Nikon AF-S Nikkor 180-400mm f4E TC1.4 FL ED VR is the first Nikon lens with a built-in teleconverter, which is the successor of the 200-400mm model. The lens is supposed to be used for sports and wildlife photography.
After switching on the converter, the lens changes into the one with the focal length of 252-560mm. It of course reduces the brightness by one degree. After connecting to the cameras with the APS-C sensor, we get a much more interesting equivalent of focal length of 378-840mm. Unfortunately, then the lens is going to be darker.

The optical system of the new 180-400mm f4E consists of 27 lenses placed in 19 groups. One of them is a fluorite one (the coating responsible for cleanliness) and 8 of them are low-dispersion ones. The lens is also supposed to be sharper than average and a minimum focus distance is 200mm.
A 9-blade aperture and an effective system of vibration reduction with the effectiveness of 4EV has been used in the lens. Of course, in this class of lenses we have a possibility of switching between various modes.

Conventionally, a quiet ultrasonic AF motor is responsible for focus adjustment. We can reduce the focus distance up to 6m with the use of a button on the body. With this lens we can also use inserting filters.
This magnesium lens is neither compact nor light. Its weight is 3.5kg and it has the dimensions of 128x363mm.

And the most interesting part… As one could expect, the lens is not cheap. It costs $12399 and it’s going to be available in March. If you think that the price of this lens is cosmic, you should compare it to a slightly more expensive Leica Noctilux-M 75mm f/1.25 :-)
