Crop Factor is a professional cinematography tool designed to simulate how lenses behave across different camera sensor formats. Built for cinematographers, camera operators, students, and filmmakers, the app provides an accurate and intuitive way to visualize lens crop factor and field of view across industry-standard cinema cameras. Modern productions often use multiple camera systems with varying sensor sizes. A lens will not behave the same way across different cameras, which can affect framing, composition, and shot consistency. Crop Factor solves this by allowing users to instantly compare how lenses perform on cameras from ARRI, RED, Sony, Blackmagic, and Canon, using professional lens sets from ARRI/Zeiss, Cooke, Leica, and DZOfilm.
