Compared to the Pentax K-x

The image above shows the K-r (left) next to the K-x. As you can see the visual differences are limited to the AF-assist light (underneath the mode dial), a boxier prism (presumably to accommodate the visible AF points) and more angular top plate, accompanied by a larger, higher resolution screen on the K-r. All other elements of the body design including the external buttons and dials are identical. The new prism means the K-r is about 5mm (3/16") taller than the K-x, but aside from that they're essentially the same size.

Despite its compact dimensions the the K-r feels solid in your hands, build quality is pretty much in line with the competition in this class. Like its peers in the entry-level sector it does not feature a top-LCD and comes with a relatively small number of external controls. The latter is made up for by an interactive status screen that is displayed on the rear-LCD (press the INFO button to enter) that gives you, in combination with the hard buttons, access to all of the important shooting settings. The K-r body is made out of reinforced ABS plastic, and the front including the grip is covered with a rubberized material.

New features and functions

The following table gives you on overview of the new features and functions on the Pentax K-r:

The K-r comes with a proprietary rechargeable battery as standard but gives you the option to use AA batteries (an optional battery holder is required). On the K-x you have to use AA batteries. At 921,000 dots resolution and 3.0 inch size (vs 2.7 inch/230K dots on the K-x) the K-r screen is, at least in terms of specification, identical to the K-5's.
The K-r viewfinder is the same size as the K-x but offers a visual confirmation of where the cameras has focused on (the active AF-point lights up in red). The K-r offers greater control over noise reduction. You can choose from five NR strengths and define different NR intensities for certain ISO ranges.
The K-r offers a new IR simple data transfer. This feature allows users to wirelessly transfer images between cameras.
The shooting menu includes the same new cross-processing option that we've seen on the K-5. It lets you choose from a range of parameters. There also two new custom image modes which we've seen on the K-5 - bleach bypass and reversal film. Custom image modes are also available when shooting movies.

The table below shows the specification differences between the Pentax K-r and K-x. The new model K-r is visually very close to the entry-level K-x but in some areas of the specification comes close to Pentax's enthusiast model K-5. Apart form the points already described above, the most noticeable differences are the increased sensitivity range up to ISO 25600 and the faster continuous shooting (6 fps vs 4.7).
