Sony SAL-20F28 20mm f/2.8 Wide Angle Reviews

Kurtmunger reviews the Sony SAL-20F28 20mm f/2.8 Wide Angle and writes;
“The Sony 20mm is very sharp in the centers at F/2.8, where the “DT” lenses, such as the kit lens, 18-200mm, and 18-250mm are soft from F/3.5-4. Distortion, light fall-off and color fringing are all about the same when the zoom lenses are set at 20mm.”

Features & Specifications

Sony SAL-20F28 20mm f/2.8 Wide Angle Specifications

It delivers a super-wide 94-degree 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-degree angle of view with 30mm focal length (35mm equivalent).


* 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 autofocus 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 spotlight sources have a pleasing circular defocused effect.
