Nikon AF-S Nikkor 600mm f/4.0E FL ED VR
Number of lenses measured: 1
This lens' extraordinary precedessor is not really in need of improved optical performance, but some reduction in mass would surely be welcome. Nikon decided to do both. The new version has lost 1.25kg while offering significantly improved resolving power and contrast. Owners of the previous version are used to the weight of the lens and have adapted their supports, packs and muscle mass accordingly, so the moderate improvements in optical performance will, for many, not justify upgrading. But photographers looking for their first 600mm f/4.0 prime, this is the new benchmark. Our new #1 in the category.
