Let's state from the beginning that there is a coated SMC version of this lens that should achieve better image quality. As this is an early zoom lens, I was not expecting to much, and my first photos seemed to confirm that sentiment. But, as I was using the lens during two shoots, it was starting to grow on me.
It's a smooth two-touch zoom lens that was pleasant to use. Easy to focus, easy to zoom. Worked well with the peak focus feature of the Sony a6000. The lens looked well used, but everything was still working as it was coming out of the factory. A testament to the quality build of these old Pentax lenses.
This lens is capable of reasonable sharpness across the whole image, especially when use at the outer edges of the range, and stopped down a few steps. Color is good, although some editing was required to make the colors pop. Even without SMC coating, the lens had little aberration, unless when used taking pictures in the direction of the sun.
So, nothing special, but for the low cost, it's not a bad lens. A good walk-around lens, with some occasional light macro work. A welcome addition to my Pentax collection that is still growing on me.
