Sigma 150mm F2.8 EX DG OS HSM APO Macro: A “Full Frame” Tele-Macro
1 September 2003
Excerpt: The EX designation and matte texture give this glass a solid feel, but it is a bit hefty at over 40 oz. While the size, with lens shade attached, might garner some attention from passersby on the street, the lens did not feel awkward or unbalanced when attached to my Canon EOS 5D, especially after I removed the tripod collar. That step measurably reduced the weight and girth and made the lens more comfortable for handheld shooting.
Summary: Buy this lens if : - You want a high-performance macro lens that can also be used for portraiture for use on a 'full frame' body. - You want fast and quiet autofocusing. - You require built-in image stabilisation. - You require edge-to-edge sharpness for copying. - You want a lens that requires no readjustment when you fit filters.

Excerpt: This f2.8 lens is one of a number of Sigma macro lenses and sits between the 105mm and 180mm units. It is image stabilised and focuses internally so the lens barrel does not extend. It has full frame coverage and on an APS sensor camera has a focal length equivalent of 225mm. Construction and finish are outstanding, with a metal barrel and rubberised finish on the focusing ring. This ring is broad and the operation is super smooth with just the right damping.
