The Sennheiser EW 135P G4 Camera-Mount Wireless Cardioid Handheld Microphone System (516 to 558 MHz) features the proven combination of reliability, flexible control, and broadcast-quality sound that has made the EW Series an industry standard for videographers, journalists, and content creators all over the world. The EW 135P G4 gives you the tools to adapt and meet the wireless challenges that inevitably arise on set. The frequency scan function automatically searches for the cleanest frequency at your location, while the transmitter offers an interchangeable capsule design, allowing you to swap mic capsules with different polar patterns to suit your application. The system includes a camera-mount receiver and an updated, lightweight handheld transmitter equipped with an MMD 835 cardioid capsule ideal in situations where you don't have time to position a lavalier mic or you need to quickly pass the mic between several people. The receiver connects to a camcorder or a DSLR/mirrorless camera to capture crisp-sounding speech or dialog for projects ranging from wedding and corporate videos to red-carpet and man-on-the-street interviews in noisy environments.
