Nikon AF-S NIKKOR 120-300mm f/2.8E FL ED SR Overview
Speed, reach, and flexibility define the Nikon AF-S 120-300mm f/2.8E FL ED SR VR, an F-mount telephoto zoom characterized by an advanced optical design, quick focusing performance, and a bright f/2.8 constant maximum aperture. Fluorite and extra-low dispersion glass is used throughout the optical layout to effectively suppress a variety of aberrations for improved clarity, sharpness, and color accuracy throughout the zoom range.
Balancing the optical merits, this 120-300mm is also characterized by its inclusion of a Vibration Reduction image stabilization system that compensates for camera shake to enable sharper handheld shooting. A Silent Wave Motor also benefits producing sharp imagery, and affords quick and quiet autofocus performance along with full-time manual focus override. Additionally, a rotating tripod collar is featured to assist working with a support system and this lens utilizes an electromagnetic diaphragm to ensure consistent exposure stability when shooting at fast continuous speeds.

Short-Wavelength Refractive Lens
SR is a high- and specialized-dispersion glass lens that refracts light with wavelengths shorter than that of blue. By controlling short-wavelength light, the lens is able to achieve highly precise chromatic aberration compensation so that the colors in your images are more accurately reproduced. It also allows for more flexible optical designs, which allows for compact, lighter lenses to be designed.

ARNEO Coat
An anti-reflective coating developed by Nikon and used in conjunction with Nano Crystal Coat to further reduce ghost and flair effects caused by incident light entering the lens vertically. This allows for the outstandingly clear capture of images even when a light source is located within the frame.

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.
-
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 uses ultrafine, nano-sized* crystal particles to eliminate reflections inside the lens throughout the spectrum of visible light waves (380 to 780 nm) in ways that far exceed the limits of conventional antireflection coating systems. Nano Crystal Coat not only solves ghost effects caused by red light, which was incredibly difficult for previous systems. It also effectively reduces ghost and flare effects caused by light entering the lens diagonally. The result: clearer images.

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.
-
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.
-
Fluorine Coat
Photographers need gear that can withstand the elements. Nikon’s fluorine coat effectively repels dust, water droplets, grease or dirt, ensuring easy removal even when they adhere to the lens surface. Nikon’s fluorine coat endures a high frequency of lens surface wiping and its anti-reflective effect also contributes to the capture of clear images.
-
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.
-
Silent Wave Motor
AF-S NIKKOR lenses feature Nikon’s Silent Wave Motor (SWM). This technology converts “traveling waves” into rotational energy to focus the optics. This enables high-speed autofocusing that's extremely accurate and super quiet.
-
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.
-
Super Integrated Coating
Nikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses.
