This is Canon glass at its finest in the renowned L series category. The lens is in excellent condition, functioning perfectly. Glass elements have no damage and are clean. Electronic contacts in good shape, perfect communication with camera, tested on my 5D Mark IV at the time of this listing. The protective outer front ring has a small scratch (~1mm) that does not affect the filter thread. Retails new for ~$2000 Comes with original pouch and both covers, with an extra front cover and adhesive safety cord. This is what the official Canon website says about this glass: Canon's "L" series lens is its first mid-telephoto macro lens to include Canon's sophisticated Image Stabilization. With the highest quality optics available, combined with near-silent Ultrasonic focusing and life-size close-up capabilities without an adapter, the EF 100mm f/2.8L Macro IS USM is simply unrivalled. This is the full technical description by B&H expert photographer: Primarily designed for close-up shooting, the EF 100mm f/2.8L Macro IS USM from Canon is a versatile L-series short telephoto prime that is also well-suited for portraiture and other mid-range subjects. As a macro lens, however, this 100mm offers a life-size, 1:1 maximum magnification and an 11.8" minimum focusing distance. Complementing close-up shooting, an Image Stabilizer is featured that minimizes camera shake by two stops at full 1:1 magnification, or up to four stops at lower magnifications for sharper handheld shooting. Also contributing to smooth and intuitive handling, a ring-type USM and internal focusing design offers quick, quiet, and accurate autofocus performance along with full-time manual focus override. In regard to its optical assets, one ultra-low dispersion element is featured, to control color fringing and chromatic aberrations, and a Super Spectra coating has been applied to suppress flare and ghosting for improved contrast and color fidelity. Additionally, as an L-series lens, this 100mm f/2.8 is weather-sealed for working in inclement conditions. Short telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 160mm equivalent focal length. Ideal for macro shooting, this lens offers a life-size 1:1 maximum magnification along with a minimum focusing distance of 11.8" to suit working with close-up subjects. One ultra-low dispersion (UD) element greatly reduces chromatic aberrations and color fringing for improved clarity and color accuracy. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. An Optical Image Stabilizer helps to minimize the appearance of camera shake to better enable working in low-light conditions and with slower shutter speeds. The effectiveness of this system compensates for up to two stops of camera shake at 1:1 magnification, three stops at 1:2 magnification, and four stops at lower magnifications. A ring-type Ultrasonic Motor (USM), and internal focusing design, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. Focus Limiter switch lets you constrain the focusing to three different ranges for faster focusing performance: 11.8"-1.6', 1.6'-infinity, and the full 11.8"-infinity range. Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
