Our verdict
The 105MM standard macro focal length is more suited to full-frame sensors, so producing a premium-positioned lens makes sense. For APS-C cameras, Sigma’s 70mm macro gives an effective 105mm or 112mm for Canon users and is therefore a better focal length.
The Sigma 105mm f/2.8 EX DG OS HSM Macro is an impressive lens that feels robust and handles well. The internal focusing is a welcome addition and, although the stabilisation has added weight and bulk to the lens, it is useful for handheld work at less than 1:1 magnification.
The quality of the optics has been improved to provide greater resolution and less vignetting than the previous model, bringing it to levels expected in this price range.
The problem is that Sigma may have created a space in the market for a budget macro lens.
Those searching for an affordable alternative around this focal length are now more likely to opt for the Tamron 90mm or Tokina 100mm than pay almost double for the extra features of Sigma’s new model.
