NIKON 24-70 Z F4 NIKKOR LENS

Nikon NIKKOR Z 24-70 mm f/4 

Covering a useful range of focal distances, the NIKKOR Z 24-70 mm f/4 S is a versatile zoom, ranging from wide-angle to vertical perspectives. Its maximum constant aperture of f/4 maintains constant exposure throughout the zoom range and also helps to make a more compact and lightweight alternative to an F/2.8 zoom. With regard to the optical design, an extra low aspheric dispersion element is used, in addition to three aspherical elements, to help reduce aberrations and chromatic distortions throughout the zoom range for high clarity and image brightness. Both Nano Crystal and Super Integrated coatings have also been applied to control flashes and phantom effect for greater contrast and color reproduction in bright and backlit light conditions.
As a complement to the optics, a step-by-step engine provides fast, quiet, and accurate auto-focus performance along with a full-time manual focus override to accommodate still images and video applications. A programmable control ring can be configured for intuitive adjustment in a variety of camera and exposure settings. In addition, the lens has a non-button retractable cylinder to achieve a more compact form factor when not in use.
The standard zoom covers a wide-angle to vertical range and is designed for cameras without Z-mount Mirror in FX format.
F/4 's constant maximum aperture delivers constant performance across the entire zoom range and also contributes to relatively lightweight and compact form factor design.
It incorporates an exclusive ultra low aspheric dispersion element in the optical design, along with three additional aspherical elements, to greatly reduce chromatic and spherical aberrations, distortion, coma (Comática aberration) and flashes To achieve constant edge-to-border clarity and lighting. .
A Nano Crystal layer was applied, along with a super-integrated coating, to the lens elements to minimize the surface and internal reflexes for a marked reduction in lens reflex and phantom effect.
The step-by-step engine delivers incredibly smooth, quiet, and fast auto-focus performance that fits well with still images and video applications. It is also possible to override the full-time manual focus and use an internal focusing design, where only internal lens groups move during focus, to maintain the total length of the lens during use and to promote more focus speeds Fast.
The programmable control ring is set by default to adjust the manual focus, but it can also be used to control opening or exposure compensation.
The specialized electromagnetic aperture mechanism provides greater stability of exposure control that is especially beneficial when working with fast continuous trigger speeds.
The seven-bladed, rounded diaphragm promotes a pleasant approach quality that benefits the use of shallow depth of field and selective focus techniques.
The exposed elements present a fluorine coating that protects the optical system against dust, grease and water droplets.
The cylinder of the dust-and moisture-resistant lens benefits the use of the lens in inclement conditions.
The non-button retractable design maintains a compact form factor when the lens is not in use.
