Canon EOS Digital SLR Camera Sensors
Canon are unique among digital SLR camera makers, in that they produce cameras with 3 different sizes of sensor: Most Canon EOS digital SLRs use a Standard APS-C size sensor but Canon Also produce DSLRs with a Full Frame sensor - the Canon EOS 5D and 1Ds series - and it makes the Canon EOS 1D series which use an APS-H size sensor, which is slightly bigger than standard. For reviews I concentrate on the two main sizes - Full Frame and the APS-C size which is the most common among digital SLR cameras from all manufacturers. Not sure which size sensor your camera has?
Unless you own a Canon EOS 1D, 1Ds or 5D series camera,
your Canon DSLR has the Standard, or APS-C size sensor.
