Ultra-wide F1.8 for stills and movies

With an 11mm (35mm full-frame equivalent: 16.5mm) focal length for dynamic images and a large F1.8 aperture for deep bokeh, this 181g (6.4oz.) APS-C format lens has the mobility you need to capture stunning stills and movies anywhere. It also features two linear motors for fast, precise AF that supports both stills and movies.

Deep, expressive bokeh

A large F1.8 max. aperture delivers expressive bokeh in deep, impressive images. 0.12 m (0.4 ft) minimum focus and 0.2x maximum magnification0 let you get close to the subject while producing beautifully defocused backgrounds. Precisely controlled spherical aberration and a seven-blade circular aperture contribute significantly to this lens' sensational bokeh.

Compact, lightweight freedom

This compact, lightweight lens is a perfect match for APS-C camera bodies, providing easy handling that is great for long handheld or grip-mounted shooting sessions. Spherical and aspherical elements combine to achieve stunning optical performance in a lens that is only 66 x 57.5mm (2-5/8 x 2-3/8in.) and weighs only 181g (6.4oz.)

Advanced AF maximises body speed potential

Two linear motors give this large-aperture lens impressively fast, precise autofocus 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 realised so that even fast or erratically moving subjects can be reliably captured.

Excellent ultra-wide resolution

Innovative optics deliver high resolution right out to the image edges. Optimal placement of three aspherical elements ideally corrects field curvature for excellent resolution throughout the image area. Three ED (Extra-low Dispersion) glass elements effectively suppress chromatic aberration and colour fringing for superb image quality.

Refined movies with minimal breathing

State-of-the-art lens technology packed into this remarkable large-aperture ultra-wide lens reduces unwanted focus breathing and angle of view shifts when focusing to facilitate high-quality movie recording and smooth, refined expression.0

Natural, linear manual focus response

For professional manual focusing feel and response, Linear Response MF ensures that the focus ring responds directly and linearly to subtle manual control. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise when shooting stills and movies.

A versatile tool for movie shooters

An 11mm field of view and large F1.8 aperture make it easy to shoot subjects against sweeping backgrounds with beautiful bokeh. That also makes this lens ideal for vlogging. Unlike many large-aperture ultra-wide designs, this unique design allows the use of front filters for extra creative flexibility in a wide range of shooting situations.

Consistent balance for easy handling

Thanks to a refined internal focus mechanism, the lens' length remains constant while focusing for ideal balance and handling. You can move in close to the subject, right down to the lens' minimum focusing distance, and shoot movies or stills without being restricted by changing lens length.

Easy manual/auto focus switching

The manual/auto focus mode switch enables instant switching between manual and auto focus modes, allowing instant response to changing shooting situations and focusing needs.

Customisable focus hold button

A customisable focus hold button is provided for easy access and convenient control. An alternative function can be assigned to the focus hold button from the body menus. You could assign the focus hold button to the focus magnifier function, for example, providing on-the-fly access to focus magnification while shooting.
