Sigma 70mm
Sigma 70mm F2.8 DG Macro Art for Canon - DSLR Camera Lens. The Sigma Art Lens features an extending, floating and a two-group focus mechanism to produce top-level performance which helps to reduce the aberration, in order to produce optimal results at any focus distance, it also include two FLD glass elements, two SLD glass elements and one element with a high rate of anomalous partial dispersion to effectively reduce axial chromatic aberration.
Design Prioritizing Optical Performance
Designed to Minimise Flare and Ghosting
Sigma has incorporated a Super Multi-Layer Coating in the 70mm f/2.8 DG Macro lens, that helps reduce the flare and ghosting when photographing images, even when shooting in backlit conditions. Photographers will appreciate this as it contributes to high quality and razor-sharp images.
Focus-by-wire System for Comfortable and Precise Focusing
Sigma has packed advanced features in the 70mm f/2.8 lens such as the focus-by-wire system that removes the direct mechanical connection between the focus ring and the focus drive system. A brand new coreless DC motor that allows you to adjust the focus with optimal speed and low noise has also been incorporated which is required for macro photography.
Fast Autofocus with Full-Time Manual Focus
The lens can easily be switched to manual focus by simply rotating the focus ring, all thanks to its full-time manual focus function.
Weather-Sealed Construction
The Sigma Macro 70mm f/2.8 Art lens features rubber sealing that helps protect the mount from dust and water drops.
Rounded Diaphragm
The Sigma lens features a rounded 9-blade diaphragm that creates attractive bokeh in the out-of-focus areas of the image.

High-precision, Rugged Brass Bayonet Mount
An exceptional durable lens is all thanks to its brass mount which combines high precision with a rugged construction.
Enjoy breath-taking and razor-sharp images with the all new mid-telephoto range Sigma Macro 70mm f/2.8 EX DG Art Lens, that's designed for full frame and APS-C Canon EF-Mount cameras and ready for 50+ megapixel sensors. A long-awaited macro lens has now arrived with impressive optical performance, whereas previous Sigma lenses has lacked this function of producing incredible clarity.
Improved specs and features include a large f/2.8 aperture to produce impressive bright images with attractive bokeh all thanks to its rounded 9-blade diaphragm, the coreless DC motor to produce enhanced image quality while an optimized algorithm helps deliver an extremely smooth autofocus, the optical system incorporates two FLD glass elements, two SLD glass elements and one element with a high rate of anomalous partial dispersion which all contributes to a better resolution when photographing up close subjects and minimised flare and ghosting even when shooting in backlit conditions.
- EF-Mount Lens/Full-Frame Format
- Aperture Range: f/2.8 to f/22
- Two FLD Elements, Two SLD Elements
- Low Dispersion and Aspherical Elements
- Super Multi-Layer Coating
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 colour 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.
Sigma 70mm
- 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 colour fringing and chromatic aberrations for improved clarity and colour 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 colour-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.
