The image circle allows cinematographers to use not only on full frame sensors (Size = 43.14mm), but also able to fill the Vista Vision sensors on RED Monstro and the sensor on Arri Alexa LF (Size @ open-gate = 44.7mm) fully. The lens is also ideal for Super35-sized camera owners with the ultra-wide 17mm equivalent field of view and its future-proof decision when cinematographers need to upgrade to large format cameras. The optical distortion of ultra-wide angle lens will never be a nightmare for DoP. The distortion rate of good wide angle lenses in the market ranges from 2-4%. Venus Optics, however, are able to compress the distortion to a close-to-zero level. In fact, the ‘Zero-D’ claim had been validated by many existing Laowa lenses owners from all around the world.
