Sigma I Series 90mm F2.8 DG DN | Contemporary – Premium Compact Mid-Telephoto Prime for Mirrorless Systems

Uncompromising performance in an ultra-compact form. The I Series redefines mirrorless photography.

The Sigma I Series 90mm F2.8 DG DN | Contemporary is a high-performance, full-frame-compatible mid-telephoto lens, crafted for mirrorless camera users seeking premium optical results and a tactile, beautifully built photographic experience. Designed to complement the compact nature of mirrorless systems, this lens delivers exceptional clarity and fine detail in a lightweight, elegant body — perfect for portraiture, close-ups, travel, and cinematic video production.

Part of Sigma’s innovative I Series, the 90mm F2.8 blends technical precision with intuitive design, offering a unique shooting experience that goes far beyond simply taking pictures.

Designed for a New Generation of Mirrorless Shooters

Mirrorless cameras have transformed modern photography with their smaller bodies and advanced features. The Sigma 90mm F2.8 DG DN is tailored to these systems, offering outstanding resolution, smooth bokeh, and precise handling in a body that matches your camera’s size and style.

At a time when smartphone cameras dominate casual photography, the I Series stands apart — designed for photographers who want their gear to be both functional and inspirational.

Advanced Optics in a Truly Compact Body

Despite its compact footprint, the 90mm F2.8 packs serious optical technology:

• Five SLD elements reduce axial chromatic aberration for colour-accurate, razor-sharp results

• A glass-moulded aspherical element controls spherical aberration and field curvature

• Excellent sagittal coma correction supports crisp rendering of fine point light sources — ideal for night scenes or detail-oriented compositions

• Minimum focusing distance of 50cm and 1:5 magnification for macro-style shooting

By leveraging in-camera correction features found in mirrorless bodies, Sigma’s designers were free to focus on optical characteristics that matter most, reducing weight and enhancing clarity.

All-Metal Construction, Cinematic Feel

The 90mm F2.8 DG DN continues the I Series tradition of full-metal build quality, using high-precision aluminium components for both the exterior barrel and internal structures. This gives the lens a premium, tactile feel and durability for daily use. Details like the knurled aperture ring, smooth manual focus action, and precision-machined hood deliver a sense of quality rarely found in compact primes.

It shares the same 64mm diameter and 55mm filter thread as the 24mm F3.5 and 45mm F2.8 DG DN lenses, making it part of a beautifully matched, high-performance trio that weighs just 740g combined (L-Mount) — ideal for photographers and filmmakers who travel light but shoot seriously.

Optimised for Still and Video

Equipped with a stepping motor AF system, the 90mm F2.8 delivers fast, quiet, and highly accurate autofocus, supporting face/eye detection AF and smooth focus transitions in video. This makes it an ideal mid-telephoto lens for hybrid content creators.

Signature Magnetic Metal Lens Cap

The I Series includes a dedicated magnetic metal lens cap, offering a stylish and secure alternative to traditional plastic caps. For added convenience, the CH-11 magnetic cap holder (sold separately) clips to a belt or bag, keeping your cap safe and always within reach — a thoughtful detail that enhances every shoot.
