Sigma’s popular tele-macro lens sees the addition of optical stabilisation and new lens coatings. Mat Gallagher discovers just how good this new version really is
Of course, for such a lens to be considered a true macro, it must reproduce its subject at life size (1:1) on the sensor, regardless of the sensor size.
Macro lenses come in various focal lengths, usually from 50mm upwards, but the focal length is important because, the shorter it is, the closer the subject must be to reach full 1:1 magnification. When you use shorter lenses, the subject can become shaded by the lens barrel and potentially be scared away if it is an animal. A longer macro focal length, such as the 150mm, is preferred by nature photographers as it allows them to keep some distance from their subject.
Sigma’s 150mm macro lens was first released in 2004. It is the longest of the four true macro lenses in the Sigma range, comprising a 50mm, 70mm and 105mm, all with f/2.8 apertures. This update is one of several that have been implemented to the range to add stabilisation and the latest glass coatings, both of which should improve the overall performance of the lens. However, with the original version of the 150mm macro often selling for less than £600, the initial selling price of £999.99 for the latest version may seem a little steep.
