The SIGMA 105mm F2.8 DG DN MACRO | Art is a high-performance, mid-telephoto macro lens designed from the ground-up for mirrorless cameras. This impressive optic promises to offer superb image quality, fast AF and an impressive feature-set. It is equally well-suited to close-up macro work and a range of other photo and video applications including portraiture and weddings. The quality, functionality and versatility of this lens make it a valuable tool option for mirrorless photographers.
• Superb optical and AF performance typical of Sigma’s Art lens line-up
• Full range of functionality including aperture ring with de-click and lock options, and an AFL button
• Fast AF performance
• Excellent build quality with dust- and splash-proof construction
This all-new 105mm lens is first Art line macro lens designed specifically for mirrorless cameras brings to the table a range of advanced functionality including an aperture ring with de-click and lock functions, a customisable AFL button, dust- and splash-proof construction and a focus limiter switch. Its optical performance goes far beyond what one might expect of a mid-telephoto macro lens.
SIGMA prioritises optical performance above all else in its Art lens line-up, and it’s no different for the new 105mm F2.8 DG DN MACRO | Art. The lens gives an outstanding rendering performance from the centre of the frame all the way to the edges, and it minimises ghosting and flare very effectively, even in backlit conditions. The all-new optical design of the 105mm F2.8 DG DN MACRO | Art ensures exceptional sharpness at all shooting distances, from extreme close-up all the way to infinity. The lens produces clear, punchy results free of colour bleeding and with delicate rendering.
The lens’ sophisticated optical design means chromatic aberration is handled extremely effectively, and there has been a particular focus on longitudinal chromatic aberration, which cannot be easily dealt with by in-camera aberration correction. Sigma’s lens designers have worked hard to ensure the 105mm F2.8 DG DN MACRO | Art has exceptionally attractive bokeh, with beautiful bokeh circles, and smooth, natural-looking out-of-focus rendering in both the background and foreground. This is extremely important for both macro and portrait shooting.
The 105mm F2.8 DG DN MACRO | Art features a range of advanced functionality that open up a range of new shooting possibilities for both photographers and film makers. The lens has an aperture ring that allows users the option of controlling their aperture setting either via the camera or the lens. The dial can be de-clicked using a switch on the lens barrel, which allows film makers to tweak aperture during movie shooting without stepped changes to exposure, and this also allows quieter operation which can be very useful when shooting close-up subjects. An aperture ring lock button eliminates the risk of accidentally knocking the aperture ring from auto to manual or vice versa.
Also on the lens barrel is a focus limiter switch that allows users to limit the lens’ focusing range, resulting in faster overall AF performance. There are three settings: 0.295m-0.5m, 0.5m-infinity, or FULL. Adjacent to the Focus Limiter Switch is an AFL button, to which users can assign a particular function via the camera menu. This button sits in a convenient position to be controlled by the thumb and is useful for focusing control.
When equipped with the TC-1411 (1.4x) or TC-2011 (2.0x), SIGMA's latest teleconverters designed exclusively for use with L-Mount lenses, photographers can shoot macro at even higher magnifications while keeping the same working distance.
Typical of the exceptional build quality of Sigma’s Global Vision lens line-up, the 105mm F2.8 DG DN MACRO has a dust- and splash-proof structure which is built to handle a wide range of shooting conditions. The focus and aperture rings have a very smooth action and the switches are ergonomically designed and durable. With levels of user-friendliness, adaptability to the environment and smoothness of operation that are designed for professional use, the 105mm F2.8 DG DN MACRO | Art pushes the boundaries for photographers and gives them wider creative possibilities.
The lens is optimised for the latest face/eye detection AF and incorporates a powerful Hyper-Sonic Motor (HSM) in its focus motor system to achieve high-precision, quiet autofocus operation. All of these elements are brought to life using advanced production technology at the Aizu Factory, SIGMA's only production site, giving the 105mm F2.8 DG DN MACRO | Art the highest levels of performance.
