This is my favorite lens for the Mamiya 645 cameras. It is the perfect length for portraits. It lets you get a flattering perspective and tight composition without getting uncomfortably close to your subject (not many people like getting a camera jammed in their face). It also works very well for product photography. The lens is sharp and has excellent color quality. It also features a handy built-in hood. Note that this is the faster f3.5 version. The lens is in clean condition and works perfectly. The glass is clean and scratch-free and the mechanical action is smooth. Caps are included. This lens fits ALL of the Mamiya manual focus 645 cameras.
