The New Benchmark For Wide Angle Zoom Lenses
Working in perfect harmony with high resolution sensors such as the one seen in the EOS 5D Mark IV, the high-performance lens provides expectional image quality for professional and serious enthuasiasts. The versatile focal length will appeal to wedding photographers and photojournalists who need to work up close, whilst the fast, constant f/2.8 maximum aperture makes it an obvious choice for those shooting in low light.
Constant F/2.8 Aperture
The fast f/2.8 aperture delivers impressive low light performance and depth-of-field control with no variation in shutter speed or ISO when zooming.
Sharp Images From The Center To The Periphery
Advanced optical design signnificantly improves disortion aberration, field curvature & stigmatism. 2 UD lenses reduce chromatic aberration of magnification.
Suppress Flaring And Chosting With SWC & ASC
Advanced lens coating; Subwavelenght structure (SWC) and Air Sphere Coating (ASC) guard against ghosting and flare to deliver superb image quality.
