Nikon AF-S Nikkor 600mm F4E FL ED VR Overview

Manufacturer description: The new AF-S Nikkor 600mm f/4E FL ED VR lens design significantly improves AF tracking performance, helping photographers to capture images of dynamic wildlife or athletes in precise clarity, even when subjects are moving erratically, at random speeds or at the camera. The lens also utilizes Nikon’s Electromagnetic Diaphragm, helping to maintain consistent exposure during high-speed burst shooting of fast action.
The addition of fluorite lens elements to the optical formula helps to reduce chromatic aberration, as well as decrease the overall weight of the lens, saving nearly three pounds (down to 8.3lbs/3.8kg). For extended shooting days in the field, the AF-S NIKKOR 600mm lens also employs magnesium alloy construction for enhanced durability and further weight reduction.
