While the Sigma 150mm f/2.8 lens has been out for a good while we decided to take a closer look at one of the most interesting pro-oriented products in their lineup. One of the key selling points in this lens is built-in optical image stabilization (“OS” in Sigma-speak) to aid in achieving camera-shake-free, handheld exposures. Granted, image stabilization in a macro lens is not the be-all and end-all of successful close-ups, though it sure gives added insurance. And because the Sigma 150mm OS macro is optimized for full-frame D-SLRs, it allows for use at the stated focal length with such cameras and provides even greater effective focal length with APS-C-type SLRs.

There’s something about a fixed focal length lens that brings the photographer out in me. It forces me to move in and back from compositions without resorting to a zoom. Yes, there are times when a zoom is most appreciated—especially the fast constant aperture zooms now available—but a prime puts me in a mindset that a zoom has yet to match.

The difference between a “constant” aperture zoom and other standard zooms is that when you increase the focal length on the standard zoom the maximum aperture narrows. This might make the difference between being able to hand hold or not when zooming in, and may indeed force the use of higher ISOs. Known as “fast” lenses, constant aperture zooms are pricier and bulkier than their variable-aperture counterparts. And to sweeten the pot, we’ve seen more and more fast lenses with built-in image stabilization, which gets you even more low light and steady shot capability.

The Sigma APO Macro 180mm F2.8 EX DG OS HSM lens boasts the company’s proprietary Optical Stabilizer (OS) technology and a wide f/2.8 aperture. The OS feature is said to allow the use of shutter speeds approximately four stops slower than would otherwise be possible, enabling handheld, close-up photography.

Every year the Technical Image Press Association (TIPA), a worldwide association of photo and imaging magazine editors, meets to pick the Best of Class in a wide range of photo categories. As the sole US member of the association, Shutterbug joins editors from Europe, Asia, and Africa in the nominating, judging, and selection process. One of the most exciting aspects of photography today is the constant advancement of technology and design, and this year’s Top Products reflect that spirit and those accomplishments, including new categories of Video D-SLR and Mobile App. Editor George Schaub joins all fellow TIPA members in congratulating those selected to receive the prestigious TIPA award.

Every year manufacturers and distributors unveil new products at trade show events. They see these shows as the best venues to garner the attention of the gathered members of their industries and to show them their latest wares. In the photo industry this has traditionally been the annual Photo Marketing Association (PMA) Show, which we have always covered. This year that event was subsumed into the larger Consumer Electronics Show (CES) in Las Vegas.
