FotodioX Pro Lens Mount Adapter for M42 Lens to Pentax K Mount Camera

This Pro Lens Adapter from Fotodiox enables the use of your M42 lenses on Pentax K mount SLR and DSLR cameras. It features a durable brass construction with stainless steel finish and ensures a dedicated tool is included with this M42 screw mount adapter to aid in removing and installing the adapter. Due to the focal flange distance of lenses and depth of the adapter, infinity focusing is not possible, making this adapter better suited for close focusing applications.
