The EF200mm f/2L IS USM is a professional L-Series lens that incorporates the latest generation of Canon's high-performance Optical Image Stabilizer system (OIS), giving them a stabilization effect equivalent to a shutter speed four settings faster. In addition, they feature optical systems utilizing fluorite and UD lens elements to provide excellent chromatic aberration correction for high-resolution, high-contrast shooting performance. Both lenses use only lead-free glass, and also incorporate lightweight yet durable magnesium alloy lens barrels with enhanced resistance to moisture and dust.
The Canon EF200mm f/2L IS USM is an exceptionally sharp lens that is significantly lighter (2520g/5.5 lbs. vs. 3000g/6.6 lbs.) than its predecessor, the renowned EF200mm f/1.8L USM lens, while adding OIS and a weather-resistant design. Ideal for all kinds of low-light photography including portraiture as well as indoor sports, the EF200mm f/2L IS USM has a close-focus setting of 1.9 m/6.2 feet and a circular aperture system that enhances its background blur rendition at wide apertures.
