Sigma 24-105mm f/4 DG HSM ART - Sony A Fit

The Sigma 24-105mm F4 DG HSM is the perfect lens in this respect as it covers the basic shooting range from wide to mid-telephoto. Moreover, its constant aperture of F4, OS (Optical Stabiliser) and HSM (Hyper Sonic Motor) enhances the lens' usability. It is ideal for portraits, landscapes and general photography. This is a lens that represents the concept of Sigma's "Art" line, and it meets the highest standard of their quality tests. For those standard lenses with a high zoom ratio, they tend to show astigmatic aberration, field curvature, distortions and colour aberration. In order to compensate for these, various types of high-performance lenses, such as FLD, SLD and glass-moulded aspheric lenses including double-sided aspheric lens, have been included into the optical system. In addition, it suppresses chromatic aberration very effectively at telephoto-end, and achieves superior image quality throughout the zoom range. This lens overcomes low peripheral brightness that is common for those lenses with similar specifications. Also, the wide filter size 82mm is contributing for superior optical performance.
