The three new primes in the Sigma I series are the 24mm F3.5 DG DN | Contemporary (left), 35mm F2 DG DN | Contemporary (center) and 65mm F2 DG DN | Contemporary (right).

The three new lenses in the Sigma I series are the 24mm F3.5 DG DN | Contemporary, 35mm F2 DG DN | Contemporary and 65mm F2 DG DN | Contemporary. They join the existing 45mm F2.8 DG DN | Contemporary. All of these lenses have an all-metal body as well as metal internal components, a manual aperture ring and an AF/Manual focus mode switch.

The 24mm F3.5 DG DN | Contemporary has a minimum focusing distance of 4.3 inches and magnification of 0.5x, so while it’s not a true macro lens, it is capable of very close focusing for wide compositions with prominent foreground subjects. It’s a very compact lens with the L-Mount version measuring 2.5 inches in diameter and 1.9 inches in length. (The E-Mount versions of all three lenses are 0.1 inches longer than the L-Mount.) List price: $549.

The 35mm F2 DG DN | Contemporary offers a minimum focusing distance of 10.6 inches and a magnification ratio of 1:5.7. It measures 2.8 inches and diameter and 2.6 inches in length (L-Mount). List price: $639.

The 65mm F2 DG DN | Contemporary has a minimum focusing distance of 21.7 inches and a 1:6.8 magnification ratio. With a diameter of 2.8 inches and a length of 2.9 inches (L-Mount), it’s the largest of the three new lenses, but still very compact. List price: $699.

All three lenses have expected availability of mid-January 2021. For additional details, see the press release below.

New Lenses Offer Outstanding Performance, Superior Build Quality and Elegant Design

Ronkonkoma, NY – December 1, 2020 – Today, SIGMA Corporation introduces the I series of lenses for full-frame mirrorless cameras. Pairing both for exceptional optical performance and stylish, compact design, the three new lenses – the 24mm F3.5 DG DN | Contemporary, 35mm F2 DG DN | Contemporary, and 65mm DG DN | Contemporary – join the previously released 45mm F2.8 DG DN | Contemporary to establish a new benchmark in compact performance lenses. Featuring all-metal construction for durability and cutting-edge optical designs, the I series lenses are available in L-Mount and Sony E-mount.

“When it comes to mirrorless cameras, striking the proper balance between performance and size is even more crucial. We believe there is a growing demand for compact, high-performance, high-quality lenses,” reports SIGMA America President Mark Amir-Hamzeh. “The introduction of the I series of full-frame mirrorless-exclusive lenses answers this call. The I series represents a new option: premium compact primes that are stylish in appearance with impressive specifications and optical performance.”

Built to the mechanical and operational standards of SIGMA Cine lenses, in compact mirrorless form, the I series have outstanding feel and touch in the hand. The well-damped manual focus ring, aperture ring, and autofocus switches embody true functional beauty.
