Overview

Photograph small objects in life-size form with the Sigma 105mm f/2.8 EX DG OS Macro Lens. You can use the lens for Sony A-mount cameras. The optical construction of the lens uses 16 elements in 11 groups that include a Special Low Dispersion and high refractive index SLD element to reduce various distortions and inconsistencies. Additionally, the Super Multi-Layer coating limits ghosting by improving light transmission. The focus-free mechanical construction ensures that the focus point remains pinned on the set area when holding the lens. You can use the focus limiter option to set a particular working range to attain a critical focus on the object. Sigma's proprietary Optical Stabilizer allows you to get stable, blur-free shots during handheld use. You can use a polarizer filter with this Sigma lens as it has a non-rotating front ring.

Elements / Groups: 16 / 11
Elements / Groups:
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
