Canon 5D vs Pentax K-3

Below, we will be evaluating the Canon 5D versus Pentax K-3, both Advanced DSLR digital cameras by companies Canon and Pentax. There is a large difference between the image resolutions of the 5D (13MP) and K-3 (24MP) and the 5D (Full frame) and K-3 (APS-C) possess totally different sensor measurements.

The 5D was released 9 years before the K-3 and that is quite a serious difference as far as tech is concerned. The two cameras come with the identical body type (Mid-size SLR).

Before going through a detailed comparison, below is a short synopsis of how the 5D grades versus the K-3 for portability, imaging, features and an overall rating.

Following is a preview of the gallery images for Canon EOS 5D & Pentax K-3. The complete galleries are available at Canon 5D Gallery & Pentax K-3 Gallery.

For anyone who is aiming to carry your camera often, you have to factor its weight and dimensions. The Canon 5D has outside dimensions of 152mm x 113mm x 75mm (6.0" x 4.4" x 3.0") with a weight of 895 grams (1.97 lbs) while the Pentax K-3 has dimensions of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") and a weight of 800 grams (1.76 lbs).

Remember, the weight of an ILC will vary based on the lens you choose at that moment. Here is the front view measurements comparison of the 5D compared to the K-3.

Taking into account size and weight, the portability rating of the 5D and K-3 is 55 and 59 respectively.

Generally, it can be tough to envision the gap between sensor sizing just by checking specs. The visual underneath should offer you a much better sense of the sensor sizes in the 5D and K-3.

All in all, both of the cameras have got different resolutions and different sensor sizing. The 5D featuring a bigger sensor will make achieving shallower DOF easier and the Pentax K-3 will give extra detail as a result of its extra 11 Megapixels. Higher resolution will let you crop photographs much more aggressively. The older 5D is going to be disadvantaged when it comes to sensor innovation.
