SIGMA SD15 technology
X3 Direct Image Sensor
14 Megapixel Foveon X3
direct image sensor
The Foveon X3® direct image sensor
captures all primary RGB colors
at each and every pixel location.
As the photo detectors are arranged in
three layers, full and complete color is
captured giving the images
a three-dimensional feel.
Focal Plane Shutter
Durable focal plane shutter
The durable focal plane shutter
mechanism has a life cycle of over
100,000 exposures and dramatically
reduces the amount of dust and dirt
from the shutter mechanism.
The photographer can enjoy taking
pictures without worrying about dust
and dirt adhering to the image sensor
either from inside or outside the camera.
Two motor systems
Prevention of camera shake
The two motor systems are driven by
the mirror-drive and shutter charge
which lowers the vibration of the mirror
movement, preventing camera shake.
The mirror lock-up mechanism raises the
mirror, preventing further vibration when
the shutter is released. The prevention
of camera shake is especially effective
for macro photography and when using
ultra-telephoto lenses.
Improved buffer memory
21 frames can be captured
continuously in RAW mode
The SD15 is equipped with DDR II
buffer memory which is twice as large
in capacity as the SD14's buffer. The
camera's high-speed image processing
circuits are capable of handling the
large data files generated by the high-
resolution 14 megapixel sensor. The
SD15 features a continuous shooting
speed of 3 frames per second with up
to 21 RAW Images that can be captured
in continuous shooting mode.
TRUE II
TRUE II image processing engine
The SD15 incorporates the TRUE
(Three-
layer Responsive Ultimate Engine)
II" image
processing engine which improves the
processing speed and overall image
quality. The unique image-processing
algorithm provides high resolution
power and reproduces high definition
images with richly graduated tones.
The improved processing speed of
RAW and JPEG data provides ease
of camera operation.
SD card
Unifying memory cards
for added convenience
The SD15 adopts the SD card
(compatible with SDHC)
which is also
used in the DP series of Sigma cameras
improving convenience to users
of both camera systems.
AFE(Analog Front End)
Improving performance
at high sensitivity
AFE
(Analog Front End)
converts the
color data, which full-color capture
systems record, to a digital signal. This
enables the camera to reproduce high
definition and richly colored images.
ISO50 - 3200
Providing noiseless image processing
The SD15 captures light effectively
and ensures noiseless image processing.
The image sensor provides high
definition with rich, gradated tones.
5-point AF
Fast and precise focusing
with 5-point AF
The auto focus sensor features
5 focusing points (center, left, right, up
and down) ensuring consistently fast
and precise focusing. The AF metering
features a cross type sensor in the
center of the screen. Selecting the
AF point can be done manually or
automatically.
Improved Auto Bracketing function
Five frame Auto Bracketing function
In addition to the usual three
frame bracketing, five frame
bracketing has now been added to
the Auto Bracketing function.
It allows users to get a more detailed
and accurate exposure.
Wide coverage viewfinder
Bright viewfinder image by
the incorporation of a pentaprism
The SD15 features a pentaprism
viewfinder with 98% (vertical
and horizontal) coverage, 0.9x
magnification and an 18mm eye
point. A diopter adjustment is also
equipped which can be adjusted
from -3 to +1.5 dpt.
Exposure compensation function
More control of image exposure
It is possible to adjust the camera's
measured exposure value. When
it is difficult to determine the
exposure setting due to variable
light conditions, it is possible to
take a sequence of pictures of the
18
