Pentax SMC 50mm f/1.2 K-Mount Lens A KA mount please read

all manual functions have been tested on a manual Pentax mount body, aperture and focus are both working fine, lens could do with a thorough cleaning, some sample images from adapting it to a Sony A7s are provided, the lens could be used as is with decent results I can't guarantee any of the A functions of this lens as I don't have a Electronic Pentax body available, due to this and the recommendation to clean the lens elements this has been listed as parts/not working

The Pentax SMC 50mm f/1.2 K-Mount Lens A KA mount would be the best fit for professional photographers in search of a high-quality prime lens for their K-mount camera system.
