Normal-Range Prime. With an angle of view equivalent to 48mm, this lens is a great choice for a wide variety of photographic styles. The f/1.4 aperture provides great low-light shooting capabilities, and a fast Hyper Sonic Motor autofocus system ensures sharp, in-focus images.

Rear Focusing. The lens’s rear-focus system prevents focus-dependent variation in aberration, meaning that the entire image is high quality. This also means the barrel remains stationary at all times, which is great news for filter users. The Sigma 30mm f/1.4 DC HSM A1 offers a 11.8-inch minimum focusing distance and a 1:6.8 maximum magnification ratio.

High-Quality Build. Sigma’s proprietary MTF measuring system (A1) uses their 46MP-resolution Foveon direct image sensors to bring previously undetectable high-frequency details within the scope of their quality-control inspections, allowing improved manufacturing tolerances with improved image quality and performance.

Dock Compatible. As part of Sigma’s Global Vision series, this lens is compatible with the Sigma USB Dock for Canon EF Lenses (separate rental item), allowing you to adjust certain parameters through the Sigma Optimization Pro software.
