Canon has made a white paper available that details the new EOS-1D Mark IV camera. The Canon white papers are an interesting read and provide a lot of insight into the capabilities and operation of various digital SLR camera models.

Interestingly, the EOS-1D Mark IV does not have a full-frame sensor like the EOS-5D Mark II. Instead, the sensor has a cropping factor of 1.3. That’s an APS-H sensor, compared to the new EOS-7D‘s APS-C sensor with a nominal cropping factor of 1.6. Since the EOS-1D Mark IV features a very high burst rate, it will likely be used extensively for sports photography where a crop factor can assist in gaining some extra length out of a zoom lens.
