Read the Nikon D300
Review by Shun Cheung.

On August 23rd, Nikon announced details of a new digital SLR, the
Nikon D300. Introduced as a replacement for the
current Nikon D200, the Nikon D300 incorporates the following new
features:
- A 12.3 MP CMOS sensor
- 14-bit A/D conversion
- ISO 200-3200 (with boost to 6400)
- UDMA support for Compact Flash
- A new autofocus system with 51 AF zones
- 6fps continuous shooting (8 fps with accessory power)
- Focus tracking by color
- 100% viewfinder coverage
- A 3" LCD with 922,000 pixels
- Live View
- HDMI video output (HD)
The D300 is expected to be available in November 2007 and a street
price of $1800 is anticipated.
Here is a comparison of the Nikon D300, Nikon D200 and the Canon EOS
40D. I've included the EOS 40D because it's Canon's latest "prosumer"
DLSR, though it's $500 cheaper and probably not aimed at quite the
same market segment as the D300.

For Nikon users the D300 is clearly a step up from the D200 and an
even bigger step up from the D80 (though the D80 is a significantly
less expensive camera). There's no clear equivalent in the Canon
lineup. The new EOS 40D is perhaps the closest match, though it's $500
cheaper and so might not be expected to have quite as many
features. Above the 40D, Canon have the full frame Canon EOS 5D which
sells for around $800 more than the Nikon D300. It has fewer features,
but of course it does have a 12MP full frame sensor.
The Nikon D300 will clearly appeal to current Nikon owners of the D200
who are looking to upgrade or D80 users who are looking to move to a
more professional camera.
The Nikon Press Release
MELVILLE, N.Y. (AUGUST 23, 2007) Nikon
today introduced its most advanced DX-format digital SLR
camera, the D300.
Engineered with pro-level features and performance, the 12.3 effective
megapixel D300
combines brand new technologies with advanced features inherited from
Nikons newly
announced D3 professional digital SLR camera to offer serious
photographers remarkable
performance combined with agility.
Similar to the D3, the D300 features Nikons exclusive EXPEED
Image Processing
System that is central to driving the speed and processing power
needed for many of the
cameras new features. The D300 features a new 51-point auto
focus system with Nikons
3D Focus Tracking feature and two new LiveView shooting modes that
allow users to frame a
photograph using the cameras high-resolution LCD monitor. The
D300 shares a similar
Scene Recognition System as found in the D3 that promises to greatly
enhance the accuracy
of auto focus, auto exposure and auto white balance by recognizing the
subject or scene
being photographed and applying this information to the calculations
for the three
functions.
The D300 reacts with lightning speed, powering-up in a mere 0.13
seconds and shooting
with an imperceptible 45 millisecond shutter release lag time. The
D300 is
capable of shooting at a rapid six frames per second and can go as
fast as eight frames
per second when using the optional MB-D10 Multi-Power Battery Pack. In
continuous bursts,
the D300 can shoot up to 100 shots* at full 12.3 megapixel
resolution.
Nikons D200 digital SLR camera has been a runaway
success for us because it
embodies everything that performance-conscious photographers
demand. With the D300, weve
raised the bar with remarkable new features, greater resolution and
speed, and even higher
image quality, said Edward Fasano, general manager for
Marketing, SLR Systems
Products, at Nikon Inc. The D300 delivers
an unmatched combination of quality, performance and value thats
hard for discerning
photographers to resist.
The D300 incorporates a range of innovative technologies and
features that will
significantly improve the accuracy, control and performance
photographers can get from
their equipment. Its new Scene Recognition System advances the use of
Nikons
acclaimed 1,005-segment sensor to recognize colors and light patterns
that help the camera
determine the subject and the type of scene being photographed, before
a picture is taken.
This information is used to improve the accuracy of auto focus, auto
exposure and auto
white balance functions in the D300. For example, the camera can track
moving subjects
better and by identifying them, it can also automatically select focus
points faster and
with greater accuracy. It can also analyze highlights and more
accurately determine
exposure, as well as infer light sources to deliver more accurate
white balance detection.
The D300 incorporates Nikons new Multi-CAM 3500DX auto focus
module that features
an intelligent array of 15 cross-type sensors and 36 horizontal
sensors. These sensors can
either be used individually or in groups, with the option for Single
area AF mode and
Dynamic AF modes using groups of either nine, 21 or all 51 focus
points. The system also
features 3D tracking with automatic focus point switching that takes
advantage of all 51
AF points as it uses color and light information to accurately track
the subject. Nikon's
new Scene Recognition System and improved focus algorithms also
contribute to the
impressive performance of the new 51-point AF system.
Nikon's new Picture Control System makes it easy for users of all
experience levels to
select and apply adjustments to how their pictures are rendered and
create optimized
settings to suit their individual preferences. The same settings
produce consistent
picture tone, even when using different camera bodies. The Picture
Control System offers
four basic setting options Standard, Neutral, Vivid and
Monochrome. These can be
directly modified for easy adjustment and customization of image
parameters, such as
sharpening, tone compensation, brightness and
saturation. Photographers can customize and
store up to nine customized options in the D300 and export up to 99 to
a CF memory card,
enabling photographers to share settings among multiple cameras that
feature Picture
Control System.
Taking a cue from the popularity of Nikons D-Lighting
technology, the D300
features a new Active D-Lighting mode that, when enabled, provides
remarkable real-time
highlight and shadow correction with optimized image contrast. Active
D-Lighting produces
broader tone reproduction in both shadows and highlights by
controlling highlights and
exposure compensation while applying localized tone control technology
to achieve a more
pleasing level of contrast across the entire image. And because the
advantages of Active
D-Lighting are applied as images are captured, image editing time can
be shortened.
The D300s LiveView feature offers two modes for confirming
subjects and
composition on the new 920,000-dot, high-resolution 3-inch LCD monitor
while shooting. The
Tripod mode is designed for precise focus and accuracy when the camera
is on a stable
platform and the subject is not moving. In this mode, the camera
focuses on the subject
using focal-plane contrast and any point on the LCD screen can be
selected as the focus
point for the picture. The second mode, called Handheld mode, allows
photographers to use
the cameras conventional TTL focusing system, with all 51-points
and 15 cross-type
points available. When using this mode, the camera activates focusing
immediately when the
shutter button is pressed, to ensure accurate focus.
The D300 also employs a new self-cleaning sensor unit. Four
different resonance
frequencies vibrate the optical low pass filter in front of the image
sensor to shake
particles free and reduce the appearance of dust.
Refined Ergonomics and Usability
The D300 inherits one of Nikons most
streamlined, functional and
aesthetically pleasing layouts in a digital SLR camera, designed to
enable photographers
to take pictures with less fatigue, greater accuracy and comfort.
The cameras viewfinder provides virtually 100 percent
coverage so pictures can be
framed accurately, while an ultra-high definition 920,000 dot VGA LCD
screen on the rear
of the camera displays images with vivid color and clarity. Its
170-degree wide viewing
angle makes it easy to compose shots using the LCD screen in LiveView
mode.
The D300 features rugged magnesium alloy construction and the
cameras shutter
mechanism is tested up to 150,000 cycles. The 3.0-inch LCD is
strengthened with tempered
glass and the D300s rubber gaskets and seals protect vulnerable
entry points from
dust and moisture.
Price and Availability
The D300 will be available from Nikon Authorized
Dealers beginning
in November 2007 for an estimated selling price of $1,799.95**. With
the introduction of
the D300, Nikons current lineup of digital SLR cameras now
includes the new D3,
D2XS, D300, D200, D80, D40x and D40.
*NORMAL LARGE image setting, using a SanDisk Extreme IV
