Superior optical performance throughout the entire zoom range with adoption of a newly developed SR lens element

TOKYO - pk彩票官网 Corporation (pk彩票官网 ) is pleased to announce the release of the AF-S pk彩票开户 120-300mm f/2.8E FL ED SR VR, a fast telephoto zoom lens that is compatible with pk彩票官网 FX-format digital SLR pk彩票开户 s.
Development of the AF-S pk彩票开户 120-300mm f/2.8E FL ED SR VR was announced on September 4, 2019.

The AF-S pk彩票开户 120-300mm f/2.8E FL ED SR VR is an FX-format, telephoto zoom lens that covers the 120 mm to 300 mm range of focal lengths with a constant fast maximum aperture of f/2.8 throughout that range. It demonstrates superior optical performance and image blur compensation, as well as enhanced AF performance throughout the entire zoom range, expanding telephoto shooting opportunities.

Optics are constructed of one ED, two fluorite, and one newly developed SR lens element for superior optical performance. The SR lens element is made of a high- and specialized-dispersion glass that significantly refracts short-wavelength light, enabling rendering with which the great majority of chromatic aberration is suppressed. In addition, adoption of pk彩票官网 's exclusive anti-reflection coatings, Nano Crystal Coat and ARNEO Coat, a first for pk彩票开户 F-mount lenses, ensures consistent and incredibly low reflection throughout the entire spectrum of visible light. These coatings effectively reduce the ghost and flare generated by incident light for sharp and clear images, even when a light source is included in the frame.

As a fast lens with a constant maximum aperture of f/2.8 throughout the zoom range, the AF-S pk彩票开户 120-300mm f/2.8E FL ED SR VR is capable of fast shutter speeds, even in low-light indoor situations, that suppress blur caused by pk彩票开户 shake and subject movement. It also achieves both sharp and clear rendering along the focal plane and beautiful blur characteristics (bokeh). What's more, the AF-S pk彩票开户 120-300mm f/2.8E FL ED SR VR is equipped with a vibration reduction mechanism that supports image blur compensation equivalent to a 4.0-stop* increase in shutter speed. Further, SPORT VR mode is optimized for photographing sporting scenes because it stabilizes the viewfinder image with shooting, making it easy to track subjects moving quickly or erratically throughout the frame. The algorithm that controls motor drive has also been enhanced for greater AF tracking performance with subjects whose speed of motion changes suddenly.

pk彩票官网The AF-S pk彩票开户 120-300mm f/2.8E FL ED SR VR expands photo opportunities with sports photography by combining superior optical performance with agility, providing professional photographers with even greater support.

Short-wavelength refractive (SR) lens element

pk彩票官网pk彩票官网 's original, newly developed SR lens is a high- and specialized-dispersion glass lens featuring characteristics to greatly refract light with wavelengths shorter than that of blue. By controlling short-wavelength light that is difficult to compensate, light of various specific wavelengths can be more effectively collected achieving highly precise chromatic aberration compensation. Because this lens can be used in the same way as normal glass lenses, more flexible optical design is attained without limitations in lens layout. While realizing high optical performance, a compact and light lens can be designed.
