First Exposure: Nikon D1
By John Rettie
Its not often that a new camera comes along that generates so much
interest. The Nikon D1, which was first disclosed one year ago, is just
such a camera. Although Nikon showed a wooden mockup of the camera at
the PMA show in February 1999 it did not reveal any details except to
say that it would be a significantly cheaper than the closest cameras
already on the mar-ket. At the time the closest compa-rable camera was
the Kodak DCS 620, which cost around $16,000. Industry pundits reckoned
Nikon would probably introduce the D1 at about $7000 price point.
Finally in June Nikon unveiled pro-totypes of the D1 and announced that
the retail price would be $5580 when the camera went on sale in the fall.
Needless to say, this aggres-sive price was greeted with praise from digital
camera fans and skepti-cism by Nikons competitors. All that remained
now was for users to get their hands on actually produc-tion cameras.
Nikon started shipping the D1 in October although supplies were naturally
constrained at first as buyers around the world grabbed the cameras as
soon as they hit the dealers shelves. Within hours mes-sage boards
on the numerous digital photography web sites around the world were full
of users reports. Most praised the camera while a few criticized
it, saying the quality of the images was not as good as those produced
by the much more expen-sive Kodak cameras. Gradually though, as more and
more profes-sional photojournalists and sports photographers in particular
have got their hands on the cameras the praises are beginning to far out-weigh
the naysayers.
Anyone who has used a Nikon F100 will immediately feel at home with the
D1 as it feels much the same. The magnesium body is cov-ered in the usual
black finish with the trademark red pad on the hand-grip. There are the
two thumbwheel controls in front of and behind the shutter release for
controlling aper-ture and shutter speeds. Theres the four-way toggle
switch on the back for adjusting the focus points and for scrolling through
various menu options used for camera settings. There are two small LCD
screens on top and on the battery compartment for displaying information.
In fact, the only significant external differ-ence on the D1 that sets
it apart from the F100 is the large color LCD screen on the camera back.
Its not until you see this that there is any clue that this is not
just an ordinary 35mm film camera. This screen is of course the viewing
screen that al-lows one to review images after they have been captured
and to view the various menu options.
Its important to remember that a digital camera is in effect a regular
camera, used to capture images, and also a film processor used to process
and store the images after they have been captured. For this reason it
is appropriate to look at the two as-pects of the D1 separately.
First, The Camera
The D1 has all the attributes one has come to expect in a current pro-fessional
Nikon camera. It has 3D-matrix image exposure control using a 1005-pixel
RGB exposure color me-tering system, which is the same as the system found
in the F5. Metering can be full matrix, center-weighted or spot. The D1
has the same autofocusing sensor module as the F5 and F100 with five AF
sensors, allowing for a choice of five focusing positions. Autofocusing
can be achieved in single or contin-uous servo or manual. Focus track-ing
is automatically activated when the subject starts to move. Of course,
all these functions only work with the newest D-series Nikon lenses, but
as always the camera will accept just about every F-mount Nikkor lens
ever made.
One area where the D1 differs from the F100 is in its shutter. It has
a charge-coupled electronic shutter which gives it a shutter speed range
from 30 seconds to 1/16,000. Whats more it has a flash sync speed
of 1/500. Being a digital camera it does not have a motor drive but it
can shoot at 4.5 frames per second for up to 21 shots. Its shutter lag
time is 0.058 seconds. The unique-to-the-D1 NiMH battery pack fits in
the bottom of the cam-era and powers all functions on the camera.
The evaluation camera we tried included the new 1735mm f/2.8 zoom
lens and the SB-28DX flash-gun. Both of these items have been introduced
in conjunction with the D1s release as they work well to-gether.
The flash is an upgraded version of the popular SB-28 and has different
circuitry to provide cor-rect exposures with a digital camera as the TTL
reading is taken off a gray curtain behind the mirror just in front of
the CCD instead of from the film in a regular camera. The flash stills
works correctly with a regular film camera. Because the ef-fective length
of a lens is different in the D1 compared to a 35mm cam-era, the 1735mm
zoom becomes a 25.552.5mm zoom lens, making it an ideal everyday
lens for photo-journalists and many others.
Overall this combination of cam-era, lens and flash worked well. At no
time did we feel the camera was any different in operation from a regular
film camera. In fact, the ma-jor difference was that we did not have to
worry about changing film. On one occasion we shot 400 pic-tures without
having to add a stor-age card or even change batteries. It was like shooting
a camera with a continuous roll of film.
Next, The Processing Side Of The Camera
When you analyze the differences between various film cameras there is
not a lot to choose between the end resultsa good camera with a
good lens will produce a good pic-ture. The more important variables are
the film and lens. Sure there are differences between the ease of use,
speed of operation, the robustness of the camera body and the ability
to operate in adverse conditions. With a digital camera though the most
important part of the final re-sultthe imageis a function
of the camera. The critical part of the camera is the CCD chip and the
electronics built into the camera. Its this that differentiates
the good from the barely adequate.
Ideally a digital camera should be no different to use than a film cam-era.
Its operation should be trans-parent during the picture taking stage.
After the picture is taken the fun begins. The information cap-tured in
a traditional camera is stored on the film and it is not available for
viewing until the film is processed. The film also acts as the storage
mechanism, processing and storage are fulfilled at the same time.
On a digital camera the informa-tion is captured instantly on the CCD.
It then needs to be stored immediately. The processing can be done straight
away or it can be done later. In effect, the process works in the opposite
way from a film cam-era. Storage is the critical issue im-mediately after
the picture is cap-tured.
This has been the Achilles heel of most digital cameras. Studio cam-eras
tethered to a powerful com-puter offload the information to the computer
for storing and processing. But obviously out in the field this is impossible
so the computer has to be part of the camera.
On all these fronts the D1 sets new standards. For starters, as men-tioned
before, it can capture up to 4.5 frames per second on continu-ous mode
for a burst of 21 frames. It then takes several seconds for the camera
to transfer those from the internal memory buffer onto the storage card
but as they are loaded, more pictures can be captured at a slower rate.
Obviously, in most cases it is unlikely that one would need to shoot much
faster. After all even a film cameras buffer fills up
after 36 exposures!
The D1 has one Compact Flash (CF) Type I/II slot for holding a Compact
Flash storage card or the new IBM microdrive. During the short time we
had the camera we got to try a 96MB CF card and a 340 MB microdrive. Although
Nikon has not yet officially approved the usage of the microdrive because
of con-cerns about heat and usage in areas with high humidity, the reality
is that the drive works very well in al-most all circumstancesit
certainly worked well for us. We shot 400 pic-tures at Fine and Normal
settings and only filled about 300 MB of the 340 MB on the card. It was
great not having to load film 11 times during the shoot! And not once
was the camera not ready for the all-impor-tant shot.
It should be noted that at the highest Raw level image quality,
the camera can only shoot 10 im-ages in one burst as each image is about
5Mb in size. These images also have to be processed by the Nikon software
on a computer whereas the images saved at the other settings are standard
JPEG files that can be read by any soft-ware immediately.
Although the D1 comes with a Firewire cable connection, we never actually
connected it during our re-view period as it is so much easier to just
take the storage card out and place it in a card reader connected to the
computer. The transfer is easier and faster and avoids having to turn
the camera on. In a studio however the camera can be tethered via the
Firewire cable and operated remotely with the optional Nikon Capture software.
An important part of image cap-turing on a digital camera is adjust-ing
the white balance. Most digital cameras read the information at the camera
body using an external white balance sensor. In the D1 the white balance
is captured by the me-tering sensor, which means it is measuring the white
balance of the subject as seen through the lens. This is significant as
it allows a more accurate reading as the cam-era and subject can be in
two differ-ent lighting conditions such as shade and sunlight. In addition
the white balance can also be adjusted to variety of conditions such as
flu-orescent, flash, cloud, sunlight or shade. One can also manually ad-just
the color balance to make an image warmer or cooler in the same way the
EV value is adjusted in steps. This proved useful, just like having a
built in set of warming fil-ters.
There are numerous other features on the D1 that help it produce excel-lent
images including a low-pass fil-ter just in front of the CCD to pre-vent
color aliasing. An infrared ray reduction filter is also included to eliminate
the effects of infrared rays.
Because the camera is a SLR it is not possible to preview an image be-fore
the picture is taken. However it can be reviewed immediately after capture
on the 2-inch color LCD screen on the back of the camera. Each image captured
can be re-played rapidly and it is possible to see a histogram of an image
along with pertinent detail such as shutter speed, aperture settings along
with the JPEG compression level. Once one has experienced this instant
feedback capability of digital cam-eras it is very disconcerting to have
to go back to using a film camera and have to wait until the film has
been processed to see exactly what images have been captured.
Youll notice that we have not yet mentioned the CCD. This is of
course the most important part of the D1. Its a 23.7x15.6mm 2.74-megapixel
chip that produces a 2012x1324-pixel image. Although it only has slightly
more pixels than the Nikon Coolpix 950 (1600x1200) its physical size is
about 15 times greater because each pixel is about nine times larger in
area. According to Nikon, this allows each pixel to capture more light
with a wider dy-namic range. The cameras com-puter processes the
image to pro-duce a less grainy image than that ob-tained by high-speed
film according to Nikon. At the normal setting the speed of
the CCD is equivalent to 200 ISO. It can also be adjusted up to 1600 ISO
with a matching gain in noise.
Whats the quality of the image like? Thats the whole crux
of the matter, of course. Pretty impressive at first. It is very difficult
to show what the images look like in a mag-azine. In reality it would
be almost impossible to differentiate an image captured on the D1 from
one cap-tured on a F100. We printed up an image of a model taken on slide
film and compared it to a similar image shot at the same time on the D1.
An 8x10 and an 11x14 were printed on an Epson Photo EX ink jet printer
which is actually a two-year old printer so is not even the best that
can be done. The digital 8x10 is sharper than the photographic 8x10 (machine)
print and there is definitely more detail in the models hair. On
the 11x14 print one can begin to see clumping in areas if one holds the
print about six inches from ones eyes. At normal viewing distances
the 11x14 digital image looks just fine. In big enlargements there is
still a slight problem of pix-elization along angled hard edges such as
on a car body or patterns on clothing. However, at smaller sizes there
is no discernible difference from a traditional photographic print. Color
reproduction was accu-rate in our tests. The tone of images as well as
the white balance can be changed on the camera so that color balance can
be adjusted in different ways. Then in most cases colors can be adjusted
easily after images have been transferred to a computer.
Perhaps the best demonstration of the D1s capability is that one
was used to capture the impressive dou-ble page picture of the defining
mo-ment in Super Bowl XXXIV, which was published in Sports Illustrated.
This illustrates that the D1 is a camera that can absolutely compete with
a high performance 35mm film camerain fact it is more efficient
as one does not have to change film after every 36 exposures. For sports
photographers shooting a burst of 21 shots is a no brainier and there
is less worry about missing a shot while changing a roll of film or even
of having to be concerned about using up too much film.
Theres no doubt that the Nikon D1 is the shape of things to come.
It is the first SLR-type digital camera built from the ground up as a
digital camera, rather than being a modi-fied film camera, that is fully
com-parable in operation to a high-end 35mm camera. Because of this it
will undoubtedly earn its place in the photography hall of fame
just as the Nikon F did some four decades ago.
