Sigma 28-70mm f/2.8-4 D UC Lens For Nikon F

The Sigma 28-70mm f/2.8-4 D UC Lens for Nikon is a compact, lightweight standard zoom lens designed for Nikon F-mount film and digital SLR cameras, offering a bright f/2.8 aperture at the wide end in a notably compact, travel-friendly package. It’s a practical, versatile option for landscape, travel, and general-purpose photography, well suited to photographers who want standard-zoom coverage without excess bulk.

Optically, the lens covers a 28-70mm focal range with a variable maximum aperture of f/2.8 at the wide end narrowing to f/4 at full telephoto, delivering a 75.4° to 34.3° angle of view. The optical construction incorporates an aspherical lens element to help correct distortion, along with multi-layer coating to minimize flare and ghosting while contributing to optimum color balance. A minimum focusing distance of 19.7 in. (50cm) is maintained consistently across the entire zoom range, yielding a maximum magnification of 1:6.5, and the lens uses an 8-blade diaphragm.

As a D-type lens, it transmits distance information to compatible Nikon camera bodies, improving the accuracy of 3D matrix metering and flash exposure calculations. Autofocus relies on the camera body’s built-in focus motor rather than an internal ultrasonic or stepping motor, since this lens does not include its own AF drive system; autofocus will not function on Nikon bodies lacking a built-in focus motor, such as the D40 and D60. Zoom and focus are controlled via a two-touch design on the lens barrel.

Build quality centers on a lightweight plastic barrel construction, keeping the overall lens compact and easy to carry, with an overall length of approximately 2.4 in. (60mm) and a weight of approximately 245-278g depending on the specific production version. The lens accepts a 58mm filter thread and typically ships with a dedicated lens hood.

As a full-frame-compatible lens, the Sigma 28-70mm f/2.8-4 D UC produces its standard 28-70mm field of view on full-frame Nikon F-mount bodies and an effective, narrower field of view on Nikon’s DX-format (APS-C) cameras.
