Full-Frame 35mm Sensor vs. 1.0-Type / 1-Inch Sensor (13.2×8.8 mm)
Comparing 2 standards across 10 specifications. 10 key differences identified.
The Full-Frame 35mm Sensor (measuring 36.0 × 24.0 mm with an active surface area of 864.0 mm² and a 43.27 mm diagonal) is the universal baseline benchmark in digital photography, defined with a 1.0× crop factor. Derived from the standard 35mm 135 still film format established by Oskar Barnack's Leica I in 1925, all focal length equivalents and field-of-view calculations are calibrated against it.
The 1.0-Type Sensor (commonly called a 1-Inch Sensor, measuring 13.2 × 8.8 mm with an active area of 116.2 mm² and a 15.86 mm diagonal) operates with a 2.72× crop factor and a native 3:2 aspect ratio. Originating from historical 1-inch vidicon video camera tubes, it is the benchmark format for premium compact cameras, creator vlogging cameras, and cinematic consumer drones.
