Mount a Laowa EF-mount probe lens onto your R-mount Super 35/APS-C camera with this Laowa 0.7x Focal Reducer for Probe Lens from Venus Optics. This lens mount adapter widens the angle of view by 0.7x and adds one stop to the aperture. When used on a Super 35 camera, it lends the probe lens a 17mm focal length, and if used on a full-frame sensor, it is approximately the equivalent of 25mm. It is constructed with lightweight but durable aluminum and plastic materials.

Key Features

• Designed for mounting the EF-mount Laowa probe lens on a Super 35/APS-C R-mount camera body
• Manual adapter that maintains the image quality, which effectively eliminates the crop factor while making available to the sensor an additional one stop of light for each of the lens' f-stop settings
• The 0.7x Focal Reducer widens the angle of view by 0.7x, making the focal length of the probe lens 17mm, which is equivalent to around 25mm in full frame using a Super 35 cinema camera
• Enlarges aperture to f/10
• Aluminum and plastic components for durability and weight reduction
