DxOMark published their sensor review and test results of the Nikon AF-S NIKKOR 400mm f/2.8E FL ED VR Lens. This Nikon 400mm f/2.8E FL ED VR Lens gets 35 points overall DxOMark lens score on the full-frame Nikon D810, so it is a very high performer overall. Designed for professional sports and wildlife photographers, the Nikon AF-S Nikkor 400mm f/2.8E FL ED VR, is two pounds lighter but more rugged than its predecessor. It offers a fast maximum aperture that they say delivers pleasing Bokeh, and its low-light capabilities are claimed to be increased by four stops thanks to an advanced Nikon VR technology.

Conclusion From DxOMark:
“Nikon’s decision to switch from over several decades of ED glass in telephoto lenses to that of fluorite is intriguing initially, particularly as the use of fluorite in this type of lens is mostly associated with its archival Canon. However, as the results reveal, the decision appears to prioritize weight savings while mostly maintaining the optical quality of its predecessor. The new model is lighter overall than the Canon equivalent, yet it retains the meniscus protective lens. That’s a highly attractive feature, potentially protecting that expensive front fluorite element from damage. Whether all that is worth the initial premium over its predecessor (or the Canon offering) is arguable, however, prices are likely to fall over time and few professionals would argue that a lens like this isn’t well worth the investment in the long term.”
