Maybe other Sony Alpha 7, full frame camera owners are as indignant as I:
You forgot to include a Battery Charger!
Yes, imagine spending over 1000 GBP (1500 USD) on a camera only to find that Sony gave me the /opportunity/ to go and select the battery charger I might prefer.
They supply a USB cable + thumb sized powerbrick so you can (only) charge the battery in situ within the camera as standard.
Note: The following solution relates to Sony Alpha 7 (not the 7R or 7 Mk II)
Replacement Battery

The camera was supplied with a single NP-FW50 battery.

Unusually I found I could order some replacement batteries from the UK. I ordered 2 (for 15 GBP!!)
Mains Charger
After more eBay searching I order a 2 bay charger. From terence_camera in China. Under 12GBP including postage. Simply incredible value.
Now I have a really workable solution. Note the size of the solution compared to my iPod nano. Tiny! Tiny! Tiny!
- I can quickly charge 2 fresh batteries simultaneously
- I leave home with the current camera and battery and when it dies I have 2 more to go.
- You can easily shoot at least 300 shots from the 3 batteries and that's way above our normal daily holiday rate of 150 max.
So all is well and now we are investigating a portable DC voltage only solution for the future.
