Nikon vs. Canon: Competition for Pro DSLR Market Heats Up

Nikon Announces Five Pro Lenses

The two new zoom lenses are the wide AF-S Nikkor 14-24mm f/2.8G ED and the standard AF-S Nikkor 24-70mm f/2.8G ED. Both incorporate Extra-low Dispersion (ED) elements to minimize chromatic aberration, as well as aspherical elements for reducing other optical flaws. To achieve fast, quiet autofocus operation, they employ Nikon's Silent Wave motor.

The three new super-telephoto optics are the AF-S Nikkor 400mm f/2.8G ED VR, AF-S Nikkor 500mm f/4G ED VR, and AF-S Nikkor 600mm f/4G ED VR. The lenses have magnesium die-cast barrels to achieve a combination of light weight and durable, dust- and moisture-resistant construction. Each lens incorporates three ED elements, as well as a protective meniscus-type element that minimizes the ghosting caused by light reflecting between a camera's sensor and a typical flat protective glass element.
