One of the kind! Amazing bokeh, extreme sharpness. Very special lens for portrait, flowers, and landscape. Works with Sony full-frame and APC-S sensor (becoming 157.5mm). "The Venus Optics Laowa 105mm f/2 (T3.2) is a manual-focus medium telephoto designed for great bokeh. It has superbly sharp optics. This all-metal lens has deliciously smooth backgrounds as well. It's an optical gem! ~ Ken Rockwell Mint, with original box and accessories.
