The 1D MIII was announced 3 years prior to the 7D which is quite a significant gap as far as tech is concerned. Both of the cameras feature different body design with the Canon 1D MIII being a Large SLR camera and the Canon 7D being a Mid-size SLR camera.

Before delving into a in depth comparison, here is a short view of how the 1D MIII matches up versus the 7D in terms of portability, imaging, features and an overall mark.

The following is a sample of the gallery pics for Canon EOS-1D Mark III and Canon EOS 7D. The whole galleries are viewable at Canon 1D MIII Gallery and Canon 7D Gallery.

Oftentimes, it is tough to imagine the difference between sensor dimensions purely by reading through technical specs. The picture below will give you a clearer sense of the sensor sizing in the 1D MIII and 7D.

As you can tell, both of those cameras feature different resolutions and different sensor dimensions. The 1D MIII using its larger sensor is going to make achieving shallow DOF easier and the Canon 7D will resolve extra detail with its extra 8MP. Greater resolution can also help you crop pics way more aggressively. The more aged 1D MIII is going to be disadvantaged in sensor tech.
