Nikon AF-S NIKKOR 300mm f/2.8G ED VR II Lens

Nikon AF-S NIKKOR 300mm f/2.8G ED VR II Lens (Used)
Overview
This is a top-tier, professional telephoto prime lens designed for maximum sharpness and performance, especially for fast-action photography (sports, wildlife). It is a highly valued piece of equipment.

Key Features (Standard)
Mount: Nikon F-Mount (Full-Frame FX).

Focal Length: Fixed 300mm.

Maximum Aperture: Constant, fast f/2.8.

Stabilization: Features effective Vibration Reduction (VR II) technology.

Build: Extremely rugged, professional-grade, and weather-sealed.

Critical Condition Issue
Fault: The autofocus is reported as squeaky and loud.

Technical Meaning: This noise almost always indicates that the Silent Wave Motor (SWM), which drives the autofocus, is either failing or is losing lubrication and grinding.

Impact: The AF speed may slow down, and there is a high risk of the motor failing completely, rendering the lens manual-focus only.

Recommendation: This lens requires professional service/repair (likely an SWM replacement) to ensure continued reliable autofocus function.
