18mm F3.5 Zen
"An ultra wide angle, super sharp, super performance lens with a 100 degree field of view.
At 100 Degree it covers an extended field of view even wider than a right angle. It is ideal for expanding your point of view and your photo horizons. Advanced integral focusing combined with a float element system minimizes aberrations for sharp, high contrast, high resolution photography through the entire shooting range- from 9.8” (25cm) extreme close-ups, to infinity. The sophisticated internal focusing mechanism allows this 18mm F3.5 lens to be extremely compact for maximum maneuverability. Whisper quiet and silky smooth, it uses a computer-aided designed optical formula for minimum distortion.
The unique Sigma Zen matte finish gives a sure, comfortable grip and helps prevent reflection while resisting scratches."
