Micro Four Thirds Sensor vs. 1/1.3-Inch Mobile Sensor (9.6×7.2 mm)
Comparing 2 standards across 9 specifications. 9 key differences identified.
The Micro Four Thirds (MFT) Sensor (measuring 17.3 × 13.0 mm with an active area of 224.9 mm² and a 21.64 mm diagonal) is an open mirrorless standard established by Olympus and Panasonic, featuring an exact 2.0× crop factor and a native 4:3 aspect ratio. Equal to exactly half the diagonal of 35mm full frame, focal length calculations are simple integers (25mm = 50mm equivalent).
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.
