Sigma In Action
The proof is in the image! See how Sigma’s superior optics help these three photographers achieve their vision
Creating images that tell a story is perhaps the most central theme of Walter Arnold’s photography. While he shoots many different styles and uses a variety of techniques, Arnold tries to take pictures that allow the viewer’s imagination to go beyond just what a single frame shows. Using the Sigma 18-250mm F3.5-6.3 DC Macro OS HSM lens, he took this picture right outside his home. After two hours, the right moment came when this little green grasshopper hopped onto the tip of an unopened flower. Arnold got this shot less than a second before the bug jumped away. He says the versatility of the lens allows him to be prepared for just about anything when shooting.
“This is a fantastic all-around lens for any level of photographer. Having the ability to go from very wide at 18mm to zoomed way in at 250mm gives me a great amount of versatility,” Arnold says. “Combine that with the Optical Stabilization system, as well as the added bonus of having good macro capabilities, and you have a lens that covers a huge array of photographic needs and styles.”

To make this lens smaller and lighter, Sigma used a material called Thermally Stable Composite or TSC. It’s often compared to polycarbonate, as it has a high degree of elasticity, and expansion and contraction of the internal barrel is less prevalent in extreme temperatures. The material also reduces the size and weight. While Sigma’s non-macro 18-250mm is about 22 ounces, this version of the lens weighs about six ounces less. Besides having your macro to telephoto needs covered, the lens includes Optical Stabilization technology for capturing sharp images handheld and in low light.
Whenever Lindsay Adler shoots a portrait, she likes to add a bit of fashion flair. Clothing, hair, makeup and props are all elements that factor heavily into what she’s trying to accomplish behind the lens. For this shot, she and her client planned a variety of looks, ultimately deciding to go with an elegant dress and using a nearby sunflower field as the location, which influenced her lens choice.
To get the endless rows of sunflowers in the shot, Adler chose the Sigma 70-200mm F2.8 EX DG OS HSM. By using a longer focal length, she was able to compress her subject with the background, and the fast aperture gave her a narrow depth of field for putting the focus on her subject. “The 70-200mm F2.8 is fast, has a great bokeh, is incredibly sharp and focuses quickly,” she explains. “It is a fantastic portrait lens for close-ups and also when compressing the subject with the background.”
70-200mm F2.8 EX DG OS HSM
For capturing sharp shots at long focal lengths, the Sigma 70-200mm F2.8 EX DG OS HSM delivers top-notch image quality with the Optical Stabilization system holding your shot steady. More compact than its predecessor, the lens measures just 7.8 inches. FLD glass elements offset color aberration and Super Multi-Layer lens coating reduces flare ghosting over the entire zoom range.
Kevin Ames is constantly looking for photographs. The question he asks himself is how to make an image that’s been taken countless times
before look different. In his commercial work, his first priority is always to satisfy his client’s needs, and once he does that, Ames puts his own unique spin on the assignment. This was exactly his mind-set when he had some downtime during a workshop that he was helping John Paul Caponigro facilitate at Acadia National Park.
What looks like clouds in the background is actually the ocean. To get that effect in the early-morning light, Ames used a 30-second exposure to blur the water, and a flashlight to illuminate the foreground. He shot with the Sigma 24-70mm F2.8 IF EX DG HSM lens. “It’s wicked sharp – stunningly sharp and the autofocus is very responsive, making it great for low light. My eyes are older now so I appreciate that,” he jokes. “It’s also really compact and lightweight so it doesn’t take up much room. It’s just a good working lens, one of two that I always have with me.”

Fast focusing is crucial for getting wildlife or sports action shots where the scene often unfolds and changes very quickly. The Sigma 24-70mm F2.8 IF EX DG HSM has a Hyper-Sonic Motor that ensures quiet, high-speed autofocus, and a full-time manual override allows instant control in low-light situations. The lens is designed for full-frame DSLRs and weighs just 28 ounces.

Sigma Lens Technology
“F” Low Dispersion (FLD) glass
“F” Low Dispersion (FLD) glass has been adopted and used in Sigma’s new, high-performance lenses. FLD glass is the highest-level, low-dispersion glass available with extremely high light transmission. With a performance equal to fluorite glass, this optical glass has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics offer excellent correction for residual chromatic aberration (secondary spectrum), which cannot be corrected by ordinary optical glass, and ensure high-definition and high-contrast images. FLD glass offers superior optical performance, equal to fluorite, at an affordable price. The density of FLD glass is lower than traditional optical glass, ensuring a lighter construction of large-aperture lenses.
FLD glass has been incorporated into three recently announced lenses. Four elements have been included in the Sigma 8-16mm ƒ/4.5-5.6 DC HSM, and two elements have been included in both the Sigma APO 70-200mm ƒ/2.8 EX DG OS HSM and the Sigma 17-50mm ƒ/2.8 EX DC OS HSM.
APO (Apochromatic )
In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.
DC For Digital
These lenses are dedicated digital SLR camera lenses with an image circle designed to suit image sensors that correspond to APS-C size. In-house technology accumulated through the development of our digital SLR camera was used to optimize optical performance for our digital lenses. This is a high-performance lens series that fuses technology such as lens power layout and coating design with the know-how Sigma has built up over many years of developing interchangeable lenses for SLR cameras. By reducing the diameter of the image circle, Sigma has achieved a more compact, lightweight lens series.
DG For Digital
These are high-performance lenses optimized for digital cameras. They are ideal not only for 35mm digital SLR cameras and film SLR cameras but also for APS-C digital SLR cameras. They deliver superior image quality by correcting for all types of aberration, especially distortion, and they have high-resolution capability because they minimize chromatic aberration of magnification, which is particularly a problem for digital cameras. What’s more, these lenses incorporate optical designs optimized for digital cameras and Sigma’s own Super Multi-Layer Coating technology, so they reduce flare and ghosting due to reflection between the image sensor and lens surfaces, and they provide high contrast and a wide range of tone. They provide enough peripheral brightness with little vignetting.
With uncompromised design ideas and high-level optical technology and handling, these lenses, which are Sigma’s representative lenses, meet the requirements of photographers at the highest level.
HSM (Hyper-Sonic Motor)
These lenses are equipped with a motor driven by ultrasonic waves. The motor makes high AF speeds and quiet shooting a reality.
OS (Optical Stabilizer Function)
This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting by hand held camera.
