Essential Shotgun Mic for Sony Cameras
The Sony ECM-B1M is a compact, portable digital shotgun microphone designed for use with cameras equipped with the company’s MI (multi-interface) shoe. Thanks to its small, lightweight design, the ECM-B1M pairs perfectly with Sony’s Alpha series mirrorless cameras, forming a compact, balanced unit that’s ideal for run-and-gun and gimbal-mount shooting. Equipped with cutting-edge DSP and proprietary beamforming technology, the ECM-B1M employs eight mic capsules to capture natural sound, and then converts it to the digital domain and sends it to the camera via Sony’s MI smart shoe for cable- and battery-free operation. A digital/analog output switch is also onboard to support cameras with an analog audio interface. Ideal for videographers, podcasters, and content creators of all stripes, the ECM-B1M is a must-have accessory for any Sony Alpha shooter.

Three polar patterns, noise filters, and more
The ECM-B1M offers three selectable polar patterns (Super, Uni, and Omnidirectional), allowing you to tailor your audio pickup to the capture task at hand. Its vibration-resistant design suppresses structure-borne mechanical noise, while the intuitive rear-panel control set includes defeatable Noise Cut and Low Cut filters to ensure clean, high-quality audio. Other features include an Auto-Level circuit, dust- and moisture-sealed construction, and an included furry windscreen.


Sony: a trailblazer in digital audio and imaging
Founded in 1946, Sony boasts a distinguished legacy as a trailblazer in the world of electronics. Over the decades, Sony has been responsible for many significant advancements in consumer and pro audio and video. The Tokyo-based company’s pioneering efforts in digital imaging during the 1980s and partnership with renowned German lens maker Zeiss in 1995 resulted in groundbreaking products such as the widely popular Cyber-shot camera, released in 1996. However, it was the acquisition of Minolta’s camera division in 2006 that catapulted Sony to the forefront of professional digital photography and eventually cemented its status as an industry leader in mirrorless camera technology and optical lens design. Sony’s professional camcorders and video decks have long been industry standards in broadcast production, and the company leads the image sensor market with high-resolution sensors designed for industrial, automotive, mobile, and photographic applications, including those powering its high-performance cameras. Whether you’re a photographer, videographer, or multimedia creator, Sweetwater offers a Sony capture solution to match your needs.
