As part of the EOS VR System – this lens paired with the EOS R5 updated with firmware 1.5.0 or higher and one of Canon’s VR software solutions – you can create immersive 3D that can be experienced when viewed on compatible head mount displays including the Oculus Quest 2 and more. Viewers will be able to take in the scene with a vivid, wide field of view by simply moving their head. This is the world’s first digital interchangeable lens that can capture stereoscopic 3D 180° VR imagery to a single image sensor.
The pairing of this lens and the EOS R5 camera brings high resolution video recording at up to 8K DCI 30p and 4K DCI 60p.
