Nikon has announced a new full-frame lens with one of the longest names we've ever seen: the AF-S Nikkor 180-400mm F4E TC1.4 FL ED VR.
Besides its impressive range, the highlight of this hulking lens is its built-in 1.4x teleconverter. Taking a leaf out of Canon's book, the built-in converter boosts the focal range to 252-560mm with a corresponding 1-stop reduction in maximum aperture. If you're using this $12,000+ lens on an APS-C body, the equivalent focal range becomes 270-600mm without the TC and 378-840mm with it.
The lens features 1 fluorite and 8 extra-low-dispersion elements plus fluorine, Nano Crystal and Super Integrated coatings. It has 9 rounded aperture blades, a Vibration Reduction system that reduces shake by up to 4 stops and a minimum focus distance of 2 meters. As you'd expect, this magnesium alloy lens (that weighs almost 8 pounds / 3500 grams) is weather-sealed. Drop-in 40.5mm filters are supported.
As an added bonus, if you're using a camera with a 153-point AF system (D5, D500, D850) the outer row of AF points become cross-type sensors for improved coverage. A firmware update will be required in order for cameras to take advantage of this feature.
The AF-S Nikkor 180-400mm F4E TC1.4 FL ED VR will be available in March for a whopping (but unsurprising) MSRP of $12,399.
