Nikon AF-S 300mm f/4E PF ED VR
A new Phase Fresnel element helps shrink Nikon’s new 300mm lens
Nikon’s replacement for its AF-S 300mm f/4D IFED was announced at the CES show in Las Vegas in January. It includes a Phase Fresnel (PF) element to combat chromatic aberration, which also enables the lens to be shrunk significantly in size. In fact, the total number of component elements has been lowered from 16 in 10 groups to just 10 in six groups, and as a result the weight has also been reduced by about half, to just 755g.
The new lens is also just 147.5mm long instead of 222.5mm, making it easier to carry and use, so if it lives up to Nikon’s claims for image quality, it could prove very popular with sport and wildlife photographers wanting to travel light. Although the maximum diameter of the lens has reduced by 1mm to 89mm, the filter size is still 77mm.
The lens also has Nikon’s VR technology, effective to a claimed 4.5EV, to reduce the impact of camera shake, and a fluorine coating repels water.
