The FR-310 Hot Shoe Shotgun Microphone mounts onto your DSLR camera to pick up cleaner, more focused sound recordings. The FR-310 shuts out sound from the sides and back, with a pickup pattern that targets sound in front of the camera. Three gain settings pull in the right amount of sound in close-up or long shot situations, while a bass roll-off switch leaves low-frequency noise on the cutting-room floor. The integrated windscreen helps block wind noise, which aids in keeping your sound in the picture.
