Sigma 30mm F1.4 Art Lens for APS-C Canon

This lens is built for APS-C format Canon EF-S mount cameras, delivering a 48mm equivalent field of view. It suits photographers who want a bright normal prime for everyday creative work. The fast f/1.4 aperture supports shallow depth of field and low-light shooting. It is not for full-frame users or shooters needing zoom flexibility.

Bright f/1.4 Aperture for Sustained Low-Light Work

The wide maximum aperture gathers ample light across extended sessions, keeping shutter speeds usable without pushing ISO. Consistent exposure holds during long events or indoor series. The HSM autofocus tracks smoothly without hunting when the light drops. It is not for action sequences demanding continuous high-speed burst tracking.

Optical Design Controls Flare and Aberration

One aspherical element reduces spherical aberration and distortion for sharp rendering across the frame. Super Multi-Layer Coating cuts flare and ghosting in strong backlight, preserving contrast. The ultrasonic motor runs quietly during focus pulls. It is not for users requiring weather sealing or image stabilisation.

Questions about this item

Does the 30mm f/1.4 Art lens run hot or make noise during long shoots?

The Hyper Sonic Motor drives autofocus quietly and the lens has no active cooling, so it stays cool and silent during extended use.

What must I already own to use this Canon EF-S mount lens?

A Canon APS-C DSLR body with an EF-S mount and a 62 mm filter thread for circular filters.

Will the 301101 work on my older Canon EF camera?

Yes, it mounts on any Canon EF or EF-S DSLR; on full-frame bodies the 48 mm equivalent field of view applies and vignetting may occur.
