Full-Frame 35mm Sensor vs. 1/1.3-Inch Mobile Sensor (9.6×7.2 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 1/1.3-Inch Sensor format (measuring approximately 9.6 × 7.2 mm with an active area of ~69.1 mm² and a 12.0 mm diagonal) is the modern flagship smartphone camera sensor format. Operating with a ~3.6× crop factor and ultra-high pixel counts (50 MP to 200 MP with 4-in-1 / 16-in-1 pixel binning), it powers flagship mobile photography.
