The Dot Line NEX Adapter for Pentax M42 Screw Mount Lenses adapts Pentax M42 Screw Mount lenses to fit the NEX Mount on the Sony NEX Cameras. Since these cameras are mirror-less, this adapter will allow virtually limitless focusing. The NEX cameras retain the imaging qualities of an APS imaging sensor while being even smaller than a compact DSLR. Enjoy the ability to experience a NEX camera without having to buy another lens.
