Pentax K-1 vs Pentax K-5 IIs

Let's look a bit more in depth at the Pentax K-1 and Pentax K-5 IIs, both Advanced DSLR cameras and both are sold by Pentax. There is a sizable difference among the image resolutions of the K-1 (36MP) and K-5 IIs (16MP) and the K-1 (Full frame) and K-5 IIs (APS-C) feature totally different sensor size.

The K-1 was unveiled 2 years later than the K-5 IIs and that is a fairly significant difference as far as camera tech is concerned. Both of the cameras come with the identical body type (Mid-size SLR).

Before delving through a in-depth comparison, below is a brief synopsis of how the K-1 matches up against the K-5 IIs for portability, imaging, features and an overall rating.

Below is a preview of the gallery images for Pentax K-1 & Pentax K-5 IIs. The full galleries are provided at Pentax K-1 Gallery & Pentax K-5 IIs Gallery.

For anyone who is going to carry your camera often, you'll have to take into account its weight and measurements. The Pentax K-1 offers outer dimensions of 137mm x 110mm x 86mm (5.4" x 4.3" x 3.4") with a weight of 1010 grams (2.23 lbs) whilst the Pentax K-5 IIs has proportions of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") and a weight of 760 grams (1.68 lbs).

Remember, the weight of an ILC will change based on the lens you have at the time. Here is the front view measurement comparison of the K-1 and the K-5 IIs.

Factoring in size and weight, the portability rating of the K-1 and K-5 IIs is 55 and 60 respectively.

Oftentimes, it is hard to envision the difference in sensor sizing simply by looking through technical specs. The photograph below might give you a clearer sense of the sensor sizes in the K-1 and K-5 IIs.

As you have seen, both cameras posses different megapixel count and different sensor sizing. The K-1 using its bigger sensor will make getting shallower depth of field easier and the Pentax K-1 will render more detail having an extra 20 Megapixels. Higher resolution will make it easier to crop pictures somewhat more aggressively. The newer K-1 is going to have an edge in sensor tech.
