The Aires Coral 4.5cm f1.9 lens has a proprietory lens mount, and the focus, presumably is on the camera body since the lens does not have it. The aperture does not completely open at maximum. Perhaps that may have caused the strange looking, but still interesting bokeh. The lens is quite sharp, especially when stopped down. It has decentering problem, no doubt caused by my home made adapter. In all, an uncommon lens that produces interesting results. Thanks John!
