AC Adapter for A7R3


Recommended Posts

Where on earth can I find an ac adapter for the a7r3? The way I use my camera in the studio usually involves multiple cameras into a switchable usb hub into one computer. USB powering is flaky at best and unusable at worst when switching from camera to camera. My cameras stay on all day. Anybody have a solution to this (admittedly niche) problem?

Nope- everything gets confused (unless I've got the settings wrong)

 

USB Connection: PC REMOTE

USB LUN Settings: MULTI

USB Power: ON

 

Fire up Capture One

Connect USB 2 Cable to computer: Appears to connect with capture one, but no live view and no shutter. No actual control at all.

 

Disconnect USB 2 Cable.

Restart Capture One.

Set camera to USB Power: OFF

Connect USB 2 Cable to computer: All Functions work perfectly, but no charging (of course).

 

Plug USB C Cable connected to USB C Power Supply, into camera: Choke! No control. Live view is lost.

 

This is the worst. Anybody have any other insights?

All I want is to power the camera while tethered and have all functions work. It would be extra nice if I could use my USB switcher to switch between camera on different sets.

-you know, like I used to be able to do with my a7r2's with ac adapters!

 

HELP!

Why not try something like the power output from a Watson Dual battery charger.  It should power the camera and allow charging of 2 A9 batteries at the same time.
