Introduction of Nikkor AF 24-85mm f2.8-4:
The Nikkor AF 24-85mm f/2.8-4D IF is one of two 24-85mm zooms in the present Nikon lens line-up. The lens has apparently a main concern on a large maximum aperture whereas its sibling, the AF-S 24-120mm f/3.5-5.6 VR has an importance on range. The Nikkor is a full format lens with an aperture ring and functional on all Nikon film and digital SLRs. The Nikkor AF-S 24-85mm f/3.5-4.5G VR is a reasonably priced common purpose zoom that's friendly with full-frame Nikon FX bodies. Announced in June 2012, it's perhaps the successor to the Nikon AF 24-85mm f/2.8-4D from 2000. It's optically a little slower but now sports Vibration lessening to neutralize camera shake and as an AF-S model it'll autofocus on any Nikon body.
A reasonable general-purpose zoom for exclusive full-frame bodies may seem like a strange combination, but the AF-S 24-85mm provides a practical range and could complement an accessible selection of primes. You could regularly mount it on a DX body now and enjoy 36-128mm corresponding coverage with an improvement to full-frame penciled for the future. It also attractively suggests a more reasonable full-frame body. With this most likely being the natural kit lens.
With the addition of the AF-S 24-85mm f/3.5-4.5G VR, Nikon now offer three stabilized FX general-purpose zoom lens starting at a straight wide angle and zooming in to various degrees of tele-coverage: the 24-85mm, 24-120mm and 28-300mm.
Typical for older AF Nikkor the lens has no inside AF motor and relies on a slotted drive screw operated by the camera. The fairly noisy AF is extremely fast and practically accurate because of the large aperture. The lens has two focusing modes - a normal mode where the lens can focus between 0.5m and perpetuity and a devoted macro mode activated via a switch. The focus path within the "standard" setting is extremely short - all the focus action happens on a ~20 degree turn of the focus ring. This is excellent for the AF speed, less so for manual focusing which is pretty delicate. The macro mode enables focusing down to 0.21m with a max aim magnification of 1:2 at 85mm - pretty impressive for a standard zoom but you should not really wait for the quality to be as good as with a native macro lens the Nikkor has no balanced scheme. Regrettably the focus ring rotates during AF operations - this design is a little old by today´s standards.
