The K-S1 has the usual K-AF2 lens mount and supports nearly every Pentax lens ever made. As we mentioned earlier, the camera has sensor-shift IS, which offers 3.5 stops of shake reduction. The same mechanism that reduces shake can also be used for making small adjustments to composition, as well as Astro Tracing (with the optional GPS).

The 20MP APS-C CMOS sensor on the K-S1 is new to the Pentax lineup, and we'll see how it performs when we can start shooting with the camera.

Other items of note on the front of the camera include an AF-assist lamp as well as the receiver for an optional wireless remote control.
