Overview

• The APS-C 12mm F1.4 comes in Sony E, Canon RF and Fujifilm X mounts, delivering an 18mm full-frame-equivalent view (about 19mm on Canon RF).
• Its optical design includes 14 elements in 12 groups with three aspherical and two SLD elements, a nine-blade iris, 62mm filters, and correction for sagittal coma flare aimed at astrophotography.
• Video-friendly features on the 12mm include a stepping-motor AF, minimized focus breathing, an aperture ring on all mounts, and dust/moisture resistance with a water- and oil-repellent front coating.
• The full-frame 200mm F2 DG OS Sports for Sony E and L-mount uses HLA autofocus and OS2 stabilization rated to 6.5 stops, with standard and panning modes, an 11-blade diaphragm, a 105mm filter thread, and a 1,820g build.
• Sigma and reporting describe the 12mm as the widest F1.4 in the company’s APS-C prime lineup and present the 200mm F2 as a first-of-its-kind bright 200mm prime for full-frame.
