Olympus continues to push digital's optical envelope with the industry's widest non-fisheye lens for sub-full-frame DSLRs. A 14-28mm equivalent ($1,595, street), even by 35mm standards, this lens is extremely wide.
Its unusually large and double-sided aspheric elements, plus multiple elements of extra-low- and super-extra-low-dispersion glass (a total of three) help deliver performance unequalled in the ultrawide digital-only zoom category.
HANDS ON:
At 1 pound, 12 ounces, the lens is quite hefty by digital ultrawide and fixed-aperture standards. In comparison, fixed f/4 models from Nikon, Pentax, and Tokina, all 12-24mm, weigh only a pound (roughly). The Olympus is also more than an inch longer than these other lenses. However, it is internal-zooming -- the length doesn't grow as you zoom it out.
Other physical distinctions: a fixed lenshood, extremely smooth manual focusing, fast but slightly noisy AF, and protective gaskets and O-rings to repel dust and moisture. It does not accept threaded filters -- common with front elements as convex as this one.
