Here's the whole scoop regards APS film formats vs the similar sized DSLR sensor formats. format: proportion - dimensions - diagonal ----- ------- ----------------------- APS-C: 2:3 - 16.7x25.1mm - 30.12mm APS-H: 9:16 - 16.7x30.2mm - 34.5mm APS-P: 1:3 - 9.5x30.2mm - 31.65mm FourThirds: 3:4 - 13.5x18mm - 22.5mm Canon "APS-C": 2:3 - 15x22.5mm - 27.04mm Nikon/Pentax/Minolta "APS-C": 2:3 - 15.7x23.5mm - 28.3mm APS-C film format is close but not the same as the "APS-C" sensor formats.
