The Sigma 105mm F2.8 DG DN Macro Art is a high-performance, mid-telephoto, macro lens designed for Sony full frame mirrorless cameras. With superb image quality, fast AF and many impressive features, this lens is equally well suited to close-up macro work and video applications.
Optical quality
This 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 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 Sigma 105mm offers exceptionally attractive bokeh, with beautiful bokeh circles, and smooth, natural-looking out-of-focus rendering in both the background and foreground.
1:1 macro
The lens’ 1:1 magnification ratio allows very close focusing so that the impression of the subject appears as life-size on the camera’s sensor. The minimum focusing distance is 29.5cm, giving a working distance of 14.1cm.
Advanced on-lens controls
The lens has and AF/F switch that toggles between automatic and manual focus. In manual focus, the focus ring has a very smooth action. The focus throw is quite large by default to allow for precise manual adjustment when shooting macro subjects. An aperture ring allows users the option of controlling their aperture setting either via the camera or the lens.
Perfect for portraits
As well as being a true macro lens with a 1:1 magnification ratio, the 105mm DG DN MACRO | Art can be used in a wide range of other shooting situations, for both photo and video. Its 105mm focal length is ideal for portraits, and it’s a perfect high-performing utility lens for weddings and events where the approach can be very varied. Optical performance is exceptional for both extreme close-ups to far-away objects, and AF is fast owing to the lens’ HSM focusing motor. The lens is optimised for modern mirrorless autofocus systems including auto-eye AF.
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 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.
Outstanding build quality
This lens 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.
