1. Overview

The Nikon AF-S FX NIKKOR 24-70mm f/2.8G ED Zoom Lens is a high-performance, fast-aperture wide-angle to medium telephoto zoom lens optimized for both Nikon FX (full-frame) and DX (APS-C) format image sensors. It is engineered to deliver exceptional sharpness, contrast, and color, making it suitable for a wide range of photographic applications.

• Focal Length Range: 24-70mm, providing versatile coverage from wide-angle to standard telephoto.

3. Operating the Lens

3.1 Focus Mode Switch

The lens features a focus mode switch with two settings:

• M/A (Autofocus with Manual Override): Allows for quick switching from autofocus to manual focus by rotating the focus ring. This is ideal for fine-tuning focus after the camera has achieved initial autofocus.
• M (Manual Focus): For full manual control of focusing. Rotate the focus ring to adjust focus.

3.2 Zooming

To change the focal length, rotate the zoom ring on the lens barrel. The focal length can be adjusted from 24mm (wide-angle) to 70mm (telephoto).

3.3 Aperture

This lens features a constant maximum aperture of f/2.8 across the entire zoom range. This allows for consistent exposure settings and excellent depth-of-field control, regardless of the focal length selected.
