Coinciding with the announcement of the 5D Mark IV, Canon has introduced updates to two L-series lenses: the EF 16-35mm F2.8L III USM and EF 24-105mm F4L IS II USM. The 24-105mm F4L II offers improved image stabilization, claiming four stops to its predecessor's three, and adds air sphere coating for better resistance to ghosting and flare. Two aperture blades have been added, totaling 10 now - arguably one more than it should have for pleasing sunstar rendition.
The third iteration of Canon's 16-35mm F2.8L uses a large diameter GMO (glass-molded) dual surface aspherical lens. Like its predecessors the lens is water- and dust-resistant, and Canon claims the new lens boasts improved durability. We've seen some initial comparisons vs. the Mark II, and the Mark III clearly addresses one of its predecessors largest shortcomings - poor off-center performance - while arguably improving upon one of its most revered qualities: beautiful sunstars.
The EF 16-35mm F2.8L III USM will cost $2,199 and the EF 24-105mm F4L IS II USM will sell for $1099. Both lenses are scheduled for October availability.
