The Macro 150mm F2.8 EX DG HSM boasts Optical Stabilization (OS) critical to equipment sporting this focal range, and is now splash-proof. With a large aperture, this macro lens is ideal for shooting smaller things in our world that exist virtually unseen. This lens will focus on subjects close enough to render them "life-size". It provides extremely high optical performance from infinity to 1:1 Macro, and is also compatible with Sigma APO Tele Converters.
The SIGMA DG Lens Series are high-performance SLR lenses that offer full-frame sensor coverage designed to deliver the ultimate in performance on full-frame digital SLRs, Sigma DG lenses also bring out the best in 35mm SLR film cameras and APS-C size DSLRs. Remarkable image rendition is achieved by comprehensive correction of aberrations and distortions. Special care is taken to thoroughly minimize colour fringing caused by lateral chromatic aberration, which is particularly noticeable at high resolution in digital photography. DG lenses can offer both high contrast and subtle tonal gradations, unmarred by flare and ghosting, thanks to Sigma's digitally optimized optical design and original Super Multi-Layer Coating technology, which suppress reflections between image sensor and lens surfaces. Large image circles assure ample peripheral bright- ness to prevent vignetting.
The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. By optimizing the AF algorithm, smoother AF is achieved. Also, this lens offers full-time MF by rotating the focus ring of the lens while auto focusing. Without changing the AF/MF Focus Mode Switch, it allows faster focus adjustment.
The Sigma Optical Stabilization (OS) helps compensate for camera shake by reducing vibration in the DSLR camera system while taking a photograph. The OS offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.
The Technical Details:
Three SLD (Special Low Dispersion) glass elements provide optimum colour correction and sharpness throughout the entire range and Super Multi-layer coating reduces flare and ghosting. It has superior peripheral brightness and provides sharp and high contrast images even at maximum apertures. While 19 elements in 13 groups - minimum focusing distance 15” (38 cm) with maximum magnification ratio of 1:1 – the 9 blade rounded diaphragm creates an attractive blur to the out of focus areas of the image
