f/2.8G
The ED lens was released at the same time as Nikon D300. When used with Quan Huafu D700, it can reach a wide angle of 14 mm, so there is no need to worry about the magnification conversion of the lens. 【AF-S
14-24 mm
f/2.8G
ED lens (II)] ED lens that has been popularized on Nikon's mid-range and above lenses. Because the wavelengths of visible light are different, for example, the longest red light wave is 640-780 nm, while the shortest purple light wave is only 380-430 nm, and the refractive index of light with different wavelengths passing through the optical lens is also different, so it is naturally impossible to converge on the same plane, which is the reason why the purple edge phenomenon plagues many digital cameras. However, the ED glass has an abnormal chromatic refractive index, so the light passing through the ED lens can still converge on the same point accurately, so it is called ultra-low dispersion. ED lens can also be called one of Nikon's housekeeping skills. At the same time, there is a Nano on the lens.
transparent
Coating a nanocrystalline coating. This coating eliminates the internal lens reflection of various wavelengths, and effectively reduces the image ghost and glare unique to ultra-wide-angle lenses.
