The sensor of your camera, by brand, and its crop factor.
Finds the sensor of your camera among the common photo and video cameras of each brand: its format, its size, its crop factor and its mount. Crop factor → opens that tool on this sensor.
Search by name (“fx3”, “gh7”) or pick a brand. The format comes from the manufacturers’ specs; the size shown is the common size of that format (each camera varies by a few tenths of a millimeter), except for a few cinema cameras whose exact size is given. Your camera isn’t listed? Pick the closest one, or type its size in Crop factor (Custom).
