Expressive performance for high-resolution digital cameras. Introducing SIGMA’s new full-frame high-performance zoom lens.
Combining unprecedented image quality with zoom functionality, SIGMA proudly introduces this large-aperture high-resolution zoom lens.
Access the full power of your camera’s image sensor. This new zoom fulfills SIGMA’s uncompromising pursuit of high resolution.
The image sensors of digital SLR cameras continue to offer higher and higher resolution, and photographers are looking for high-performance lenses that leverage these sensors’ full power. In the case of zoom lenses as well, which are a dependable go-to in a wide variety of photographic conditions, photographers want convenience combined with exceptional optical performance. The new SIGMA 24-105mm F4 DG OS HSM zoom lens more than fulfills these requirements, offering exceptionally stable high resolution from wide-angle to medium telephoto photography.
While featuring a large-aperture 82mm filter size, this lens minimizes optical aberrations and avoids reduced peripheral brightness, an issue that tends to affect lenses with similar specifications. Each lens is checked with SIGMA’s proprietary A1 MTF (modulation transfer function) measuring system to ensure it offers exceptional quality for the high-megapixel era. Try this new high-performance zoom for yourself, and experience SIGMA’s uncompromising pursuit of high resolution.

When shooting of scenes in nature or travel destinations, photographers need a high zoom ratio combined with excellent handling to capture all the subjects they encounter. The SIGMA 24-105mm F4 DG OS HSM covers the most commonly used zoom range, from wide-angle to medium telephoto. It also takes usability to the next level, offering F4 brightness throughout the zoom range, OS (Optical Stabilizer) functionality, and HSM (Hyper Sonic Motor). Thanks to its convenient handling, the SIGMA 24-105mm F4 DG OS HSM is an ideal lens for many types of photography such as snapshots, portraits and landscapes.
* For Sony A-mount, OS function is not incorporated.
When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.
Offering exceptional expressive performance, this lens maintains peripheral brightness, which can be an issue with lenses in this class.
This high-performance lens joins SIGMA’s Art lineup, fulfilling its stringent requirements. Zoom lenses with a high zoom ratio tend to suffer from astigmatism, field curvature, distortion, chromatic aberration, and other optical aberrations. To minimize these, SIGMA’s zoom lens features optimally arranged high-performance single- and double-sided aspheric elements produced by precision glass molding and incorporating FLD (“F” Low Dispersion) glass and SLD (Special Low Dispersion) glass. Minimizing axial chromatic aberration at telephoto distances, this lens offers exceptional image quality throughout the zoom range. In addition, it avoids the reduced peripheral brightness that is common with lenses in the same class. Thanks to its large-aperture 82mm filter size, this lens offers truly outstanding optical performance.
A refined, integrated design made with the photographer in mind.
All lenses in SIGMA’s new Art line come with a hood with a high-quality rubberized connector and feature a newly designed lens cap and AF/MF switch, and are designed for intuitive use and superior functionality. Inside, HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing. Full-time manual focus override is another key feature that leaves the artistic touches in the photographer’s hands. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens. In both the external and internal parts, the optimized use of TSC (Thermally Stable Composite), an excellent match for metal parts, further contributes to the high-precision construction of the lens.

Positioning the zoom ring at the front of the lens helps make possible a slim barrel design. In addition, the wide, thick zoom ring contributes to the lens’s high usability. Thanks to SIGMA’s inner focus technologies, adjusting the focus and zoom rings does not change the length of the lens, resulting in excellent handling. Since the front of the lens does not move, the lens can be used with a circular polarizing filter.
A first for the industry, the barrel of the lens features a new TSC (Thermally Stable Composite) that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens. TSC also makes possible slimmer forms for parts like zoom rings and scaling rings.
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
