As Canon's first 85mm L-series lens with IS capability, it has an advanced optical formula with a large-diameter aspherical lens, plus a bright f/1.4 maximum aperture to deliver gorgeous, sharp and detailed images suitable for virtually any application. Its versatile combination of built-in image stabilization and its sophisticated design make it perfect for handheld use even in harsh environments. Ideal for portraiture and creating a natural sense of distance between the user and the subject with a variety of scenes and subjects, the EF 85mm f/1.4L IS USM is engineered to perform and deliver the results photographers desire. The EF 85mm f/1.4L IS USM marks a new level of agility in a medium-telephoto lens as Canon's first 85mm L-series lens to incorporate Image Stabilization. It delivers up to 4* stops (CIPA Standard) of stabilization, making handheld operation possible in a vastly increased number of scenarios from portraiture to snapshots and everywhere in between. The EF 85mm f/1.4L IS USM features a large f/1.4 maximum aperture, which produces a shallow depth of field for beautiful background blur, captures at a fast shutter speed, a bright viewfinder image as well as easy operation in low-light situations. Combined with its built-in IS, the EF 85mm f/1.4L IS USM helps capture images in a variety of environments where other lenses may require the use of a flash or alternate lighting source. For consistently sharp results, the EF 85mm f/1.4L IS USM features an Image Stabilizer system that provides significant shake reduction for up to 4* shutter speed steps. This helps provide reliable handheld performance and clear image detail in low-light situations or at lower ISOs. Because of Image Stabilization, the EF 85mm f/1.4L IS USM can also help minimize the need for a tripod. Built to L-series specifications, the EF 85mm f/1.4L IS USM not only offers optical excellence but is designed to perform in even the most challenging environments. It delivers a dust- and water-resistant construction with seals around the switch panel, the focus rings and the mount. The surface of the lens even features a smudge-resistant fluorine coating that repels water and oil and can easily be cleaned with a dry cloth.
