Sigma has added yet another lens to its acclaimed range of Art optics and this time it’s the turn of the 105mm F2.8 DG DN Macro – a lens that will get you up close to a subject and offer impressive bokeh.

Available for E-mount and L-Mount full-frame mirrorless cameras and offering a number of features that will appeal to professional image makers, including an aperture ring that allows photographers the option of controlling their aperture setting either via the camera or the lens. What’s more, the dial can be de-clicked using a switch on the lens barrel, which allows those shooting video the ability to tweak aperture during movie shooting without stepped changes to exposure and with quieter operation.

Another feature to appear on the Sigma 105mm F2.8 DG DN Macro’s lens barrel is a Focus Limiter Switch that allows photographers to limit the lens’ focusing range (0.295m-0.5m, 0.5m-infinity, or FULL), and Sigma explains this results in faster overall AF performance. What’s more, when used with an APS-C sensor camera (such as the Sony a6600, the effective focal length increases to 157mm and this can be extended further by pairing the lens with Sigma’s 1.4x or 2x teleconverters.

The Sigma 105mm F2.8 DG DN Macro is built around a ‘17 elements in 12 groups’ design that includes one SLD element and Also features a 9-blade rounded diaphragm for pleasing bokeh. The front element of the lens features coating to repel water and oil and this in turn will improve image quality.

The lens is also resistant to moisture and dust, which will appeal to professional photographers looking to take this beast into harsh locations. When it comes to autofocus, the 105mm F2.8 DG DN Macro benefits from Sigma’s Hyper-Sonic Motor (HSM) technology for fast and quiet AF and Sigma also explains the optic is optimised for the latest face/eye detection AF.

Dimension-wise, the lens does well, tipping the scales at 715g and measuring 133.6mm in length. The Sigma 105mm F2.8 DG DN Macro also offers a decent closest focusing distance of 29.5cm.

Shipping with a lens hood and available from the end of October, the Sigma 105mm F2.8 DG DN Macro packs an impressively competitive price-tag, and will cost from £699.
