Our Art line delivers high-level artistic quality
Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Designed
with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level
artistic expression. Developed with the maximum emphasis on artistic touch, they are designed to meet the
expectations of users who value a creative, dramatic outcome above compactness and multifunction. Along with
landscapes, portraits, still-life, close-up and casual snaps, they are perfect for the kind of photography that unleashes
the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture,
starry skies, underwater shots and many other scenes.
Covering the standard shooting range of 35mm full size image sensor
The convenience of a zoom lens enables photographers to capture various subjects without the need to change lenses.
The SIGMA 24-105mm F4 DG OS 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 Stabilizer) and HSM (Hyper Sonic Motor)
enhances the lens’ usability. It is ideal for portraits, landscapes and general photography.
Superior image quality
This is a lens that represents the concept of our “Art” line, and it meets the highest standard of our quality test. For
those standard lenses with a high zoom ratio, they tend to show astigmatic aberration, field curvature, distortions and
color aberration. In order to compensate for these, various types of high-performance lenses, such as FLD, SLD and
glass-molded 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.
Optical Stabilizer
This lens incorporates an OS system which offers superior stabilization, making it possible to compensate for camera
shake even in macro range photography where a small blur can be easily identified.
