Designed for camcorders with 1/3" image sensors and interchangeable lens mounts, the Letus 1/3" Pro Relay Lens can be mounted directly to the camera, letting you attach Letus 35mm adapters--such as the Extreme, Elite, or Ultimate--with minimal light loss. These adapters allow your camera to achieve reduced depth of field and thus more cinematic imagery. Compatible cameras for this lens include Panasonic's HPX-300 and JVC's HD series.
