Tokina AT-X 11-16mm f/2.8 Pro DX - unknown Mount

The original AT-X 11-16mm f/2.8 Pro DX is a widely acclaimed ultra-wide zoom for APS-C DSLRs. It is distinguished by its fast f/2.8 constant aperture, which is rare for this focal range, making it excellent for architectural work and night photography. The build quality is substantial, featuring Tokina's signature focus clutch for quick transitions between AF and MF. Note that the Nikon version of this original model lacks an internal motor, requiring a camera with a screw-drive motor for AF. Check the mechanical condition of the focus clutch, ensuring it slides easily without catching. SDS inspects the rear element carefully, as ultra-wide designs are sensitive to any rear-mount damage. We also check for consistent sharpness across the zoom range to ensure no internal elements have become misaligned through heavy use. Look for the presence of the original petal-shaped hood, as it is essential for controlling flare on this lens.
