About this model
The Sigma 105mm f/2.8 EX DG OS HSM Macro is a versatile prime lens for Nikon F-mount cameras. It offers true 1:1 macro magnification, letting you fill the frame with small subjects like insects, flowers or jewellery. The 105mm focal length provides a comfortable working distance and is also flattering for portraits. A fast f/2.8 maximum aperture delivers shallow depth of field and good low-light performance. Optical Stabilisation helps reduce camera shake, while the Hyper Sonic Motor (HSM) provides quick, quiet autofocus. As part of Sigma's EX line, it is built to a high standard and is a popular choice for macro enthusiasts.
