The O-VF1 47mm Viewfinder from Pentax is an auxiliary viewfinder for the Pentax Q camera that's ideal for framing an image in bright sunlight, when viewing on the LCD screen can sometimes be a challenge. The O-VF1 has an angle of view (49.5°) compatible with the 8.5mm (similar to 47mm in the 35mm format) standard prime lens for the Q camera. It mounts directly to the hotshoe of the camera for quick image and video composition.
