This versatile macro lens for mirrorless cameras offers the perfect blend of optical quality, features, style and portability
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. Available in E-mount and L-Mount, this impressive optic offers 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 must-own option for mirrorless photographers.
This all-new 105mm lens is first Art line macro lens designed specifically for mirrorless cameras, and 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.
Outstanding optical quality
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 is able to minimise 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 color 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.
Advanced on-lens controls for ease of shooting
The 105mm F2.8 DG DN MACRO | Art features a range of advanced functionality that opens up a range of new shooting possibilities for both photographers and film makers.
The lens has and AF/F switch (1) that toggles between automatic and manual focus. In manual focus, the focus ring has a very smooth action and using the SIGMA USB Dock (L-Mount only), the AF sensitivity can be customised. The focus throw is quite large by default to allow for precise manual adjustment when shooting macro subjects.
In a similar way to the 85mm F1.4 DG DN | Art and 35mm F1.2 DG HSM | Art, an aperture ring (6) 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 (4), 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 (5) 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 (3) 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* (2), 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.
*Limited to compatible cameras. Also, the functions depend on the camera.
