(From Sony lens literature)The new E 18-105mm F4 G power zoom lens is the first ever G lens created for Sony’s E-mount line of cameras. The premium all-around lens covers a generous 5.8x zoom range from 18mm – 105mm (full frame equivalent 27mm - 157.5mm) and is an ideal choice for travel photography as well as every day, general purpose shooting.
The innovative optical design of the new zoom reflects its G Lens pedigree. Two ED glass elements are combined with three aspherical elements for high resolution and contrast throughout the entire zoom range, minimizing distortion and color aberration.
Featuring a remarkably smooth, quiet autofocus and powerzoom operation, the premium G lens is particularly suited for video shooting. The conveniently-placed zoom lever on the lens barrel allows fixed or variable-speed power zooming, with easy fingertip operation to reduce unwanted camera shake. Further, the overall lens length remains unchanged during focusing and zoom operation, maintaining consistent handling and delivering a more natural shooting experience.
The E 18-105mm F4 G model has a circular aperture that enables smooth, professional quality background defocus, and maintains a constant F4 maximum aperture for plenty of brightness at all zoom settings. It also features Optical SteadyShot to cut the effects of camera shake while shooting.
