The Sony ECM-B10 is an ultra-compact (79.3 mm long, 72 g) camera-mount shotgun microphone that uses four electret condenser capsules and digital beamforming signal processing to deliver three selectable directional pickup patterns with zero cables and zero batteries via Sony's Multi Interface (MI) Shoe.
4-capsule beamforming DSP and 3 switchable pickup patterns
Traditional shotgun microphones require a long acoustic interference tube to achieve narrow directivity. By combining four capsules with Sony's digital beamforming algorithm, the ECM-B10 achieves sharp off-axis sound rejection in a barrel just 79.3 mm (3.13 inches) long—staying completely out of view even with wide-angle vlogging lenses. A three-position rear switch lets you toggle instantly between Super-directional (tight front focus for solo vlogging and interviews), Uni-directional (wider front stage for small groups), and Omni-directional (360° environmental sound or operator commentary).
Direct Digital Audio via Sony Multi Interface (MI) Shoe
When mounted on a Sony Alpha or Cinema Line body with a Digital Audio Multi Interface Shoe (such as the α7 IV, α6700, ZV-E10, FX30, or FX3), the ECM-B10 converts sound to a digital signal inside the microphone body and transfers it directly to the camera without analog cable interference or camera preamp hiss. A DIGITAL / ANALOG switch on the back also ensures backward compatibility with earlier Sony MI Shoe cameras.
On-board DSP Noise Cut filter, tactile dials, and weather sealing
To minimize post-production audio cleanup, the rear panel includes a digital Noise Cut (NC) filter that suppresses steady air-conditioning or projector hum, a Low Cut (LC) filter that reduces wind and handling rumble, a 0dB / 10dB / 20dB attenuator switch for loud environments, and an AUDIO LEVEL dial with AUTO/MAN toggle. The shock-absorbing foot suppresses lens focus/zoom vibration, and the dust- and moisture-resistant body ships with a fur-type wind screen, connector protection cap, and carry pouch.
Bangladesh buying guide and camera compatibility check
Before ordering the Sony ECM-B10 from any seller in the BiponiBD catalog, confirm that your Sony camera has a Multi Interface (MI) Shoe and verify whether your body supports the Digital or Analog MI mode.
