the beginning, look here. A little context: as I said at the outset, I eliminated… [Read More]
a7RII operation with highly active subjects
I have tested the accuracy of the Sony a7RII autofocus for static subjects; the results were impressive. I have used the camera for many actual photographic people shots. On the whole, the autofocus systems (I say systems, because there are a dizzying number of modes and sub-modes) have performed their task with remarkable flexibility and… [Read More]
