Olympus OM-system Zuiko Auto-W 21mm F2 Ultra Wide-Angle Lens

The optical design of this iconic ZUIKO ultra-wide comprises11 elements in 9 groups. 

Its fast f/2.0 maximum aperture makes viewing and focusing much easier than with other slower speed lenses. 

It incorporates a floating element system for improved sharpness from its close 0.2 meter (0.7 ft) minimum focusing distance to infinity and to ensure its superlative optical performance is maintained over its entire working range. 

The use of special optical glass with a high refractive index corrects any possible aberrations such as spherical, curvature of field and also astigmatism to absolute minimal levels. 

The rear lens element is unusually large due to its extra light gathering power. 

The all-metal build quality is superb with an extended and slip-free diamond edged texture focusing grip for positive focusing action. 

Depth of field indicators are very well marked on the lens barrel along with a prominent infrared index provided for easy reference. 

Its top rated physical construction complements its widely acclaimed optical performance making this Zuiko classic such a desirable optic to own. 

This lens has always received rave reviews for its overall performance and never fails to live up to expectations.
