Another ‘S Line’ high-performance model for Nikon's full-35mm mirrorless camera system, the new Nikkor Z 24-70mm f2.8 zoom is clearly an important addition to the Z mount line-up, being a staple lens for a great many photographers. It’s around 25 percent smaller than Nikon’s current F mount model (which, it has to be said, is a big lens) and 18 percent lighter. The optical construction comprises 17 elements in 15 groups, of which four elements are aspherical types to correct for distortion and two are made from ED glass to minimise chromatic aberrations. Nikon claims the lens is “virtually vignette-free” across its entire zooming range, even at maximum aperture.
In addition to Nikon’s ‘Nano Crystal Coat’ anti-reflection multi-coating, the 24-70mm has a new ‘ARNEO’ coating which is claimed to be even more effective at reducing flare and ghosting.
The barrel is fully weather-sealed and fluorine coatings have been applied to the exposed surfaces of the front and rear elements to repel moisture and grease, and also assist with easier cleaning. There are three control rings, with a dedicated manual focusing collar now separate from the customisable multi-function ring. Additionally, there’s a customisable ‘L-Fn’ button which can be assigned one of 20 functions and is now accompanied by a small OLED-type display panel for showing the focusing distance, depth-of-field, aperture or focal length.
Autofocusing is performed via a stepping motor (STM) and Nikon’s ‘Multi-Focus System’ which employs two actuators to move two focus groups simultaneously, enabling the lens to achieve focus rapidly from nearly any distance, including for close-up shooting. The minimum focusing distance is 38 centimetres. The STM focusing drive is quieter and also allows for smoother, more linear adjustments, especially when shooting video. Additionally, Nikon says the zoom’s optical design minimises focus breathing which is also advantageous when shooting video.
The new Nikkor Z 24-70mm f2.8 S will be available in Australia from April, and local pricing has yet to be announced. For more information visit http://www.nikon.com.au
