Sigma 70mm F/2.8 Overview
Optimized for notable image clarity at close working distances, the Canon EF-mount 70mm f/2.8 DG Macro Art Lens from Sigma is a true 1:1, life-size macro lens well-suited for close-up and macro subjects. As a member of the esteemed Art series of lenses, this short-telephoto prime is also distinguished by its sophisticated optical design that makes use of two FLD elements, two SLD elements, one anomalous partial dispersion/high refractive index element, and two aspherical elements to limit both chromatic and spherical aberrations for high clarity, sharpness, and color accuracy. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Benefitting the imaging assets is a coreless DC motor that offers quick and accurate autofocus performance along with full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision.
- AS PART OF THE ART LINE WITHIN SIGMA’S GLOBAL VISION SERIES, THIS LENS IS DESIGNED TO ACHIEVE TRULY NOTABLE OPTICAL PERFORMANCE AND IS IDEALLY SUITED FOR CREATIVE AND ARTISTIC APPLICATIONS.
- SHORT-TELEPHOTO PRIME, THIS LENS IS DESIGNED FOR FULL-FRAME CANON EF-MOUNT DSLRS, HOWEVER CAN ALSO BE USED WITH APS-C MODELS WHERE IT PROVIDES A 112MM EQUIVALENT FOCAL LENGTH.
- TWO F LOW DISPERSION (FLD) ELEMENTS, TWO SPECIAL LOW DISPERSION (SLD) ELEMENTS, AND ONE ANOMALOUS PARTIAL DISPERSION/HIGH REFRACTIVE INDEX ELEMENT ARE FEATURED IN THE OPTICAL DESIGN, AND HELP TO REDUCE COLOR FRINGING AND CHROMATIC ABERRATIONS FOR IMPROVED CLARITY AND COLOR ACCURACY.
- TWO ASPHERICAL ELEMENTS ARE USED TO HELP LIMIT DISTORTION AND SPHERICAL ABERRATIONS AND ALSO CONTRIBUTE TO GREATER OVERALL SHARPNESS AND ACCURATE RENDERING.
- TRUE MACRO DESIGN AFFORDS A LIFE-SIZE 1:1 MAXIMUM MAGNIFICATION ALONG WITH A 10.2″ MINIMUM FOCUSING DISTANCE TO SUIT WORKING WITH CLOSE-UP SUBJECTS.
- A SUPER MULTI-LAYER COATING HAS BEEN APPLIED TO LENS ELEMENTS IN ORDER TO MINIMIZE LENS FLARE AND GHOSTING AND CONTRIBUTE TO PRODUCING CONTRAST-RICH AND COLOR-NEUTRAL IMAGERY, EVEN IN BACKLIT CONDITIONS.
- NINE-BLADE ROUNDED DIAPHRAGM CONTRIBUTES TO A SMOOTH AND PLEASING BOKEH QUALITY.
- CORELESS DC MOTOR IS USED FOR QUICK AND ACCURATE AUTOFOCUS PERFORMANCE. ADDITIONALLY, AN UPDATED FOCUSING ALGORITHM, FULL-TIME MANUAL FOCUS OVERRIDE, LARGE ANGLE OF ROTATION, AND FOCUS-BY-WIRE SYSTEM ENABLE INCREASED AND CONTROLLABLE FOCUS ADJUSTMENT.
- THE LENS IS CONSTRUCTED USING A THERMALLY STABLE COMPOSITE (TSC) MATERIAL, ALONG WITH TRADITIONAL METALS, FOR GREATER PRECISION AND USE IN WIDE TEMPERATURE VARIATIONS.
- THE BAYONET MOUNT IS CONSTRUCTED FROM BRASS FOR ENSURED ACCURACY AND DURABILITY. ADDITIONALLY, RUBBER SEALING IS INCORPORATED IN THE MOUNT DESIGN TO RENDER IT DUST- AND SPLASH-RESISTANT.
- COMPATIBLE WITH OPTIONAL EM-140 DG MACRO RING FLASH WHEN USED IN CONJUNCTION WITH THE SEPARATE 65MM MACRO FLASH ADAPTER FOR EVEN LIGHTING AS CLOSE WORKING DISTANCES.
- COMPATIBLE WITH OPTIONAL TC-1401 AND TC-2001 TELECONVERTERS TO EXTEND THE EFFECTIVE FOCAL LENGTH OF THE LENS WHILE RETAINING AUTOFOCUS FUNCTIONALITY.
- THIS LENS IS COMPATIBLE WITH THE OPTIONAL SIGMA USB DOCK FOR FINE-TUNING DIFFERENT LENS CHARACTERISTICS AND UPDATING ITS FIRMWARE.
