Panasonic S1 vs Pentax K100D

Let's look more closely at the Panasonic S1 and Pentax K100D, former being a Pro Mirrorless while the latter is a Entry-Level DSLR by competitors Panasonic and Pentax. There exists a noticeable gap between the resolutions of the S1 (24MP) and K100D (6MP) and the S1 (Full frame) and K100D (APS-C) boast totally different sensor measurements.

The S1 was brought out 12 years later than the K100D and that is quite a sizable difference as far as technology is concerned. Each of these cameras have different body design with the Panasonic S1 being a SLR-style mirrorless camera and the Pentax K100D being a Compact SLR camera.

Before we go into a more detailed comparison, here is a brief summation of how the S1 scores against the K100D in relation to portability, imaging, features and an overall rating.

Below is a preview of the gallery photos for Panasonic Lumix DC-S1 & Pentax K100D. The entire galleries are provided at Panasonic S1 Gallery & Pentax K100D Gallery.

If you're aiming to carry your camera often, you'll have to factor in its weight and proportions.

Do not forget, the weight of an ILC will differ dependant on the lens you are employing at that time. Underneath is a front view scale comparison of the S1 against the K100D.

Typically, it is hard to envision the difference between sensor sizing just by reading a spec sheet. The photograph underneath will give you a stronger sense of the sensor measurements in the S1 and K100D.

Clearly, both of these cameras provide different megapixel count and different sensor sizing. The S1 because of its bigger sensor will make getting bokeh less difficult and the Panasonic S1 will offer you greater detail having its extra 18MP. Higher resolution can also make it easier to crop photographs more aggressively. The newer S1 will have an advantage when it comes to sensor tech.
