The value and performance of this wide-angle lens soars to new heights. Whether you're shooting landscapes, group portraits, or travel shots, this lens was built to travel light. But it's no lightweight on quality. Tokina's AF 193 uses high-refraction, low-dispersion (HLD) all-glass optics made by Hoya Corporation and multi-coated with Tokina's exclusive anti-reflection coatings for outstanding optical performance in a value-priced lens.
