Nikon 400mm f2.8G ED VR AF-S Nikkor brand_Kirk this one will definitely doWhen a 300mm f2. 8 just won't do, you can turn to this Nikon 400mm f2. 8G ED VR AF S Nikkor to do the job. Yes, it's much larger and heavier, but there's no substitute for the extra reach. Fast, accurate focusing and an effective image stabilizer make this a formidable performer; glass has minor dust, but is free of haze or fungus. Minor cosmetic wear. Includes lens hood, cap, and hardcase plus a much improved Wimberley Arca compatible lens foot.
