70mm F2.8 DG MACRO

Stunning resolution and clarity for a breathtaking visual experience - a razor-sharp macro lens joins the Art line

The long-awaited first macro lens in the Art line. The successor of the legendary, razor-sharp macro lens — the SIGMA MACRO 70mm F2.8 EX DG.

In recent years, macro lenses in the standard range have tended to employ inner focusing with the goal of maximizing autofocus speed. In contrast, the new SIGMA 70mm F2.8 DG MACRO | Art lens is designed to prioritize optical performance, fulfilling the demanding image quality requirements that define the Art line. In the standard to mid-telephoto range, it delivers stunning resolution and incredible clarity that greatly exceed expectations for a macro lens. The coreless DC motor further enhances image quality, while an optimized algorithm helps offer extremely smooth autofocus performance for a weightier, high-performance lens. Photography enthusiasts will recall a certain legendary, razor-sharp macro lens—the SIGMA MACRO 70mm F2.8 EX DG—and be glad to learn it is available in a new form, updated with outstanding Art line quality.

Design prioritizing optical performance
Top-level performance at every shooting distance

In order to realize top-level performance at every shooting distance, the lens features an extending, floating, two-group focus mechanism. This configuration minimizes aberration to produce optimal results at any focus distance. To minimize axial chromatic aberration, the optical system incorporates two FLD glass elements, two SLD glass elements, and one element with a high rate of anomalous partial dispersion and a high index of refraction. In addition, two aspherical lens elements help increase resolution at close shooting distances. This optical system makes possible a razor-sharp in-focus area contrasted with a bokeh area free of color streaking.

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Exclusive low-dispersion glass

The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.

Focus-by-wire system for comfortable and precise focusing

The focus-by-wire system eliminates the direct mechanical connection between the focus ring and the focus drive system. Controlled by SIGMA’s latest algorithm, a newly developed coreless DC motor adjusts focus with optimal speed and low noise. Full-time manual focus is available even during autofocus, allowing the photographer to make minute focus adjustments simply by turning the focus ring. In addition, the focus ring’s large angle of rotation helps the photographer achieve the extremely precise focusing required for effective macro photography.

Fast AF with full-time manual focus

Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

Note: The operation of full-time MF may vary based on mount type.

Mount with dust- and splash-proof construction

The lens mount incorporates rubber sealing※ to protect the mount from dust and water drops.

* Except for SIGMA mount

Rounded diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

High-precision, rugged brass bayonet mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

New SIGMA GLOBAL VISION product lines are setting new benchmarks for image quality
Evaluation with SIGMA’s own MTF measuring system: A1

We used to measure lens performance with a Modulation Transfer Function (MTF) measuring system using conventional sensors. However, we have developed our own proprietary MTF measuring system (A1)* using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. All SIGMA 70mm F2.8 DG MACRO | Art lenses are checked using this A1 system before they are shipped.

* A1:Aizu 1

46-megapixel Foveon direct image sensor

The 46 effective megapixel (4,800 × 3,200 × 3 layers) and 44 recording megapixel (4,704 × 3,136 × 3 layers) 23.5 × 15.7mm APS-C X3 direct image sensor captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46-megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.

Ultra-high precision and quality—all made in Japan

With only a few minor exceptions, all of SIGMA’s manufacturing, including molds and parts, takes place under a single integrated production system in Japan. We are now one of the very few manufacturers whose products are truly made in Japan. We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.

Stunning resolution and clarity for a breathtaking visual experience - a razor-sharp macro lens joins the Art line

In the news

In the field the biggest plus-points were the ability to take pictures in low-light conditions and the eye-catching nature of the close-range pictures that could be created…Unless something truly incredible is waiting around the corner, Sigma’s 18-35mm f/1.8 A-series lens will surely be the wide-angle zoom of the year for 2013′

‘The new Sigma 35mm f1.4 DG HSM Art lens has build quality and cosmetic finish designed to prime the highest expectations of optical performance. Although it’s modestly priced, every lens is destined to deliver peak performance. New electronics which can be reprogrammed through a USB interface which bayonets on to the mount, complete the package. Pixel for pixel it has higher resolution than any sensor type.’

‘In your hand, the quality of the award-winning Sigma 35mm f/1.4 Art is obvious – one of the early flag-bearers for Sigma’s new premium quality Global Vision range….It’s very sharp indeed, in fact sharper than rivals from Canon and Nikon.’

‘Lenses from the new ‘Art’ line in Sigma’s stable are intended to deliver premium quality in build, handling and imaging characteristics, along with high-level creative potential. This 35mm lens is exemplary in all these respects. It feels every inch a top-class professional lens, easing ahead of the Canon lenses in the group, which have a more run-of-the-mill, consumer-grade feel to them. Sharpness is outstanding, not only in the centre of the frame but right into the corners, even at very wide apertures… It’s more expensive than the other lenses tested, but a fabulous lens well worth the extra. Overall, it’s simply the best wide-angle lens in this group.’

‘Externally the standard of finish is impeccable. Like its newer, bigger brother, Sigma’s 50mm Art lens, the 35mm delivers superb sharpness and contrast even at its widest aperture. Especially impressive for a wide-angle optic, excellent sharpness is retained right into the corners of the frame when using wide apertures. Compared to the Samyang 35mm lens that’s on test, bokeh is rather smoother and more appealing.’

‘At £699 the Sigma 35mm f/1.4 DG HSM | A provides not only the joint-widest aperture in test, but also the best image quality. Tack sharp in the centre at its widest aperture, this lens offers the best balance of performance, features and price, and wins Best In Test.’

‘As for image quality, it rivals the Zeiss for correction – maybe even surpasses it; there’s practically no spherical aberration or purple fringing and it is sharp wide open. In fact, it’s so good that it’ll take something really special to beat it, but don’t hold your breath. Optical quality does cost a lot of money, but this is more accessibly priced than most and with AF it’s arguably the more practical option. Resolution and contrast is amazingly consistent, just what professionals demand in a lens like this.’

‘It’s all wrapped up in a contemporary and sleekly styled package, beautifully finished, with smooth and moderately weighted manual focussing. Sharpness is outstanding in the centre and well into the excellent zone at f/1.4, rising to a peak of almost 90{a85d0d947998bd8b1b3f988fbc98eccd45f806e38d75dfa20c8c560f6f1da76e} at f/2.8. Distortion is well controlled with 0.6{a85d0d947998bd8b1b3f988fbc98eccd45f806e38d75dfa20c8c560f6f1da76e} barrelling to rate Very Good to Excellent. CA is decently held in check, too, contributing to the exceptional standard of sharpness.’

‘At maximum aperture, images are sharp centrally with a high micro-contrast and resolution on our Canon full-frame test camera, with only a slight drop in sharpness at the borders.  Stopping down to f2.8 improves this at the edges but it’s a phenomenally impressive performance.  Flare and ghosting are low thanks to Sigma’s excellent digital optimised coatings. It’s sure to upset the big-name offerings that can’t match the performance wide open, even though they’re close to twice the asking price.’
