Professional-Grade Brilliant Zoom Lens
Sony 24-70mm f/2.8 Vario-Sonnar T* Carl Zeiss Lens. A professional-grade
brilliant zoom lens specifically engineered for
Sony Alpha SLR cameras. It features a compact, lightweight layout and provides a wide-angle thru medium telephoto scope, which makes it perfect for a wide array of shooting situations.
Carl Zeiss' optical engineering along with anti-flare coatings are used to help in diminishing flare and for increasing contrast. When mounted on DSLR cameras with APS-C type sensors, the
35mm equivalent focal length becomes 36-105mm. The lens is an all-in-one compact, perfect for portraits, snapshots, interiors or outdoor scenes.
This excellent 24-70mm zoom is a versatile selection for a
wide array of photography applications...a go to lens, if you will, You'll always put it on and leave it on, delivering big-aperture brilliance that's easy enough to carry around.
It has a Sonic Wave Motor built for smooth,
quick and silent automatic focusing, the unique technology accomplishes high torque even at a low speed but quick response start and stop. The device is a piezoelectric device that quickly reshapes itself as voltage is applied.
These precision aspherical lens elements molded from glass handle distortion issues for more visually accurate and sharper images over the lenses entire zoom range.
It's big aperture operation which is similar to other big-aperture lenses layouts by Carl Zeiss, This particular 24-70mm lens is absolutely magnificent with its capability to acquire radiant high-resolution pictures in poor light situations requiring a wide open aperture.
Carl Zeiss pioneered this superb lenses coated optics which has T-Star coatings that virtually diminishes lens flare, internal reflections and scattering of light that can occur on air-to-glass surfaces.
Because light with different colors or wavelengths change direction at different angles as it slips through a lens,
Zeiss uses Extra-low Dispersion (ED) Glass to
get rid of chromatic aberrations
by fixing certain light wavelengths for sharper, clearer images with better defined colors.
A big reason its is a lightweight small package is the advantage of the Super SteadyShot image
stabilizer included every Sony system camera and allowing accessory lenses to dispense with the extra expense and bulk of lens
The lens includes 17 lens elements within 13 groups, of which 2 are aspherical lens elements and 2 are ED glass elements. A floating arrangement among the third to fourth lens element groups helps counterweigh any aberrations created by the lens zooming action.
Overall, it's one the better Carl Zeiss all around lens ever made.
A big downside to this 24-70mm lens is it's big size and heavy weight (2.11
pounds). This lens is neither small nor light enough to be a
walk around lens. Because of it's solid build and heavy body, I found that holding this lens becomes tiring for half day out shooting.
