The SEL-1018 provides 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.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.Three Spherical 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.The built-in Optical SteadyShot image stabilization system provides a 4-stop (approx.) shutter speed advantage, making it significantly to achieve crisp, blur-free images and video.Lens elements at the rear of the optical system move, allowing rapid auto-focus response.In low-light shots or nightscapes, out-of-focus light sources have a pleasing circular defocused effect.
