Sony Mic Records 32-Bit Float In-Camera

Sony has launched the ECM-W5, a professional wireless microphone system that sets a new benchmark with its groundbreaking in-camera 32-bit float recording capability. This advanced feature ensures exceptional audio headroom, preventing clipping in unpredictable sound environments. The system also offers an impressive maximum transmission range of 500m, delivering a rock-solid wireless connection even at extended distances.

Each transmitter for the ECM-W5 comes equipped with a generous 62.5GB of internal storage, effectively doubling the capacity found in many competing models. This allows for substantial onboard audio recording and serves as a crucial backup. The kit, including two transmitters and a receiver, is slated for release in November 2026 with a retail price of £350.

While the ECM-W5 is a premium offering, costing more than direct rivals like the DJI Mic 3, its unique features justify the investment for professionals. The ability to bake in 32-bit float audio directly into camera footage, combined with its extensive range and storage, positions it as a top-tier solution for videographers and content creators seeking the highest audio quality and reliability.
