Announced concurrently with the EOS 5D Mark IV are two new high performance L-series lenses; the EF 24-105mm f/4L IS II USM and EF 16-35mm f/2.8L III USM.

Canon’s popular EF 24-105mm f/4L lens has been upgraded, providing improvements to optical performance through new Air Sphere Coating (ASC), an anti-reflection technology that combines the existing vapour-deposited multi-layer coatings with an ultra-low refractive index outermost layer, which is in contact with the air where it significantly reduces flare and ghosting.  Fluorine coating has been added to the front and rear elements to prevent grease and dust from accumulating. The image stabilisation system has also been improved and now offers up to four stops of shake correction, while a new video design EDM provides quiet aperture adjustment and low-speed driving during movie capture. Details can be found at EF 24-105mm f/4L IS II USM.

The new EF 16-35mm f/2.8L III USM lens has been designed to complement high resolution sensors and provide outstanding image quality, particularly in low light levels, where its fast f/2.8 maximum aperture is advantageous. Its versatile 16-35mm focal length makes it ideal for wedding photographers and photojournalists who need to work up close. This lens also features Air Sphere Coating (ASC) as well as Subwavelength Structure Coating (SWC), which applies a different anti-reflective principle. Together they achieve excellent anti-reflective effects even  on surfaces with significant curvature,  as found in wide-angle lenses. These characteristics make this lens well suited to landscape photography. Visit  EF 16-35mm f/2/8 III USM for more information on this lens.

Both lenses feature dust and drip-proof construction and both are scheduled to go on sale from 8 September. Prices will be set at dealers’ discretion.
