Sigma 24mm f/1.4 DG HSM Art Lens for Canon EF Mount Cameras
Sigma's 24mm DG Lens is specifically designed to deliver the ultimate level of performance on full-frame DSLRs. It maximizes the abilities of both 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to help eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. The lens provides exceptionally high contrast along with subtle gradations in tone and color.
With class leading performance, this lens is ideal for wedding photography, landscape photography, videography, astrophotography, lowlight/indoor photography and event photography. The Sigma 24mm Art is compatible with the USB dock to update and customize and is also compatible with the Mount Conversion Service.
The lens comes with a Super Multi-Layer Coating that along with Sigma's optimized optical design reduces reflections between the image sensor and the lens surfaces. The large image circles of the lens ensure that there will always be enough peripheral illumination to avoid vignetting.
Quiet and Fast Autofocusing
The lens employs a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.
Minimized Sagittal Coma Flare
Sagittal coma flare is the aberration in which a point light source appears as a streak instead of a point, and it affects large-diameter lenses in particular. By positioning aspherical lens elements toward the rear of the 24mm f/1.4 DG HSM Art, the angle of incidence of light is adjusted for optimal power distribution. Even at wide-open aperture, you will enjoy outstanding image quality. Since streaking of point light sources toward the edges of the image is minimized, this lens is a powerful ally in photographing celestial bodies, nighttime.
Flare and Ghosting Reduction
From an early stage in the lens design process, flare, and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. Sigma’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
