The 1D was launched 9 years prior to the K-x and that is a fairly big gap as far as camera tech is concerned. The two cameras feature different body design with the Canon 1D being a Large SLR camera and the Pentax K-x being a Compact SLR camera.

Before diving straight to a detailed comparison, here is a quick summary of how the 1D scores versus the K-x with regard to portability, imaging, features and an overall grade.

The following is a sample of the gallery pictures for Canon EOS-1D and Pentax K-x. The complete galleries are available at Canon 1D Gallery and Pentax K-x Gallery.
