Old vs New Pentax Lenses: 1st of a series

The great thing about the Pentax K-Mount system is photographers have hundreds of lenses to choose from, ranging from half-century old film marvels to the latest and greatest digital gear. This is the start of a new series that will pit old lenses against new optics by taking them on photoshoots with the Pentax K-3 III Monochrome and a Sony a7rII full frame color digicam. Which lens wins? You decide!
