Sigma 30mm f/1.4 EX DC HSM Lens for Canon EF

The Sigma 30mm f/1.4 EX DC HSM is a fast prime lens designed for APS-C sensor cameras, mounting via Canon EF and optimized for crop-sensor bodies in the EX series lineup. The f/1.4 maximum aperture makes it well-suited for available-light shooting and subject isolation, producing a field of view roughly equivalent to a 48mm lens on an APS-C body. Sigma’s HSM (Hypersonic Motor) autofocus system provides fast and quiet focusing with the option for full-time manual focus override. The optical design features an inner focusing system that keeps the overall lens length constant during focus. As a third-party lens, autofocus performance and compatibility may vary across Canon EF-mount body generations, and firmware updates or fine-tuning via Sigma’s USB Dock may be beneficial on some systems.
