Nikon
D200 and Non-CPU lenses
Lenses
are some of the most desirable and expensive parts of our Nikon
photography addictions. All of us have our eye on at least one
or two more Nikkors. Wisely, Nikon has not changed their F-Mount
lens attachment bayonet for a very long time. That means your
Nikon D200 can mount,
not only the newest AF-S Nikkors and aftermarket lenses, but
also most of the older Manual Focus (MF) lenses from just a
few years ago.

Wisely,
Nikon has not changed their F-Mount lens attachment bayonet
for a very long time. That means your D200 can mount, not
only the newest AF-S Nikkors and aftermarket lenses, but also
most of the older Manual Focus (MF) lenses from just a few
years ago.
Since the Nikon D200 has a “professional” heritage, it can
do something that many other digital SLR cameras will not.
The light meter will remain functional even with older non-CPU
manual focus lenses. (non-CPU = no electronic chip in lens).
Many of the newer Nikon film and digital bodies will not allow
light metering with older MF lenses, even though they will
mount them. Instead, they disable the light meter as soon
as a non-CPU lens is mounted.
The
reason Nikon chose to do this is simple. A non-CPU lens has
no microchip inside to inform the camera body of lens settings
or distance measurements. This makes it impossible for metering
functions like 3-D Matrix metering to function, since it cannot
accurately measure the distance to the subject. Light metering
in standard Matrix, Averaging, and Spot modes could still
work on any Nikon DSLR camera so Nikon allows it in certain
cameras, including the D200.
So,
as a proud Nikon D200 owner you have a choice of all the new
Autofocus (AF) lenses on the market, and virtually all of
the older MF Nikkors and aftermarket Nikon-mount lenses.
How does one set the camera to use these older lenses? Will
you need to read dozens of manual pages to figure this out?
Happily, it is not at all complicated to set your camera for
older MF lenses. Let’s see how!
Method One – Setting Lens Specs by Using the Shooting Menu
Below,
you'll find both a quick summary and detail on how to set
the lens specs using the camera menus.
1. Open the Shooting Menu
2. Select Non-CPU lens data
3. Set the Focal Length
4. Set the Maximum Aperture
Method One Detail
Now, you'll need to set the MINIMUM Focal length, then the
MAXIMUM aperture. See Figures 1 and 2 for the steps to set
the minimum focal length. Aperture comes next.

As
in Figure 1 above, select Focal length from the menu. The
next screen will give you a series of focal length ranges.
These are 6-45, 50-180, and 200-4000 and N/A. Select the range
into which your lens best fits. (Examples: a 50mm or 135mm
lens fits best in the 50-180 selection, while a 300mm or 600mm
lens fits best in the 200-4000 selection) The N/A setting
is used with specialty lenses that need no focal length setting.
Special Note: For more detail see your D200
manual on pages 93-95. For a list of compatible Nikkor lenses
see manual pages 174 and 175.
If
you are using a zoom lens, there is no difference in the setup.
Simply enter the minimum focal length, and there should be
good results across the entire zoom range. For example, an
80-200mm zoom would go in the 50-180 range, since the MINIMUM
focal length is the important number.

In
Figure 2 above, we see how to set the Maximum aperture. The
selections run from f/1.2 to f/22, with an N/A selection for
specialty lenses with no aperture settings. Look at your lens,
see what the largest aperture is, and set it in the menu.
For instance, my AI-S Nikkor 50mm has an f/1.8 maximum aperture.
If there is no exact match, use the one closest to your lens'
actual maximum aperture.
Once
again, with a zoom lens, just enter the maximum aperture as
you would on a prime lens. As long as the zoom is not a variable
aperture zoom (and most pro lenses aren't) you'll be fine.
Variable aperture zooms are discussed in the Variable Aperture
Zoom Adjustment section at the end of this article.
The
Nikon D200 will take the maximum aperture menu setting and
detect the position of its aperture ring to know what aperture
is in use. As you turn the aperture dial on the lens the Nikon
D200 will adjust the meter accordingly.
Special
note: Remember that we are only concerned with the MAXIMUM
aperture and MINIMUM focal length settings
in-camera.
