APS-C Sensor (1.5×) vs. 1.0-Type / 1-Inch Sensor (13.2×8.8 mm)
Comparing 2 standards across 9 specifications. 9 key differences identified.
The Standard APS-C Sensor (measuring 23.5 × 15.6 mm with an active area of 366.6 mm² and a 28.21 mm diagonal) operates with a 1.53× (commonly rounded to 1.5×) crop factor relative to 35mm full frame. Standardized across Sony E-mount (Alpha 6000 series), Nikon DX (Z50, D500), and Fujifilm X-mount systems, it is the most popular interchangeable-lens enthusiast format.
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.
