Canon 5D MII vs Pentax K-3 II

On this page, we will be analyzing the Canon 5D MII and Pentax K-3 II, both Advanced DSLR digital cameras by companies Canon and Pentax. The sensor resolution of the 5D MII (21MP) and the K-3 II (24MP) is relatively well matched but the 5D MII (Full frame) and K-3 II (APS-C) posses totally different sensor measurements.

The 5D MII was manufactured 7 years prior to the K-3 II which is quite a sizable difference as far as tech is concerned. The two cameras have the same body design (Mid-size SLR).

Before getting right into a comprehensive comparison, here is a short introduction of how the 5D MII scores versus the K-3 II in terms of portability, imaging, features and an overall score.

Here is a preview of the gallery photos for Canon EOS 5D Mark II & Pentax K-3 II. The entire galleries are available at Canon 5D MII Gallery & Pentax K-3 II Gallery.

In case you're planning to carry around your camera often, you will have to consider its weight and dimensions. The Canon 5D MII enjoys exterior dimensions of 152mm x 114mm x 75mm (6.0" x 4.5" x 3.0") having a weight of 850 grams (1.87 lbs) and the Pentax K-3 II has dimensions of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") along with a weight of 800 grams (1.76 lbs).

Keep in mind, the weight of an ILC will change based on the lens you use at that time. Below is a front view physical size comparison of the 5D MII and the K-3 II.

Looking at size and weight, the portability score of the 5D MII and K-3 II is 56 and 59 respectively.

Generally, its difficult to visualise the difference between sensor sizes simply by looking at specifications. The pic underneath will help provide you a stronger sense of the sensor dimensions in the 5D MII and K-3 II.

To sum up, the 2 cameras have different resolutions and different sensor sizes. The 5D MII because of its bigger sensor will make achieving bokeh less difficult and the Pentax K-3 II will resolve more detail due to its extra 3MP. Higher resolution will also allow you to crop photographs a bit more aggressively. The more aged 5D MII is going to be disadvantaged in sensor innovation.
