The Canon 100mm f2.8 Macro is a good quality macro lens that provides magnification up to 1:1 without the use of extension tubes. It’s also an excellent short telephoto lens in general, making it a good choice for portraits or other slightly-far-away subjects, though autofocus action is not as fast as most. Light cosmetic wear, good function. Note that this is a pre-USM lens, so motor action is decidedly not ultrasonic (it’s loud.)
