Nikon's latest DX-format lens offering is its most interesting and promising yet. Covering a 24-120mm full-frame-equivalent focal length, the lightweight 16-80mm f/2.8-4E features relatively fast apertures, an incredibly useful and dynamic focal length range (already proven with the popular full-frame 24-120mm f/4G ED VR), and professional treatments such as nano coating, an electromagnetic diaphragm, and even a fluorine coating on the front element.
While the electromagnetic diaphragm (a first for the DX format) helps give accurate and effective auto-exposure during high-speed exposure sequences (i.e. on "Continuous High" for action shots), full-fledged vibration reduction helps keep shots steady in the potentially shaky hands of any photographer.
The fluorine coat repels water, dirt, and oils on the front element (if you've seen this previous post, you'll understand why it should be on every lens) and is a happy trickle-down addition that I didn't expect would make it quite so soon to lenses for the mid-sized sensor format.
Finally, Nikon's "Nano Crystal Coat" is the first of its kind in a DX lens as well and comes from a heritage of providing world-class ghost and flare control on Nikon's most prestigious line of professional, full-frame lenses (for those without experience with such a lens, it's actually difficult to get lens flare even when pointed directly into the sun thanks to the nano coat).
What may at first sound like a hodge-podge of features turns out to be the recipe for what will likely and easily become Nikon's most versatile and impressive DX lens. While it won't come cheap, the 16-80mm f/2.8-4E ED VR is, in fact, a bit of a bargain at $1,066.95, considering it could easily replace three lenses in any kit.
