Macro Sigma Art Sigma 70 mm f / 2.8 DG lens for Canon EF

Optimized for remarkable image clarity at close working distances, the Canon macro art lens EF-mount 70mm f / 2.8 DG from Sigma is a true 1: 1, life-size macro lens, ideal for close-ups and macro subjects . As a member of the esteemed Art lens series, this short telephoto lens is also distinguished by its sophisticated optical design that makes use of two FLD elements, two SLD elements, a high refractive index / anomalous partial dispersion element and two aspherical elements. to limit chromatic and spherical aberrations for clarity, clarity and color accuracy. The super multilayer coating also improves the quality of the image by suppressing the lens reflection and the ghost image to improve contrast and color fidelity under bright lighting conditions. In addition, a rounded nine-leaf diaphragm contributes to a pleasing bokeh quality.

The benefit of the image assets is a coreless DC motor that offers fast and accurate autofocusing performance along with full-time manual focus override. The physical design uses thermally stable composite material for durability in a wide range of environments, and a bayonet bronze mount also offers rigidity and mounting precision.
As part of the Art line within the Sigma Global Vision series, this lens is designed to achieve truly remarkable optical performance and is ideal for creative and artistic applications.
This short telephoto lens, this lens is designed for EF Canon full-frame digital SLRs, however, it can also be used with APS-C models in which it provides an equivalent focal length of 112mm.
Two elements of low dispersion F (FLD), two elements of low special dispersion (SLD) and an element of index of refraction / anomalous partial dispersion are presented in the optical design, and help to reduce the color strips and the chromatic aberrations for improve 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 representation.
The true macro design offers a maximum real-size magnification of 1: 1 along with a minimum focusing distance of 10.2 "to suit work with foreground subjects.
A super multilayer coating has been applied to the lens elements to minimize the reflection and ghost image of the lens and contribute to producing contrast-rich and neutral-color images, even in backlight conditions.
The rounded diaphragm of nine blades contributes to a soft and pleasant bokeh quality.
The coreless DC motor is used for fast and accurate autofocus performance. In addition, an updated focus algorithm, a full-time manual focus override, a large rotation angle and a cable focusing system allow for a greater and controllable focus adjustment.
The lens is constructed with a thermally stable composite material (TSC), together with traditional metals, for greater precision and use in wide temperature variations.

The bayonet mount is made of brass to ensure accuracy and durability. In addition, the rubber seal is incorporated into the design of the holder to make it resistant to dust and splashes.
Compatible with the optional DG EM-140 macro ring flash when used in conjunction with the 65mm macro macro flash adapter for uniform illumination at close working distances.
Compatible with optional TC-1401 and TC-2001 teleconverters to extend the effective focal length of the lens while retaining auto-focus functionality.
This lens is compatible with the optional Sigma USB cradle to adjust the different lens characteristics and update your firmware.
