Canon APS-C Sensor (1.6×) vs. Medium Format 44×33 mm Sensor
Comparing 2 standards across 10 specifications. 10 key differences identified.
The Canon APS-C Sensor (measuring 22.2 × 14.8 mm with an active area of 328.6 mm² and a 26.68 mm diagonal) is Canon's proprietary sensor dimension, operating with a 1.62× (commonly rounded to 1.6×) crop factor relative to 35mm full frame. Used across all Canon EOS Rebel, EOS 7D/90D, EOS M, and EOS R-series APS-C bodies (R7, R10, R50), it is slightly smaller than the standard 1.5× APS-C format.
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).
