Canon 5D MII vs Pentax K-S1

In this write-up, we are looking at the Canon 5D MII versus Pentax K-S1, both Advanced DSLR digital cameras by competitors Canon and Pentax. The resolution of the 5D MII (21MP) and the K-S1 (20MP) is fairly well matched but the 5D MII (Full frame) and K-S1 (APS-C) use different sensor measurements.

The 5D MII was released 6 years before the K-S1 and that is quite a large difference as far as tech is concerned. Each of these cameras offer the identical body type (Mid-size SLR).

Before we go in to a in depth comparison, below is a brief highlight of how the 5D MII matches up against the K-S1 in terms of portability, imaging, features and an overall grade.

The following is a sample of the gallery pictures for Canon EOS 5D Mark II & Pentax K-S1. The complete galleries are available at Canon 5D MII Gallery & Pentax K-S1 Gallery.

For those who are intending to lug around your camera regularly, you have to think about its weight and size. The Canon 5D MII has external measurements of 152mm x 114mm x 75mm (6.0" x 4.5" x 3.0") along with a weight of 850 grams (1.87 lbs) while the Pentax K-S1 has specifications of 121mm x 93mm x 70mm (4.8" x 3.7" x 2.8") having a weight of 558 grams (1.23 lbs).

Keep in mind, the weight of an ILC will change depending on the lens you are employing at that time. Below is the front view measurements comparison of the 5D MII compared to the K-S1.

Looking at size and weight, the portability rating of the 5D MII and K-S1 is 56 and 69 respectively.

Generally, it is difficult to picture the difference between sensor measurements purely by checking a spec sheet. The graphic underneath will help offer you a much better sense of the sensor measurements in the 5D MII and K-S1.

Clearly, both the cameras enjoy different resolutions and different sensor measurements. The 5D MII because of its larger sensor is going to make getting bokeh simpler and the Canon 5D MII will give more detail as a result of its extra 1 Megapixels. Greater resolution will also make it easier to crop pics far more aggressively. The older 5D MII is going to be behind with regard to sensor tech.
