A wide-angle lens with uncommon accuracy and extraordinary depth of field. It delivers a super-wide 94° angle of view, corrects visual aberrations from about 10 inches to infinity, and provides deep depth of field for complex shots that maintain sharp focus in both close foreground and far background. Mounted on the Sony® α (alpha) DSLR-A100 camera, this beautiful wide-angle lens achieves a 70° angle of view with 30mm focal length (35mm equivalent). Key Features:
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.
