This is a high quality standard macro lens for Pentax autofocus cameras. I also think that it is a perfect macro length lens on a APS-C camera. It is well built with superior image quality and would make an excellent addition to your kit.
This one is in excellent condition with minor wear. The autofocus on these are a bit loud, you may end up wanting to use the manual focus ring. The glass is clean and scratch free and the aperture is dry and snappy.
Caps are included.
