Sony A7C USB-C shutter

[ThijsPe]

Hi,

I own a Sony A7C and discovered the joy of creating timelapses a couple of months ago. Until now, the internal intervalometer has served me well. I recently wanted to use my DJI RSC2 to do motion controlled timelapses. However, it seems it is impossible to trigger the shutter through the USB-C cable. I have read online that other wired shutters are also not working with the A7C. Although, triggering the start of movie shooting does work.

Is this something that can be added in a firmware update, or will the A7C never be compatible with wired external shutters?

Kind regards,

Thijs

Hi Thijs,

Since tethered shooting is possible via USB-C the camera can be controlled via USB.
So from camera side everything is find.

But the of course the remote control devices need to support the correct protocol.

So it's up to the manufacturers to implement the correct code, so that the camera can be controlled.

Cheers

Peter

I have to respectfully disagree – I purchased an A7C and an A7III. 

An intervalometer plugged into the USB-Micro port on a A7III works as expected. The same intervalometer plugged into the USB-C port via a USB-C to USB-Micro adapter on the A7III works.

The same intervalometer plugged in with the same USB-C adapter DOES NOT work on the A7C when plugged into its USB-C port.

Now if I take my Logitech USB-Mini mouse or an IBM Trackpoint Keyboard or one of my many portable HD's, SSD's or USB Flash drives and use those through various adapters, but at the end of the chain it uses the same USB Micro to USB-C adapter, into a PC or Mac they ALL WORK. 

The rule is "USB is USB is USB" at the protocol level. After all, it is a standard.

Speeds may be different, their ability to supply more amps might be lower or higher. But the *protocol* that is transmitted across the wire is that same, thats why adapters work across all the various plug types even for "complicated" devices like HDD / SDD / NVME / external sound DACs or MIDI (like for musicians / USB microphones).

The only conclusion I can draw from this experiment is that Sony has either disabled third party devices and forgot to inform them or, is doing something untoward. After all, they also ust killed the Software SDK that they have provided all this time.

I hope they arent becoming all uber-proprietary and joining the Dark Side. 😤

Hi guys, the only guaranteed remote I could find on Sony support page is this one: https://support.d-imaging.sony.co.jp/www/cscs/accessories/compatibility.php?area=eu&lang=en&mdl=ILCE...

and it is not USB, so I think this is why yours is not working properly.

Yes but its just a remote.
Has anyone found a real solution to this issue? (and not through a computer).
Does a bluetooth intervalometer work properly for +30 sec exposures for the A7C? Any android app that can connect to the A7C and shoot +30 sec intervals?
I have searched extensively online without a real result... Yes there is some equipment like the polaris tracker and some specialised panorama tools that seems to work. But its not the solution I have in mind..
