SIGMA 18-250mm F3.5-6.3 DC OS HSM for Pentax K

I AM SELLING MY OWN LENS. I HAVE USED RARELY BECAUSE I HAVE MANY MORE LENSES FOR PENTAX. Functionality: 7/10. Autofocus work WITH NOISE. All other function(manual focusing, image stabilization, zoom, aperture) work properly. Cosmeticaly: 9/10. Interior and exterior in very good condition: no dust, blemishes, scuffs or scratches. For some time I used only manual focusing and did not feel much discomfort. I have several lenses with a similar focal length, so I don't have time to do repairs. So I sell "as is". Maybe someone will like manual focusing or try to repair. Item pictured is the actual item for sale. Serial number is 1021685. The item includes: Lens, Front cover, Rear cover , Lens hood and original packaging.
