Sony SAL20F28 - 20mm f2.8 Wide-Angle A-Mount Lens Essentials Kit

Product Details:

Amazing Visual Accuracy - Advanced correcting techniques for optical distortion create visually accurate shots with minimum aberration so foreground and background are both represented as actually seen.

Clear, Sharp Imaging - With sophisticated optical coating to prevent internal reflection, this wide-angle lens achieves superb clarity and definition.

Deep Depth of Field - The ability to keep both close foreground and distant background in critically sharp focus.

Rear Focusing System - Lens elements at the rear of the lens move to increase auto-focus speed and help you catch quick action.

Circular Aperture - Conventional lenses close their apertures with blades that can create multi-sided shapes but the aperture blades of this superb wide-angle lens form a near circle at the wide openings you'll use for low-light shots, so spot-light sources have a pleasing circular defocused effect.
