Note that firmware updates are required for the Pentax K-S1, K-S2, and K-3 for full compatibility and optimal focusing with this lens.  Older cameras will not fully support all of lens's focusing features.

As the Pentax full-frame DSLR is not due for release until late 2015, the tests that follow over the course of the following pages were performed with current APS-C bodies.
