Sony announced the ECM-W5 wireless microphone on Oct. 14. Sony's press release prices the two-transmitter kit at US $399.99, with availability in November 2026. The question for a US creator is whether it replaces a DJI Mic 3 or Rode Wireless PRO on a Sony body.
Prices and availability
- ECM-W5 kit (two transmitters, one receiver): US $399.99, per Sony. Sony's US product page showed it as a pre-order with estimated delivery Nov. 19 to 20.
- ECM-W5R receiver: US $189.99, per Sony.
- ECM-W5T transmitter: US $119.99 in the PR Newswire copy of the release. Alpha Universe's copy lists $189.99, the receiver's price. The two copies differ.
- Australia: Man of Many reports AUD $619 for the kit.
Prices are as of Oct. 14, 2026.
What Sony says it does
Sony says 32-bit float audio travels digitally through the Multi Interface (MI) Shoe to a compatible camera and records with the video in one file, with no separate audio file to sync. It also says 32-bit float works only at 48 kHz.
Sony also says each transmitter has 64 GB of built-in memory for backup, enough for up to 90 hours at 32-bit float and 48 kHz. It claims a line-of-sight range of up to 500 m and up to 11 hours of transmitter operating time.
Which cameras get the digital path
Sony's release says only "compatible" cameras and points to a compatibility page. That page showed "Coming Soon" and no cameras as of Oct. 14. Sony's press photo is captioned as the ECM-W5 on an Alpha 7R VI, which is not a compatibility list.
For everything else, Sony says the supplied USB-C adapter connects to smartphones and PCs that support USB Audio Class 2.0, and a transmitter can connect directly over Bluetooth. Its text names no path for older or non-Sony cameras.
Beside the DJI Mic 3 and Rode Wireless PRO
- ECM-W5: $399.99 per Sony. 32-bit float to the camera over the MI Shoe, 64 GB backup per transmitter, 500 m claimed.
- DJI Mic 3 (two transmitters, one receiver, charging case): USD $259 on DJI's US store, which showed "Out of Stock" beside the price. DJI lists 32 GB internal recording in 24-bit or 32-bit float and a range of up to 400 m.
- Rode Wireless PRO: $299 on Rode's US page. Rode lists 32-bit float on-board recording, 32 GB per transmitter and a range of up to 260 m.
Ranges are each maker's own claim, and none is a test result.
DJI's page says its Sony MI hot shoe adapter gives 48 kHz 24-bit digital audio with four-channel output. Only Sony claims 32-bit float to the camera. As of Oct. 14, Rode's page text describes no equivalent shoe path.
What the release does not settle
Camera support is open. Sony's compatibility page showed "Coming Soon" and no cameras as of Oct. 14. Sony's release describes 32-bit float reaching a camera only through the MI Shoe, so other routes are unaddressed.
Battery life and range are Sony's own figures, per Sony's release, and we have not tested them. On availability outside the US, Sony's release gives Canadian prices, and Man of Many reports an Australian one.
Why it matters
This is our opinion. We have not used any of these microphones.
If your Sony body is on the compatibility list once Sony publishes it, the ECM-W5 is the only one of the three whose maker describes a 32-bit float digital path into the video file. That is the whole case for paying $140.99 more than the DJI Mic 3 or $100.99 more than the Rode Wireless PRO.
If you shoot on another brand, or on a Sony body that is not listed, whether it replaces either rival is unconfirmed, since Sony's release names no path for those cameras. The backup recording is not a differentiator either: DJI and Rode both list 32-bit float internal recording. Wait for the camera list before pre-ordering.
