NIKKOR Z 28-135mm f/4 PZ

This type of lens utilizes non-spherical surfaces on either one or both sides of the glass in order to eliminate certain types of lens aberration. These aspherical elements are particularly useful for correcting the distortion in wide-angle lenses. Such distortions are caused by variations in the magnification of the image, depending on its distance from the optical axis. Aspherical lens elements correct these distortions by continuously changing the refractive index from the center of the lens. Since the 1960s, Nikon engineers have established design theories and lens-processing techniques to refine the aspherical lens. In 1968, the OP Fisheye-Nikkor 10mm f/5.6 became the first interchangeable SLR lens incorporating aspherical lens elements. Since then, aspherical lenses have been an important part of the NIKKOR lens family, with every new addition to the lineup providing a new level of contrast, resolution and compact design. Hybrid aspherical lenses: made of a special plastic molded onto optical glass. Molded glass aspherical lenses: manufactured by directly pressing optical glass into a high-precision aspherical mold.

Nikon was the world's first camera maker to develop ED (Extra-low Dispersion) glass that could minimize prism-caused color dispersion. This low-dispersion ED glass also offers anomalous dispersion characteristics like calcium fluoride crystals, which consequently minimize the secondary spectrum. For lenses using normal optical glass, the longer the focal length, the more difficult it is to correct the chromatic aberration that causes color fringing. Nikon's ED glass, which effectively compensates for this kind of chromatic aberration, is employed in a wide range of NIKKOR telephoto lenses for superior reproduction.

Thanks to a diaphragm blade unit with driving mechanism incorporated in the lens body, the camera can accurately control aperture via electronic signals. This delivers stable aperture control (AE) constantly, even during continuous shooting^*.

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.

This is a system by which lens elements are divided into front, middle, and rear groups, and only the middle group moves with focusing. The total length of the lens does not change with focusing. AF speed can be increased for zoom lenses and telephoto lenses because the weight of the focusing group can be reduced.

Meso Amorphous Coat suppresses ghost and flare caused by incident light from any direction, including those entering the lens diagonally and vertically, to the utmost limit, demonstrating the highest anti-reflection performance in NIKKOR history. With this coating system, amorphous particles are interconnected and overlapped randomly to create a large number of air gaps termed mesopores. The many gaps within the coating form an ultra-fine mesoporous structure, attaining an outstandingly low refractive index. Additionally, a higher-precision base coat is employed to further enhance the anti-refection effect.

Motor operation is synchronized with pulse electric power, rotating one step per electric pulse. It offers high response and controllability for starting and stopping, and its simple mechanical structure allows for extremely quiet operation. Useful for video shooting and other times when operational noise from the lens is a concern.

Nikon's exclusive multilayer lens coating achieves high transmittance in a wider wavelength range. Even for zoom lenses with a large number of glass elements, this coating system effectively reduces the ghost and flare effects that are likely to occur in backlit situations, helping you achieve high-contrast images with rich gradation. With outstanding color balance and reproduction capability, superb optical performance can be achieved. Ghost and flare effects caused by internal reflections particular to digital cameras are also effectively minimized. This coating system is applied to all current lenses in the NIKKOR lineup.

The power zoom^* has been designed in pursuit of light and responsive operational feel. This function achieves smooth zooming at a constant speed and various options for zoom operation including via remote-control capabilities. That ensures comfortable photo shooting and video recording.
