The Pentax K-50 is, in its basic specifications, identical with the company’s new K-500 model. Both cameras offer a 16MP sensor, a built-in stabilizer system (based on sensor shift technology), all standard exposure modes of a modern SLR system and a very large and bright optical SLR viewfinder. The optical viewfinder offers a 100 percent field of view, which is a very uncommon feature in this SLR class. The only difference between the K-50 and the K-500 is the sealedbody of the K-50. This allows the user to work with the K-50 even under challenging conditions, such as heavy rain.

The Pentax K-S2 offers a more classical handling and design concept than its predecessor with a standard mode dial on the top and two setup dials for exposure parameters (one near the shutter release button, the second on the back of the camera). For menu navigation, it offers a standard control field, which uses four buttons to navigate or to select functions such as white balance, ISO speed, and shooting mode.

The Pentax K-S1 is a small but versatile DSLR system with a 20MP APS-C sensor. Its body design is based on a standard SLR concept, with a large grip on the right hand side and a pentaprism optical viewfinder. There are, however, some aspects of the camera that are quite unusual, mainly the use of LEDs to signal settings and functions. These LEDs sit on the front and back of the camera and can, for example, show how many people are included in the face detection function; indicate the choice of photo or video mode with a red or green circle of LEDs on the back; or, quite reasonably, indicate self-timer countdown via bright LEDs on the camera front.

The Phase One XF 100MP is a medium format camera with extremely high sensor resolution. It is a modular concept comprised of the Phase One XF camera body, which was introduced in the summer of 2015, and the brand-new IQ3 100MP digital back. The body has a 90-degree prism viewfinder and includes a Schneider-Kreuznach 80mm LS f/2.8 lens. As expected, this does not come cheap: the total price for this kit is $48,990 USD, as of this writing, and is the most expensive camera system we’ve ever tested.
