Medium Format 44×33 mm Sensor vs. 1.0-Type / 1-Inch Sensor (13.2×8.8 mm)
Comparing 2 standards across 10 specifications. 10 key differences identified.
The 44×33 Medium Format Sensor (measuring 43.8 × 32.9 mm with an active surface area of ~1441 mm² and a 54.78 mm diagonal) provides approximately 1.67× the physical surface area of a 35mm full-frame sensor. Operating with a 0.79× 'reverse crop factor' and a native 4:3 aspect ratio, it is the digital medium format standard deployed in mirrorless systems by Fujifilm (GFX series) and Hasselblad (X system).
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.
