Also referred to a different body in front of the lens compatibility, here to do a simple type of Nikon wide angle lens compatibility with the introduction to the friends are not familiar with some of the Nikon system reference.

Compatibility of the lens and the body we have to consider two issues: the focus and metering.

From the focus point of view, the Nikon SLR camera lens can be divided into three categories: manual focus (AI, AIS), body focus motor (AF, AF-D), focusing lens built-in motor (AF-I, AF- S). All modern digital cameras compatible with Nikon manual focus lens focus, that is there in the viewfinder focus confirmation display (green dot). Professional machine (a number and D700) there are two arrows left and right direction to provide focus auxiliary display. However, in non-full frame camera body the trouble of using manual focus lens is probably more a relatively small viewfinder and the non-frosted glass.

All modern digital cameras are also compatible with the body built-in motor AF lenses (AF-I and AF-S), including AF-S (silent ultrasonic motor) has become the mainstream of modern Nikon lenses automatically.

The remaining problem was the lens body focus motor (AF, AF-D), Nikon has produced over the past twenty years a large number of motor-driven focus lens body, to begin production until 1997 silent ultrasonic motor lenses. Although in recent years introduced new Nikon lenses are built-in lens motor, the market there are a lot of body-focus lens in the sale of motor drive, including the Nikon they were still for sale.

We can not know what the reason, the Nikon D40 start from some entry-body focus drive motor to cancel, so that these entry-level lens can not drive the motor body (non-AF-I, AF-S lenses). For the set of machines or consider purchasing the old lens users, they may not worry about do not even know these entry-level limitations. For the future there are users who buy the lens, the lens compatibility need to be concerned.

Finally, a Nikon camera body focus motor drive is AF 10.5/2.8G fish-eye, 2003 produced.

Another compatibility issue is the lens metering, manual lens metering precisely because all modern Nikon body supports AF metering, whether it is body-driven lens (AF, AF-D) or the lens built-in motor-driven lens (AF-I, AF-S).

Support the so-called manual lens metering refers to the manual lens mounted on the body can achieve automatic exposure, including aperture priority and program mode. This compatibility issue originated in the last century, film SLR camera F80, Nikon aperture coupling ring to the body to simplify out (the first lens compatibility castration), resulting in no parts of this costs a few dollars less than the machine can not support a manual lens (strictly speaking no built-in CPU chip manual lens) automatic metering.

In the modern digital SLR camera body, only three-digit level professional machine (D200, D300, D300S) and a number of specialized machines and D700 have the aperture coupling ring, which supports manual lens auto exposure.

Finally a new machine and nothing to do with the lens compatibility is a G lens, there is no manual aperture adjustment ring lens, the lens produced the last 10 years, these lenses are basically. These lenses in a modern and modern SLR camera body with no compatibility issues, only in the older body, such as some of the old manual camera (FM, FE series) will have on the issue can not adjust the aperture.
