SMC Pentax 67 105mm f2.4 lens mount_Mamiya 7 Internal dimensions are approximately 10x12x14cmThe legendary SMC Pentax 67 105mm f2. 4 is a medium format lens that lives up to the hype: thing looks good man. Excellent sharpness, distinctive bokeh, and just generally nice rendering all around. This lens is in excellent condition, with light wear from use and handling, including a few very small paint scuffs. Focusing is smooth, diaphragm is snappy, and optics are clean, with minor dust. A pretty swell lens.
