Optically, we can't find a whole lot to complain about with the Pentax 17-70mm ƒ/4. It's decently sharp even wide open; light falloff and distortion aren't much to be concerned about. Outside of the middle of the zoom range, the numbers for chromatic aberration are a little high for our taste: I'd assume that in order to keep costs down, Pentax opted not to include ED glass elements. However, the cost is already at the $600 level, which makes it sort of a loss-leader to the Pentax 16-50mm ƒ/2.8, which can be had for as little as $700, and offers pro-level performance at the cost of a little telephoto distance.
