Nikon 300mm f/4E PF ED VR AF-S Nikkor Lens

The power of a Phase Fresnel lens in a revolutionary 300mm. 
Introducing a thrilling new 300mm f/4 prime lens capable of changing the way pro and serious enthusiasts shoot. At just 147.5mm long and 755g over 30% shorter and 1.5lbs lighter than its predecessor the AF-S NIKKOR 300mm f/4E PF ED VR is the world's lightest 300mm full-frame AF lens. (As of January 5, 2015. Statement based on Nikon research.) The secret to its remarkable size? A Nikon-designed Phase Fresnel (PF) lens element, a first for the NIKKOR DSLR lens lineup. But handling isn't the only advantage; the PF element also performs brilliantly achieve new levels of sharpness and clarity with virtually no chromatic aberration or ghosting. Whether you shoot fashion, portraits, nature, wildlife, sports, action or today's big stories, the AF-S NIKKOR 300mm f/4E PF ED VR will help you capture stunning views of the decisive moment. 

Thrilling new optical performance 
The AF-S NIKKOR 300mm f/4E PF ED VR is a cutting-edge lens engineered to draw peak performance from high-resolution full-frame cameras. The Phase Fresnel element nearly eliminates chromatic aberration on its own. When combined with an Extra-low Dispersion (ED) glass element and Nano Crystal Coat (N), it delivers strikingly clear, accurate images. Nikon's Silent Wave Motor (SWM) provides ultra-quiet, ultra-fast autofocusing with seamless manual override (just spin the focusing ring), and a Fluorine coating on the front lens element effectively repels dust, water, grease or dirt, ensuring easy cleaning. 

Speed, precision and versatility 
The AF-S NIKKOR 300mm f/4E PF ED VR is a quintessential prime lens that belongs in the serious photographer's bag. Its fast f/4 maximum aperture and rounded nine-blade diaphragm produce beautiful bokeh. A highly accurate electromagnetic diaphragm mechanism ensures consistent exposures, especially when shooting at high frame rates. And for greater reach, the AF-S NIKKOR 300mm f/4E PF ED VR is compatible with most Nikon Teleconverters. Work in nearly any light, at any distance, with outstanding sharpness and contrast. 

4.5 stops of Vibration Reduction 
The AF-S NIKKOR 300mm f/4E PF ED VR's Vibration Reduction (VR) feature provides an image stabilizing effect equivalent to a shutter speed increase of 4.5 stops* (in NORMAL mode; based on CIPA Standard). Capture sharp, clear handheld images in low light, of fast action and more. VR modes specifically designed for Sports & Action and Tripod Shooting deliver specialized image stabilization to match your situation. 

A/M 
A/M stands for Auto-Priority Manual Mode. This mode also enables an easy transition from autofocus to manual during AF operation. However, mode switch sensitivity has been altered to reduce the possibility of sudden unintentional switching to manual focus while shooting. 

Electromagnetic Diaphragm Mechanism 
An electromagnetic diaphragm mechanism in the lens barrel provides highly accurate electronic diaphragm or aperture blade control when using auto exposure during continuous shooting. With conventional D/G type lenses, the diaphragm blades are operated by mechanical linkage levers. 

ED (Extra-Low Dispersion) Glass 
An optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations. 

IF Lens 
A NIKKOR lens in which only the internal lens group shifts during focusing. Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances. These lenses will be designated with the abbreviation IF on the lens barrel. 

M/A 
Select NIKKOR lenses have a focusing mode which allows switching from automatic to manual focusing with virtually no lag time by simply turning the focusing ring on the lens. This makes it possible to seamlessly switch to fine manual focusing while looking through the viewfinder. 

Nano Crystal Coat 
Nano Crystal Coat 
An anti-reflective coating developed by Nikon that virtually eliminates internal lens element reflections across a wide range of wavelengths. Nano Crystal Coat solves ghost effects caused by red light and effectively reduces ghost and flare caused by light entering the lens diagonally. 

Phase Fresnel 
Phase Fresnel (PF) lens elements effectively compensate for chromatic aberration and ghosting when combined with ordinary glass lens elements. The PF lens element is based upon the Phase Fresnel lens, which appears to have a series of concentric circles engraved onto it. Utilizing a Phase Fresnel lens element allows Nikon engineers to use fewer lens elements, resulting in a more compact and lightweight lens. Due to the characteristics of a PF (Phase Fresnel) lens that utilizes the photo diffraction phenomenon, when there is a strong light source within the frame or when light enters the lens from outside of the frame, ring-shaped colored flare may occur according to shooting conditions. This phenomenon can be minimized with "PF Flare Control" to be included in Capture NX-D (ver.1.1.0 or later). For more information, see software Help/manual. Capture NX-D is available from the Nikon website. Be sure to keep your software up to date. 

Silent Wave Motor 
AF-S NIKKOR lenses feature Nikon's Silent Wave Motor (SWM), which represents a significant advance in AF lens technology. SWM uses ultrasonic vibrations rather than a gear system to focus the lens, providing incredibly smooth, silent and precise autofocus operation. 

Super Integrated Coating 
Nikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses.

Vibration Reduction 
A Nikon in-lens technology that improves image stability by automatically compensating for camera shake. Lenses that offer VR will feature the abbreviation VR on the lens barrel.
