Nikon AF-S NIKKOR 14–24mm f/2.8G ED This is Nikon's legendary professional ultra-wide-angle zoom — one of the lenses that, along with the 24-70/2.8 and 70-200/2.8, completes the classic "holy trinity" of pro zooms. The constant f/2.8 aperture across the entire 14–24 mm range makes it equally capable for landscape, architecture, interiors, astrophotography and event work in dim conditions. Its optical formula uses Extra-low Dispersion (ED) and aspherical elements, and it carries Nikon's premium Nano Crystal Coat to minimise flare and ghosting — a critical feature given the bulb-like front element. The lens is a "gold ring" pro-grade Nikkor with the gold "N" Nano Crystal Coat badge clearly visible on the side. Autofocus is driven by Nikon's Silent Wave Motor (SWM) with full-time manual override (M/A), and focusing is internal (IF). Because of its bulbous front element, it does not accept conventional screw-in filters; instead, it has a built-in petal-shaped lens hood as an integral part of the design.
