10-18 mm super wide-angle zoom lens
The SEL-1018 offers a constant maximum aperture of F4 through the entire focal length range, 
enabling use of the widest aperture at every focal length. Even in low-light environments, such 
as outdoors at sunset, users will be able to take advantage of the bright aperture and use fast 
shutter speeds without unnecessarily raising ISO sensitivity.
Minimum focal length of 10 mm (15 mm in 35 mm eq.)
Thanks to a minimum focal length of only 10 mm (15 mm in 35 mm-camera equivalency), the 
SEL-1018 delivers finely detailed, super wide-angle photos,  ideal for shooting majestic landscapes 
that can only be captured with super wide-angle lenses, as well as for producing striking photos 
with emphasized perspective.
Superb image capturing capability
Three Aspherical lens elements correct for spherical aberration and distortion, making it possible 
to shoot high-contrast, high-quality images with markedly less bleeding even at the maximum 
aperture. In addition, the optical system employs Super Extra-low Dispersion glass, realizing highly 
detailed images with reduced color aberration even at the 10 mm focal length. 
Built-in Optical SteadyShot™ image stabilization
The built-in Optical SteadyShot image stabilization system provides a 4-stop (approx.) shutter 
speed advantage, making it significantly easier to achieve crisp, blur-free images and video. 
Internal Focusing System
Lens elements at the rear of the optical system move, allowing rapid auto-focus response.
Circular Aperture
In low-light shots or nightscapes, out-of-focus light sources have a pleasing circular defocused 
effect.
