Third-party lens manufacturers do a lot of research before embarking onto costly lens development. Not only do they do technical research to be able to manufacture a lens that is of high quality but cheaper than what’s already offered by the camera manufacturer, but they also do a lot of marketing research to decide which system to build lenses for. After all, they want their lenses to be bought and used. They don’t really care about the camera brand as long as there will be a market for their lenses. As consumers, this gives us confidence that we are investing in systems that will last a long time.
SIGMA believes Sony’s full frame E-mount mirrorless system and Leica’s full-frame L-mount mirrorless system are two systems worth developing lenses for. The I-series lenses promise exceptional optical performance in a stylish, compact design. Besides the current 45mm F2.8 DG DN | Contemporary, SIGMA is adding 3 new lenses: the 24mm F3.5 DG DN | Contemporary, 35mm F2 DG DN | Contemporary, and 65mm F2 DG DN | Contemporary.
SIGMA Introduces Full-Frame Mirrorless I series Premium Compact Prime Lenses
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 F2 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.
The I series is being announced with 3 new lenses:
- 24mm F3.5 DG DN | Contemporary (MSRP $549)
- 35mm F2 DG DN | Contemporary (MSRP $639)
- 65mm F2 DG DN | Contemporary (MSRP $699)
The three new lenses will be available for sale through authorized US retailers in mid-January, 2021.
The 45mm F2.8 DG DN | Contemporary, available now (MSRP $549), is also part of this series.
Key I series Lens Features:
All I series lenses feature an all-metal body, with high-precision metal internal parts, and a metal lens hood. The 24mm F3.5 is a petal-type hood.
- All I series lenses feature a manual aperture ring and knurled surfaces for an enjoyable tactile experience.
- The 35mm F2 and 65mm F2 lenses feature a newly-designed arc-type auto/manual focus mode switch.
