The Tokina AT-X 17-35mm f/4 PRO FX Lens for Nikon Cameras is a versatile ultra-wide-angle zoom lens designed for use with Nikon full-frame digital or film cameras. Offering a wide focal range, a constant f/4.0 maximum aperture, and advanced optical features, this lens is well-suited for various photographic applications.

Key Features:

Full-Frame Coverage: The lens is designed for full-frame cameras, providing a focal length range of 17-35mm. At the wide end (17mm), it offers an impressive 103.9° angle of view, making it ideal for capturing expansive landscapes or shooting in tight spaces.

Constant f/4.0 Aperture: With a constant f/4.0 maximum aperture, the lens maintains a consistent level of brightness across its zoom range. This makes it suitable for low-light photography, allowing for versatile shooting conditions.

Optical Design: The lens features advanced optics, including two Super-Low Dispersion glass elements and one aspheric glass element. This optical design enhances contrast, sharpness, and effectively controls chromatic aberration, ensuring high-quality images.

One-Touch Focus Clutch Mechanism: Tokina’s exclusive One-Touch Focus Clutch Mechanism provides a quick and simple way to switch between autofocus and manual focus. The focus ring can be easily snapped forward for AF and backward toward the lens mount for manual focusing.

Water-Resistant Design: Improved seals make the lens “water-resistant” (not waterproof), offering durability in damp conditions. The lens also features a water-repellant optical coating, providing an additional layer of protection. However, it is not suitable for submersion in water or exposure to heavy rain.

Compact and Lightweight: Despite its wide focal range, the lens maintains a reasonable size and weight, making it a practical choice for various shooting scenarios.
