Super wide angle zoom from 10 mm through 18 mm (15 mm to 27 mm in 35 mm full-frame format) with a constant F4 maximum aperture is ideal for expansive landscapes as well as emphasized perspective with any subject. Aspheric and ED glass elements contribute to spectacular resolution and contrast right out to the image edges even with the aperture wide open, while Optical SteadyShot image stabilization makes it easier to maximize the lens’s impressive performance potential in challenging low light situations.

* With interchangeable-lens digital cameras incorporating APS-C type image sensors.
When mounted on α series cameras with APS-C type sensors, the actual angle of view will be equal to the angle obtained at a focal length approx. 1.5 times longer than stated.
Less light is transmitted by any lens at the image periphery. If the light falloff becomes excessive, reduce the aperture by 1 or 2 stops.
