Sigma 28-105/2,8 DG DN Sony E/FE

Harness the power of this versatile and portable F2.8 optic with an extended 28-105mm focal range – a standard zoom that goes well beyond standard.

The SIGMA 28-105mm F2.8 DG DN | Art is not just another standard zoom lens. With a powerful wide-angle to medium telephoto focal length and a bright F2.8 aperture throughout, this full-frame mirrorless zoom combines outstanding optical performance, superb build quality and a range of pro-grade features to make it one of the most versatile optics on the market for mirrorless systems.  

The lens is built to tackle a huge range of subjects and situations, from expansive low-light landscapes to portraits with big, beautiful bokeh, and thanks to SIGMA’s latest optical technology and the use of large diameter elements including FLD, SLD and five aspherical elements, it is able to do so with superb clarity and sharpness.

A linear motor HLA for rapid and accurate AF focus

The lens incorporates a linear motor HLA (High-response Linear Actuator) that delivers a maximum drive speed, ensuring responsive, precise and smooth AF. With its high level of quietness, the motor also provides noise-free video capability.

An aperture ring for improved ergonomics

For quick changes to exposure, or a more traditional way of shooting, the lens is equipped with a dedicated aperture ring, allowing the user to change aperture via the lens if preferred. An aperture ring click switch is a useful tool for film-makers, and a lock switch helps ensure the aperture ring is not knocked out of its setting accidentally.

Zoom lock switch to keep the zoom ring secure

The lens is equipped with a zoom lock switch that holds the zoom mechanism in place at its wide end, preventing it from extending unintentionally under its own weight when carried. The lock can be released by the switch, or by turning the zoom ring for a faster and more flexible workflow.

Weather-resistant structure for challenging conditions

The lens has a dust- and splash-resistant structure* that keeps it free of contaminants in harsh outdoor environments. The front element also features a water- and oil-repellent coating that helps keep it clean in adverse shooting conditions.

* The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable. 

Smarter design means lower weight

Constant F2.8 zoom lenses can be heavy, but by optimising the design and materials of each part of the SIGMA 28-105mm F2.8 DG DN | Art, SIGMA has achieved a remarkably light weight of less than 1kg. The use of magnesium-alloy rather than aluminum for the lens barrel around the mount has reduced the weight of these parts alone by two-thirds, while ensuring rigidity.

The pinnacle of optical quality in a zoom 

Through the effective arrangement of 5 SLD elements and 3 aspherical elements, aberrations are rigorously corrected. Axial chromatic aberration, which is particularly noticeable with large-aperture lenses, has been thoroughly suppressed, and the lens delivers clear images with minimal coloration, from sharply focused details to large, smooth bokeh.

Minimal focus breathing

Vital for film-makers who demand consistent framing, the lens has been designed to keep focus breathing to a minimum. This ensures that any changes to the angle-of-view due to focus shift are minimized across the entire zoom range, ensuring natural-looking focus pulls when recording video, and easier image alignment when focus stacking.

Designed to minimize flare and ghosting 

Using advanced simulation technology, flare and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions. In addition, SIGMA’s Nano Porous Coating and Super Multi-Layer Coating have been applied to further suppress flare and ghosting.
