Sigma 30mm f/1.4 DC HSM Art Lens for Canon EF-Mount
High-Speed APS-C Prime Lens – Bright f/1.4 Maximum Aperture, 48mm Full-Frame Equivalent, Precision Hyper Sonic Motor (HSM) with Full-Time Manual Override, 1 Aspherical Element, Super Multi-Layer Coating, Thermally Stable Composite (TSC) Build with Brass Bayonet, Rounded 9-Blade Diaphragm, Includes Front Cap, Rear Cap & Dedicated Lens Hood (Good Condition / Minor Internal Dust & Faint Front Mark)

The Sigma 30mm f/1.4 DC HSM Art is a premium, high-speed normal-length prime lens engineered specifically for APS-C-format Canon EF-mount digital SLR cameras, delivering a versatile 48mm full-frame equivalent focal length. As part of Sigma’s prestigious Global Vision Art line, this lens is built to achieve exceptional resolving power, rich contrast, and artistic rendering. Its classic natural perspective makes it an ideal optic for everyday street photography, environmental portraiture, documentary projects, low-light events, and travel shooting.

Featuring an exceptionally bright f/1.4 maximum aperture, the lens excels in low ambient light while offering precise control over shallow depth of field for dramatic subject isolation. The optical construction includes 9 elements in 8 groups, incorporating one precision double-sided aspherical element to effectively control spherical aberrations, distortion, and astigmatism for edge-to-edge sharpness. Sigma’s Super Multi-Layer Coating minimizes flare and ghosting, preserving deep contrast and color neutrality in backlit scenes. Autofocus is powered by a Hyper Sonic Motor (HSM) with a rear focusing system, delivering fast, whisper-quiet, and accurate focusing alongside full-time manual focus override. Built with Thermally Stable Composite (TSC) material and a durable brass bayonet mount, the lens is also compatible with the optional Sigma USB Dock for custom focus calibration and firmware updates.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: COMPLETE ART PRIME LENS OUTFIT. Supplied with the Sigma 30mm f/1.4 DC HSM Art lens (Canon EF Mount), Sigma front lens cap, Canon/Sigma rear EF bayonet dust cap, and dedicated Sigma petal lens hood (LH686-01).

Exterior & Physical Status: GOOD CONDITION. The matte black TSC barrel, rubberized manual focus ring, distance scale window, AF/MF selector switch, and brass EF bayonet mount show standard cosmetic signs of handling, finish rubbing, and light surface marks consistent with regular pre-owned use.

Optical & Mechanical Status: FULLY FUNCTIONAL WITH MINOR COSMETIC BLEMISHES. The optical glass features one faint, superficial hairline mark on the front element surface and light internal dust particles within the barrel (tested and verified to have zero impact on optical clarity, resolution, contrast, or image exposure across all f-stops). The Hyper Sonic Motor (HSM) autofocus operates swiftly and quietly; the manual focus ring rotates smoothly; the electronic 9-blade circular aperture stops down accurately across all settings on compatible Canon EOS camera bodies.
