Precise aspherical elements including two ultra-precise XA elements in an innovative G Master optical design work with two of Sony’s state-of-the-art XD Linear Motors to achieve extraordinary performance in a remarkably compact lens that weighs just 460 grams. Take this lens everywhere and reshape the world with creative new perspectives.
Two ED (Extra-low Dispersion) glass elements that are effective in correcting for chromatic aberration are combined with a Super ED glass element that provides even stronger chromatic compensation for excellent contrast and precise rendering throughout the image area.
With a 9-blade circular aperture mechanism and optimal application of two XA elements, this unique ultra-wide lens lets you emphasise subjects with dynamic close-up perspectives while creating beautiful bokeh in deep, expansive backgrounds.
The sun often ends up in difficult positions when shooting outdoors with an ultra-wide lens, sometimes causing unwanted flare and ghosting. Sony’s original Nano AR Coating II technology produces a uniform anti-reflection coating on lens surfaces, effectively subduing flare and ghosting in tricky lighting conditions.
Two XD (extreme dynamic) Linear Motors rapidly and precisely position this lens’s large, heavy focus groups for fast, accurate, quiet AF performance that maximises the speed potential of E-mount bodies. Quiet, low-vibration AF is a huge advantage when shooting movies, while compact mobility and fast response provide unrestrained creative freedom.
Linear Response MF ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, similar to the response of a mechanical focus system. Control is immediate and precise, so your creative intent is manifest without delay.
A variety of functions can be assigned to the lens’s focus hold button from the camera body interface to suit individual shooting preferences. You could assign the Focus Magnifier function, for example, allowing fingertip control of focus magnification for pinpoint manual focus.
An aperture ring that allows intuitive aperture control is provided, with click stops that can be switched on or off as needed. Turn the click stops on for tactile feedback that lets you “feel” the stops, or off when smooth, continuous, silent aperture control supported by the lens’s XD Linear Motors is required.
In addition to a fluorine coating on the front element that repels water, oil, and other contaminants, the rear element is also fluorine coated to keep that surface clean when changing the rear filter. A dust and moisture resistant design0 maximises reliability when using this large-aperture ultra-wide-angle lens in challenging outdoor conditions.
