AF-S NIKKOR 300mm f/4E PF ED VR AF-S Digital SLR Lens Close the distance with this FX-format 300 mm lens. As the first F-mount NIKKOR to be equipped with a phase Fresnel element, it offers the ultimate balance of compact build, telephoto reach, & high image quality. High-performance telephoto lens:offers 300 mm focal length & f/4 maximum aperture. (450 mm focal length when used with a Nikon DX-format SLR.) Phase Fresnel element:this telephoto lens delivers great optical performance & boasts a remarkably compact build. Use of a phase Fresnel (PF) lens element noticeably reduces the weight, without degrading image quality. Vibration Reduction (VR): with SPORT mode. VR minimises the effects of camera shake & lets you shoot at shutter speeds up to 4.5 stops slower.¹ SPORT VR mode delivers a stable viewfinder image when shooting high-speed movement, & allows a continuous shooting frame rate with reduced release time lag, similar to those that are possible when VR is turned off. Advanced optical performance: Nano Crystal Coat effectively reduces ghost & flare, increasing the clarity & contrast of images. An ED (extra-low dispersion) glass element minimises chromatic aberration. Electromagnetic diaphragm: enables consistent, more precise exposures, especially when shooting at high frame rates. Fluorine coating: actively repels water, dust, & dirt without compromising image quality. The coating enhances durability & makes it easier to clean the glass without damaging the surface. Minimum focus distance: 1.4 m. RT-1 tripod collar ring (optional accessory): enables the lens to be rotated freely for smooth transition between vertical & horizontal orientation.
