Panasonic S1R vs Pentax K-S1

Let's look more in depth at the Panasonic S1R and Pentax K-S1, former being a Pro Mirrorless while the latter is a Advanced DSLR by brands Panasonic and Pentax. There exists a large gap among the sensor resolutions of the S1R (47MP) and K-S1 (20MP) and the S1R (Full frame) and K-S1 (APS-C) provide different sensor sizes.

The S1R was revealed 4 years later than the K-S1 and that is a fairly serious difference as far as camera technology is concerned. The two cameras feature different body design with the Panasonic S1R being a SLR-style mirrorless camera and the Pentax K-S1 being a Mid-size SLR camera.

Before going into a in depth comparison, here is a quick highlight of how the S1R scores versus the K-S1 in the way of portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Panasonic Lumix DC-S1R & Pentax K-S1. The full galleries are viewable at Panasonic S1R Gallery & Pentax K-S1 Gallery.

For anybody who is going to carry your camera regularly, you will have to think about its weight and dimensions. The Panasonic S1R features physical measurements of 149mm x 110mm x 97mm (5.9" x 4.3" x 3.8") along with a weight of 1020 grams (2.25 lbs) while the Pentax K-S1 has dimensions of 121mm x 93mm x 70mm (4.8" x 3.7" x 2.8") accompanied by a weight of 558 grams (1.23 lbs).

Remember, the weight of an ILC will change depending on the lens you are employing at the time. The following is a front view size comparison of the S1R and the K-S1.

Using dimensions and weight, the portability grade of the S1R and K-S1 is 54 and 69 respectively.

Quite often, its hard to visualize the gap in sensor sizing just by looking through a spec sheet. The graphic below should offer you a better sense of the sensor measurements in the S1R and K-S1.

As you can see, both of the cameras come with different megapixels and different sensor sizing. The S1R using its bigger sensor is going to make shooting shallow depth of field simpler and the Panasonic S1R will result in extra detail because of its extra 27 Megapixels. Higher resolution will let you crop photographs a good deal more aggressively. The more modern S1R provides an advantage with regard to sensor innovation.
