A full-frame lens covering the most commonly used zoom range.
Offering F4 brightness throughout the zoom range, this lens covers a large variety of scenes, from wide-angle to medium telephoto.
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.

Rounded diaphragm
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.

Featuring a large 82mm filter size and high optical performance that maintains peripheral brightness.
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.

The finest in materials, usability and functionality.
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.

Excellent handling
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.
-
TSC (Thermally Stable Composite)
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.
(*)TSC (Thermally Stable Composite)
TSC (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. It has high affinity to metal parts which contributes to high quality product manufacturing. -
Flare and ghosting reduction
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.

MTF Chart
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.
*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.

Distortion
effective distortion
When you take a picture of a lattice pattern, it will appear as the blue dotted line shows. The red line illustrates how the lattice pattern will appear in the actual picture when any lens distortion is taken into account.
relative distortion
In this chart, the horizontal axis shows the ideal image height (the distance from the center to the edge of the image [mm]). The vertical axis shows the extent of distortion. The extent of distortion is represented by how much Y, which is the actual image height, grows (or shrinks) against Y0 which is the ideal image height.
When you take the picture of a square object, if the distortion amount shows a minus value, the image will be seen as expanded (Barrel distortion). If the distortion amount is a plus value, it will be seen as a recessed (Pincushion distortion). When the distortion value is close to 0, the appearance of distortion is very minimal.
Vignetting
The horizontal axis shows the image height (the distance from the center to the edge of the image [mm]).The vertical axis shows the amount of light in the image (based on the amount of light in the image center being 100%). If the peripheral amount of light is lower than the center, the four corners of image will be darker (vignetting).
