Sigma 70mm f/2.8 DG Macro Art (EF)

The Sigma 70mm f/2.8 DG Macro Art Lens for Canon EF mount, available at Lightbulb Rentals, is designed to excel in close-up photography with its true 1:1 macro capability. This means it can capture subjects at life-size reproduction ratios when focusing as close as 10.2 inches. Its optical design is sophisticated, featuring two F Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, one anomalous partial dispersion/high refractive index element, and two aspherical elements. Together, these elements effectively minimize chromatic and spherical aberrations, ensuring images are sharp, clear, and accurately colored throughout the frame.

A Super Multi-Layer Coating on the lens elements reduces flare and ghosting, enhancing contrast and color fidelity, especially in challenging lighting conditions. The lens boasts a rounded nine-blade diaphragm that contributes to a smooth and pleasing bokeh, ideal for isolating subjects against soft, blurred backgrounds.

For focusing, the lens utilizes a coreless DC motor that delivers fast, accurate, and quiet autofocus performance. It also supports full-time manual focus override, allowing photographers to fine-tune focus manually at any time. The lens's physical construction includes Thermally Stable Composite (TSC) material and traditional metals, ensuring durability and stability in various environmental conditions. A brass bayonet mount enhances precision and durability, while rubber sealing protects against dust and moisture, making it suitable for outdoor use.

As part of Sigma's Art series, renowned for its high optical performance and suitability for creative and artistic applications, the 70mm f/2.8 DG Macro Art Lens is designed for full-frame Canon EF-mount cameras. It also offers compatibility with APS-C models, providing an equivalent focal length of approximately 105mm. Optional accessories like the EM-140 DG Macro Ring Flash and TC-1401 / TC-2001 Teleconverters further enhance its versatility for macro photography and extended focal length needs while maintaining autofocus functionality.
