The Nikkor AF 105mm f/2D DC is one of two Defocus Control lenses in the
Nikon lens line-up. DC lenses allow you to control the degree of spherical aberrations
or in simple words: you can emphasize the degree of foreground or background blur
(bokeh) beyond the sheer potential of a large aperture lens. Typical applications
which could benefit from a controlled bokeh are still-life and portrait photography.
The lens was released back in 1993 so it is one of the oldest Nikkors still in production
and as such a full format lens. On APS-C DSLR such as the D200 its field of view
is equivalent to 158mm on the classic full format.
The build quality of the lens is excellent thanks to combination of metal
and plastic parts with a Nikon "pro style" crinkle finish.
The length of the lens remains constant regardless of the focus setting
and the front element does not rotate due to an RF (Rear Focusing)
design. A nice and almost forgotten approach is the build-in lens hood
(telescope style). I would really wish that this old "fashion" will see a
The Nikkor features an independent ring (rather stiff) for switching between
AF and manual focusing - a dated and cumbersome approach compared modern AF-S
lenses. The lens has no internal AF motor and relies on a slotted drive screw
operated by the camera. As a result the AF generates a moderate
degree of noise but the AF speed is comparatively high. A rather annoying
aspect is the rather long min. focus distance of 0.9m.
