Sigma’s 18-35mm f/1.8 DC HSM is part of their DC series of lenses designed for APS-C-sized sensors so the imaging circle is matched to the size of the sensor. For this assignment, I used a Canon EOS 60D with a 22.3x14.9mm sensor, producing an equivalent angle of view of a 28-56mm lens. Shooters of Nikon, Pentax, Sigma, and Sony cameras, the other mounts for which the lens is available, will achieve an angle of view equivalent to 27-52mm. Unlike other lens manufacturers, Sigma priced the different mounts the same ($799) so don’t feel you’re going to be paying a premium for your camera choice. Bucking a trend with camera manufacturers’ lenses, the Sigma 18-35mm f/1.8 DC HSM includes a lens hood at no extra charge.
When my fascination with macro began all my work was done by available light. Getting sharp images at life-size magnification took all the resolve I could muster, especially when dealing with heat and humidity or frigid conditions. It’s tough to hold a camera steady in those situations. What I wouldn’t have given for image stabilization!
The 70-200mm focal length has been the standard tele-zoom choice for many years, offering near normal to a good tele range that suits many practical purposes. Yet, quite a few stock-in-trade 70-200mm lenses had been slow or lost significant aperture as soon as you left the shortest zoom setting, making them a real challenge for handheld, low-light, or even max focal length shooting. Certainly, improvements in sensors and processors in terms of the high ISO/image quality ratio have helped. If you’re too slow on shutter speed with a variable aperture zoom you can always jack up the sensitivity. But that’s not always a great choice and it seems to force you to compromise image quality just to make up for the lens losing “speed” just when you need it most.
There are two types of fisheye: circular and diagonal. The Rokinon 8mm f/3.5 Aspherical Fisheye Lens is of the diagonal type, delivering a rectangular image with cropped-sensor lenses. The lens I worked with is designed for the Nikon DX (APS-C/cropped) sensor. The APS-C version provides a 180-degree field of view. Other versions are available for other “cropped-sensor” interchangeable-lens cameras, including Micro Four Thirds. My tests were conducted using the Nikon D300.
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 are a number of new lenses, including those for “full-frame,” Micro Four Thirds, and “mirrorless” compact system cameras debuting this year, listed in alphabetical order. Here’s a sampler, with a sprinkling of filters thrown in for good measure. We’ve shown prices when available at press time—if not, check the websites of the companies for updates.
Hoodman Custom Finder Kit
Hoodman’s Custom Finder Kit for up to 3.2” viewfinders includes a H32 HoodLoupe with German glass optics, a +/- 3 diopter adjustment, and a 1/4”-20 mount. Designed to fit all D-SLR cameras, the milled black anodized aluminum base plate is made in the U.S.A. (by Custom Brackets) and allows you to mount the HoodLoupe to your camera for video capture and live view. The base plate also features anti-twist bars, two 1/4”-20 tripod mount holes, a hand strap slot, and a camera sling strap attachment point. Hoodman’s Custom Finder Kit has a retail value of $199.99; the base plate may be purchased separately for $99.99.
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.

The Sigma 85mm f/1.4 EX DG HSM lens (average price: $969 on various Internet sites) is designed for full-frame cameras; with an APS-C multiply by your usual factor. At about 25 oz, I’d describe the lens as substantial, but not hefty. One of the reasons for the weight is the build—11 elements in eight groups, including the use of SLD glass, Sigma speak for Special Low Dispersion. The big chunk of glass on the end requires a 77mm filter. As to handling, Sigma has gone from their black “crinkle” finish to a smooth black rubberized finish that feels great to the touch. It’s plastic, not metal, but based on my experience with previous Sigma lenses, I’ve found them to be built to professional standards and can take a lot of abuse.
HDR Backdrop Series
Denny Manufacturing is now offering a new line of High Dynamic Range-looking backdrops. Created on the advice of a loyal customer, these backdrops are certain to save photographers precious time while adding a new dimension in contrast to their images. From Sports to Outdoor themes Denny has a backdrop to fit your needs and style.
Out of all the telephoto focal lengths, the 400mm is my favorite, so I looked forward to Canon’s updated 400mm f/2.8L. At about $11,499 list price (slightly less on searched street prices) it’s for those who absolutely need a fast, fixed focal length lens in their still and/or video work, and that’s work that pays well.
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.
