Estimate Crop Factors With RED Cameras

Use this tool to preview how a given focal length will appear depending on resolution setting and sensor type. Illustration depicts viewable area relative to a traditional 35 mm stills photography sensor.

The relative size difference between two sensors is typically expressed as a “crop factor.” A higher crop factor means a given lens will appear as if it were a longer focal length, and at the same subject magnification, that lens will also have more depth of field.

The crop factor of a RED Mysterium-X™ sensor is similar to the familiar Super 35 mm film format (with motion) and APS-H digital sensor (with stills). Then, as the resolution is decreased from the maximum setting, the crop factor increases. At 2K resolution, the Mysterium-X™ crop factor approaches Super 16 mm film.
