Sigma 50mm DG HSM Lens for Canon EF Standard SLR Cameras F1.4 Mount, Full-Frame

To achieve high resolution, aberrations that affect image quality, such as sagittal coma flare and chromatic aberration, are thoroughly corrected, achieving high-definition images without blurring even at maximum aperture. The internal mechanism is equipped with an ultrasonic motor (HSM) that achieves high-speed and quiet AF. The AF algorithm has been improved for smoother AF. Full-time manual focus is also available, allowing you to fine-tune the focus simply by turning the focus ring after focusing. The adoption of a super multi-layer coating reduces flare and ghosting, enabling high-contrast images even in backlit situations.
