    Overview

    The Ricoh XR Rikenon 55mm f/2.2 is a cheap, easy-to-acquire vintage lens (PhotoSketchpad). Its main weakness is that it must be stopped down significantly to sharpen up, as commenters note it is not a 'good' lens wide open (PhotoSketchpad). Optically, it is a four-element, four-group design (PhotoSketchpad). Build and handling are not discussed in the excerpts. The lens suits photographers seeking an inexpensive, soft-focus effect for digital APS-C or full-frame, particularly those interested in modifying lenses for controlled spherical aberration (PhotoSketchpad).
