Canon 1D MIII vs Canon 1D X III

Let's look more in depth at the Canon 1D MIII versus Canon 1D X III, both Pro DSLR cameras and they are both created by Canon. There exists a noticeable gap among the image resolutions of the 1D MIII (10MP) and 1D X III (20MP) and the 1D MIII (APS-H) and 1D X III (Full frame) boast totally different sensor sizing.

The 1D MIII was announced 14 years before the 1D X III and that is a fairly sizable difference as far as camera technology is concerned. Both the cameras feature the same body design (Large SLR).

Before going into a in depth comparison, here is a short highlight of how the 1D MIII matches up against the 1D X III with respect to portability, imaging, features and an overall rating.

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

In case you're aiming to carry your camera regularly, you're going to have to factor in its weight and proportions. The Canon 1D MIII enjoys outside dimensions of 156mm x 157mm x 80mm (6.1" x 6.2" x 3.1") and a weight of 1335 grams (2.94 lbs) while the Canon 1D X III has measurements of 158mm x 168mm x 83mm (6.2" x 6.6" x 3.3") and a weight of 1440 grams (3.17 lbs).

Bear in mind, the weight of an ILC will vary based on the lens you are working with during that time. Underneath is a front view physical size comparison of the 1D MIII and the 1D X III.

Using dimensions and weight, the portability rating of the 1D MIII and 1D X III is 51 and 50 respectively.

Typically, its difficult to see the difference in sensor sizing just by checking out a spec sheet. The photograph here might give you a much better sense of the sensor dimensions in the 1D MIII and 1D X III.

Clearly, both of the cameras come with different megapixels and different sensor sizing. The 1D MIII using its smaller sensor will make shooting shallower DOF tougher and the Canon 1D X III will produce more detail with its extra 10 Megapixels. Greater resolution will also enable you to crop photos a good deal more aggressively. The older 1D MIII will be behind in sensor tech.
