This Pro Lens Adapter from Fotodiox enables the use of your Konica AR lenses on Pentax K mount SLR and DSLR cameras. It features a durable brass construction with stainless steel finish and a leaf spring ensures a secure connection between the lens and adapter. Additionally, through the use of a 1.4x multi-coated focus correction lens, this adapter is designed to maintain infinity focus. This correction lens can also be removed to render the adapter as an extension tube for macro shooting.
