and Exceptional Depth of Field
The Sony SAL 20mm f/2.8, a wide-angle autofocus lens featuring excellent accuracy and exceptional depth of field. It dispenses an ultra-wide 94° viewing angle, corrects visual irregularity from around 10 inches on to infinity, and dispenses extreme field depth for intricate photographs that preserve their crisp focus in close in foreground and far off backgrounds.
When mounted on a Sony Alpha DSLR camera body, this delightful wide-angle lens accomplishes a 70-degree viewing angle with a 30mm focal length similar to a 35mm SLR film camera.
Amazing Visual Preciseness: Advanced adjusting techniques to fix optical distortion and to create visually precise images with minimum aberration--allowing the foreground and the background to both be represented as they were actually viewed.
The lens features clear, sharp imaging: containing advanced optical coatings to inhibit internal reflection, achieving superb demarcation and clarity. There's deep field depth containing the aptitude to keep both the close foreground and the distant background in essential sharp focus.
The real lens elements move to increase AF speed and let you in on quick action shots. While conventional lenses close down their apertures using blades that can possibly create multi-sided forms, while the aperture blades inside this unique wide-angle lens create nearly a circle at the widest openings you'll employ for those poor-light shots, so those spotlight sources turn into a pleasurable circular defocused appearance.
The biggest down side is there's distance information for using the Sony flash system.
