Features:

Sony E 20mm f/2.8 Wide Angle Lens offers great features. Boasting on its optical quality, the three aspherical elements are incorporated in the lens layout to reduce astigmatism, coma, field curvature, and other monochromatic aberrations. This lens features a fast f/2.8 maximum aperture that permits operation in less-than-ideal lighting conditions and enables shooters to capture images with a shallow depth of field. Featuring a 20mm focal length, compact and lightweight design, and bright f/2.8 aperture, this wide-angle lens is ideal for a range of subjects, from landscapes to snapshots.

Feature Description

Flare and internal reflection

This rigrously corrected lens gives you a wide angle of view for images that benefit from dramatic perspective with minimum distortion. It's an ideal choice for covering spread-out scenes that you can't get far enough away from to cover with a "normal" lens. Meticulous attention has been paid to minimizing flare and internal reflection in this advanced design, with the result that excellent sharpness and contrast are maintained through the image.

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.

Rear focusing elements

Only the rear groups of the optical system move to focus the lens, which allows for speedy AF operation and a shorter minimum focusing distance. Since the front of the lens does not rotate, operability is improved when shooting with a polarizing filter attached.
