Product description
The Sony SAL-16F28 16mm f/2.8 Fisheye Lens is a superb fisheye lens with a look all its own. This unique lens provides a fascinating perspective on landscapes, cities, crowds and special events. With a 180° angle of view and peculiar corner-to-corner sharpness, this lens achieves crisp, clear detail from about 8 inches to infinity. Mounted on a Sony α (alpha) DSLR camera, it provides a 110° angle of view with 24mm focal length (35mm equivalent). FEATURES: A Unique View of the World – With exaggerated perspective and intriguing visual distortion, this fisheye lens brings images closer to the focal plane for a view beyond the ability of human eye.4 Rotating Filters – Built-in filters may also be selected by simply rotating a dial on the lens–including Normal, 056 for accented Contrast in black-and-white photos, B12 to correct color by eliminating red tones, A12 to correct color by eliminating blue tones.

16mm F2.8 Fisheye Lens
Get creative with your photography the usage of the 16mm F2.8 Fisheye lens. This lens delivers expansive images that cover an extremely wide angle of view with curvilenear perspective. Along with eye-catching interpretations of reality, it offers extended depth of field to be able to capture huge vistas in which everything from 20cm to infinity is sharp, even at maximum aperture.
Technology
Circular Aperture
When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background may also 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 may also be obtained consequently.
ED (Extra-low Dispersion) glass
As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and consequently 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 all the 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 at the same time as 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 will 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 with a view to measure distance to the subject. Right through flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.
