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 by default, but other reference sensors are selectable within the drop-down menu.
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. Default textual output is a crop factor and equivalent focal length, but this can also be changed to physical sensor dimensions and pixels.
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.
"Equivalent Focal Length" refers to the equivalent focal length that would mimic the angle of view of the current resolution setting if it were used on the chosen reference sensor.
