Recently, DSLR cameras have been evolving rapidly, & more & more photographers have been seeking a lens that can bring out the potential of a high-resolution sensor. There are occasions when photographers select zoom lenses as they offer more convenience than a fixed focal length lens, yet they do not want to compromise on image quality. SIGMA has long tackled this task to provide excellent quality images for such occasions. We are proud that SIGMA 24-105mm F4 DG OS HSM meets these requirements & is the standard zoom lens from our " Art" line, offering stable & fine image quality from wide to mid-telephoto range. It has a combination of fixed aperture & a good zoom ratio that we kept as high as possible. This lens incorporates the OS function & minimizes camera shake effectively. 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 a very handy zoom lens that covers the basic shooting range from wide to mid-telephoto. Moreover, its constant aperture of F4, OS (Optical Stabilizer) & HSM (Hyper Sonic Motor) enhances the lens usability. It is ideal for portraits, landscapes & general photography. Superior image quality This is a lens that represents the concept of our Art line, & 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 & color aberration. In order to compensate for these, various types of high-performance lenses, such as FLD, SLD & 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, & 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. * This lens cannot be used with film SLR cameras with the exception of the Nikon F6, Canon EOS-1v. * For Sony, OS function is not incorporated. Convenient handling The lens wide zoom ring ensures convenient handling. By putting the zoom ring in front, allows the lens barrel to be more compact. The inner focusing system eliminates front lens rotation, enhancing the lens stability & allowing use of Circular Polarizing filters.

SIGMA has a proven reputation for wide-angle lens design & manufacturing. Drawing on this experience & design know-how, refined through development of the SIGMA 35mm F1.4 DG HSM Art & SIGMA 50mm F1.4 DG HSM Art, we have successfully minimized sagittal coma flare, chromatic aberration, distortion & vignetting to achieve exceptional levels of optical performance with almost no aberration or distortion. This lens provides the best possible performance when photographing a variety of subjects from cityscapes, mountain ranges & the star-filled night sky that demands great rendering, to indoor photography with low illumination or scenes with a smooth bokeh effect. Enjoy the astonishing optical performance from the new "F1.4" series that has just joined the SIGMAs iconic Art line. Highest optical performance in its class. By minimizing aberration using the latest design technology & know-how that has been accumulated from lens development over many years, this lens achieves astonishing rendering performance, even in the corners, with ultra-high resolution. Whilst featuring higher resolution around the focus point, the lens ensures a smooth & natural bokeh effect. Both high definition rendering without color aberration & natural bokeh expression are possible, even from the maximum aperture. Excellent correction of sagittal coma flare Generally it is ideal for a lens to have a high rendering performance from the maximum aperture throughout the entire image. For instance, sagittal coma flare, where the point light sources do not gather at one point & leaves a tail, is a typical flare that occurs especially with wide-angle lenses. The SIGMA 24mm F1.4 DG HSM Art has an optimized power layout, positioning aspherical lens elements at the rear & adjusting the incidence angle of the light source, enabling high rendering performance even from the widest aperture. It is perfect for astronomical photography & shooting illuminations because of the reduced blur on the point light sources near the edge of the image. Excellent correction of chromatic aberration One of the elements required to achieve high rendering performance is the correction of chromatic aberration. Particularly, for axial chromatic aberration that is hard to correct even during image processing, the lens development stage was vital in ensuring minimized distortion. The SIGMA 24mm F1.4 DG HSM Art incorporates FLD ("F" Low Dispersion)* glass & SLD (Special Low Dispersion) glass elements to minimize chromatic aberration of magnification which is mainly visible around the edge of the image. Moreover the power layout ensures the correction of axial chromatic aberration. Without any color blur, it achieves high image quality throughout the entire focusing range, thus achieving sharp & high contrast image rendering. Minimized distortion It is not possible to compensate for distortion that is often observed with wide-angle lenses just by changing the aperture value. Therefore, the lens development stage was vital in ensuring minimized distortion. The SIGMA 24mm F1.4 DG HSM Art adjusted the incidence angle of the light source from the surface of the first lens & positioned each aspherical glass element to optimize the power layout at respective positions. This has helped it succeed in minimizing distortion throughout the entire image. Designed to minimize flare & ghosting Flare & ghosting were thoroughly measured & monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare & ghosting & provides sharp & high contrast images even in backlit conditions. Incorporating Rounded Diaphragm The 9 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image. Hyper Sonic Motor ensures High AF Speed The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. By optimizing the AF algorithm, smoother AF is achieved. It incorporates a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used. This allows the photographer to make focus adjustments quickly & easily. * Depending on the mount, initial operation of full-time manual focus differs ...
