Product Description:

Deep, expressive bokeh

A large F1.8 maximum aperture makes it easy to achieve exquisitely expressive bokeh in deep, impressive images. 0.4-ft (0.12-metre) minimum focus and 0.2x maximum magnification2 let you shoot close-ups with wide, smoothly defocused backgrounds. Precisely controlled spherical aberration and a 7-blade circular aperture contribute significantly to the beautiful bokeh this lens can deliver.

High resolution throughout an ultra-wide 11-mm field of view

State-of-the-art optics deliver consistently high resolution right out to the image edges. Optimal placement of three aspherical elements ideally corrects field curvature, ensuring that excellent resolution is maintained throughout the image area, even at maximum aperture. Three ED (Extra-low Dispersion) glass elements effectively suppress chromatic aberration and colour fringing for superb image quality.

Compact and lightweight for extraordinary shooting freedom

The compact size and low weight of this fine lens make it a perfect match for APS-C camera bodies. Outstanding mobility and easy handling are great for long handheld or grip-mounted shooting sessions. An innovative combination of spherical and aspherical elements achieves stunning optical performance in a lens that is only 2.60 x 2.26 in (66 x 57.5 mm) and weighs only 6.4 oz (181 g) 

Advanced AF maximizes body speed potential

Two linear motors give this large-aperture lens impressively fast, precise auto focus and tracking performance for both stills and movies. AF and tracking are so responsive that the full speed potential of the body used can be fully realized so even fast or erratically moving subjects can be captured quietly and reliably.

A versatile tool for movie shooters

With an 11-mm angle of view and large F1.8 aperture, it is easy to capture dynamic subject perspectives against sweeping backgrounds with beautiful bokeh. Advanced optical design minimizes focus breathing3 and reduces unwanted angle-of-view shifts in movies. This unique ultra-wide lens also allows the use of front filters for extra creative flexibility in a wide range of shooting situations.

Superb operability and reliability

It may be small, but this impressive lens offers outstanding control and reliability. Linear Response MF provides instantaneous manual focusing with a natural feel, while a focus hold button and focus mode switch offer extra focusing control versatility. And to ensure maximum reliability in challenging outdoor conditions it features effective dust and moisture resistance4 throughout.
