Canon 1D X vs Pentax 645Z

On this page, we will be matching up the Canon 1D X versus Pentax 645Z, both Pro DSLR digital cameras by companies Canon and Pentax. There is a substantial difference between the resolutions of the 1D X (18MP) and 645Z (51MP) and the 1D X (Full frame) and 645Z (Medium format) provide different sensor measurements.

The 1D X was unveiled 3 years before the 645Z which is quite a big difference as far as tech is concerned. Both of these cameras have the same body design (Large SLR).

Before diving straight to a full comparison, here is a brief synopsis of how the 1D X scores vs the 645Z in relation to portability, imaging, features and an overall mark.

This is a preview of the gallery images for Canon EOS-1D X & Pentax 645Z. The full galleries are provided at Canon 1D X Gallery & Pentax 645Z Gallery.

If you are planning to travel with your camera frequently, you will want to factor in its weight and volume. The Canon 1D X has got exterior measurements of 158mm x 164mm x 83mm (6.2" x 6.5" x 3.3") accompanied by a weight of 1340 grams (2.95 lbs) and the Pentax 645Z has sizing of 156mm x 117mm x 123mm (6.1" x 4.6" x 4.8") having a weight of 1550 grams (3.42 lbs).

Remember, the weight of an ILC will vary depending on the lens you have chosen at that time. Following is a front view proportions comparison of the 1D X compared to the 645Z.

Taking into account size and weight, the portability grade of the 1D X and 645Z is 50 and 49 respectively.

Often, it can be tough to visualize the gap between sensor dimensions just by going over specifications. The picture below will give you a far better sense of the sensor measurements in the 1D X and 645Z.

Plainly, both of the cameras have different megapixels and different sensor dimensions. The 1D X with its tinier sensor is going to make shooting shallower DOF more difficult and the Pentax 645Z will offer more detail having an extra 33 Megapixels. Higher resolution will make it easier to crop shots a bit more aggressively. The more aged 1D X is going to be disadvantaged with regard to sensor technology.
