How to tether the Sony α7 III to your phone

1
Set up the α7 III
MENU → Setup → USB Connection → PC Remote. Disconnect any smartphone connection (Imaging Edge Mobile / Creators' App) first. Lengthen auto power-off so the camera stays awake while tethered.
2
Connect it to your phone
Open CloudTether, tap “Connect a camera” and plug a USB-C cable from the α7 III into your iPhone, iPad or Android phone (a Lightning iPhone needs Apple's camera adapter). Wi-Fi tethering isn't supported on this body — use the cable.
3
Choose where the shots go
The “Send its shots to…” sheet shows where the camera is sending. Keep shots on the phone, or add Dropbox, Google Drive, a client gallery or an FTP/SFTP server — a shoot can send to several at once. Take a test shot.
4
Shoot as normal
Every frame your α7 III captures is copied to the phone at full resolution — JPEG or ARW RAW — and delivered while you keep shooting. Each photo uploads from the phone once and goes to every destination.

CloudTether Send its shots to sheet after a camera connects over USB, with a test shot delivered to Dropbox and Google Drive — When the camera connects, pick where its shots go and take a test shot.

Every Sony Alpha body runs the same CloudTether code, which we've verified over USB on a ZV-E10.
In the camera's PC Remote settings, set Still Img. Save Dest. to PC+Camera so every shot is also written to the card as a backup.
Rated send isn't available over Sony tethering — in PC Remote the phone can't read ratings from the card — so every shot is sent.

Every α7 III frame at full resolution — ARW, JPEG or both

JPEG only: leave RAW on the card to save mobile data

Sony α7 III tethering FAQ

Can I tether the Sony α7 III to my iPhone or Android phone?

Yes. The Sony α7 III connects to CloudTether on iPhone, iPad or Android with a USB cable, and every photo copies to the phone and on to your destinations as you shoot. It's supported by the protocol but we haven't tested this exact body yet — every Sony camera runs the same CloudTether code, which is verified on other Sony bodies, so try it before a paid job.

Which USB setting does the α7 III need for tethering?

MENU → Setup → USB Connection → PC Remote. Disconnect any smartphone connection (Imaging Edge Mobile / Creators' App) first.

Can the α7 III tether over Wi-Fi?

Tether this body over USB — its wireless tether is limited or unavailable, and Sony's send-to-smartphone mode isn't a tether.

Does CloudTether transfer ARW RAW files from the α7 III?

Yes. CloudTether copies the original ARW RAW, JPEG or both, exactly as the camera writes them. Shooting RAW+JPEG? Turn on JPEG only to leave the ARW files on the card and send just the JPEGs — the fastest option over mobile data.

Can I send only the shots I rate on the α7 III?

No. Rated send works over Canon and Nikon tethering only; over Sony tethering every shot is sent. Use JPEG only to keep uploads light.

How fast does the α7 III tether to a phone?

We don't have enough α7 III transfers in our logs to publish a figure. As a guide, a Canon EOS R5 Mark II JPEG took a median 0.06 s over USB and 0.20 s over Wi-Fi; RAW files take longer in proportion to their size.

Where do my α7 III photos go?

Wherever you choose: Dropbox, Google Drive, OneDrive, SmugMug, ShootProof, an FTP/SFTP server and more — several at once — or just the phone. Gallery destinations such as SmugMug and ShootProof take the JPEGs; storage takes RAW too.

Does CloudTether offer live view or remote shutter for the α7 III?

Yes — new in CloudTether 1.1.x. Open the camera sheet for Live view or Remote: single shots, a timer, bursts or interval shooting, and each frame is delivered like any other. Set the camera's USB connection to PC Remote; hold to focus works. There's no exposure control, so set ISO, shutter speed and aperture on the α7 III.
