High-end fea­tures, bar­gain UK price

De­spite be­ing in­ex­pen­sive to buy (in the UK, at least), this Sigma lens is packed with high-end fea­tures. It has fast and quiet ring-type ul­tra­sonic aut­o­fo­cus, a dual-mode op­ti­cal sta­biliser with both static and pan­ning modes, and an aut­o­fo­cus range lim­iter that can lock out ei­ther the short or the long range. It’s sup­plied with a hood adap­tor for in­creased ef­fi­ciency in DX shoot­ing, and a padded soft case.

Op­ti­cal high­lights in­clude two SLD (Spe­cial Low Dis­per­sion) el­e­ments, sim­i­lar to Nikon’s ED glass, and Su­per Multi-Layer Coat­ings to re­duce ghost­ing. The aper­ture is well-rounded thanks to a nine-blade di­aphragm. For full 1.0x macro shoot­ing, the work­ing dis­tance be­tween the front of the lens and the sub­ject is 15cm, which is much more con­ve­nient than in the Nikon 40mm and 60mm lenses.

Per­for­mance

Per­for­mance is ex­cel­lent in all re­spects. Our only slight crit­i­cism is that sharp­ness could be bet­ter in the ex­treme cor­ners of the im­age frame. Even so, the Sigma pro­duces stun­ning macro images and is a joy to use.
