The Sony UWP-D21 is a dependable camera-mount wireless lavalier microphone system that delivers uncompromising audio quality while still being easy to use and fast to set up with no menu diving. It is made with simplicity in mind for DIY cameramen, videographers, vloggers, and journalists working in the field without a crew. The system is packed with professional features including NFC Sync and Auto-Gain functions, which handle time-consuming frequency setup and mic-level adjustments for you, so you're ready to shoot within seconds.

The UWP-D21 offers digital signal processing for pristine audio and analog UHF transmission with true-diversity reception for reliability, even under difficult shooting conditions. Rugged and lightweight, this system includes a bodypack transmitter with an ECM-V1BMP omnidirectional lavalier mic. It also comes with a low-profile camera-mount receiver designed for enhanced mobility with compact camcorders and smaller DSLR/mirrorless cameras.

Sony shooters can take advantage of the SMAD-P5 digital MI Shoe adapter (available separately), which provides a direct, clean digital audio connection to select cameras equipped with a digital Multi Interface Shoe. With the UWP-D21, you can focus on the other critical elements competing for your attention during a shoot and confidently record crisp, clear speech or dialog for projects ranging from documentaries to wedding videos, YouTube content, corporate spots, and hands-free interviews.

The UWP-D21 is backward-compatible with Sony WL-800 and UWP Series systems.
