About Sony 16-105mm

Product Information provided by the Manufacturer

DT 16-105mm F3.5-5.6 Wide-Range Zoom Lens

The 16-105mm rnage of this lens is a "sweet spot" for many photographers, wide enough at the 16mm end to capture indoor scenes and long enough at 105mm to fill the frame with relatively distant subjects. Comfortable handling is another plus, thanks to the compact and lightweight design.

Media

Circular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This 'bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

ED (Extra-low Dispersion) glass

As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, and provides superior contrast across the entire image, even at large aperture settings. Super ED glass provides enhanced compensation for chromatic aberration.

Aspherical lens elements

Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped "aspherical" elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight. Advanced Aspherical (AA) elements are an evolved variant, featuring an extremely high thickness ratio between the center and periphery. AA elements are exceedingly difficult to produce, relying on the most advanced molding technology to consistently and precisely achieve the required shape and surface accuracy, resulting in significantly improved image accuracy and quality.

Distance encoder

The distance encoder plays an integral part in ADI flash metering, which delivers high precision flash metering that is unaffected by the reflectance of subjects or backgrounds. The distance encoder is a lens component that directly detects the position of the focusing mechanism, and sends a signal to the CPU in order to measure distance to the subject. During flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.

Internal focusing

Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient if you're using a polarizing filter.

One lens, many possibilities - DT 16-105mm F3.5-5.6 Wide Range Zoom (SAL16105) 
 The 16-105mm range of this lens is a sweet spot for many photographers; wide enough to capture scenery and interiors and long enough to reach distant subjects. 

• High resolution and contrast throughout zoom range 
• Circular aperture for attractive defocusing 
• High performance ED glass and aspherical lens elements 
• Internal focusing for agile handling and response 
• 35mm equivalent focal length: 24-157.5mm 

Designed to take advantage of APS-size CCD imagers like the Exmor sensor of the Sony a (alpha) DSLR-A700 camera, this amazingly compact premium zoom lens provides superior all-around performance. Its 35mm-equivalent range of 24mm wide-angle to 157.5mm telephoto is perfect for capturing faraway subjects, sports events, dramatic landscapes and intimate close-ups. 

Smooth defocusing - Instead of a standard polygon-shaped lens aperture, this lens features a 7-blade circular aperture for more natural, rounded defocusing, or bokeh. 

Refined optical performance - Aspherical lens elements minimize distortion while ED (Extra-low Dispersion) glass elements provide superior contrast, resolution, and color fidelity. 

Fast, agile focusing - The internal focusing mechanism means the lens barrel doesn't move, enabling a more compact design, faster autofocus response, and reduced minimum focusing distances. 

Say goodbye to blur - Pair the lens with a camera by Sony featuring built-in SteadyShot image stabilization and you'll enjoy smooth, blur-free results when shooting handheld.
