SLR-sized image sensor
The size of the image sensor used in the DP1 camera is 20.7mm x 13.8mm. It is
approximately seven to twelve times larger than the 1/1.8inch to 1/2.5inch image
sensors used in ordinary compact digital cameras. The pixel size of the image
sensor is 7.8μm. The large photodiodes deployed at a large pixel pitch capture
pure, rich light efficiently and give the DP1 its high resolution and
richly-graduated tones.
Full-color image sensor
The DP1 uses the same 14 megapixel
（265217683 layers）direct
image sensor as the SD14. Utilizing the special features of silicon, which is
penetrated to different depths by different wavelengths of light, this direct
image sensor succeeds in full-color capture with the full RGB in a single-pixel
location. Just like film, each photodiode captures all the RGB data, so no
final-stage demosaicing is required.
Brand-new "TRUE" image processing engine
The DP1 incorporates "TRUE" (Three-layer Responsive Ultimate Engine), the
world's first image processing engine suited for Foveon three silicon embedded
layer direct image sensor. The unique image-processing algorithm, which has been
developed throughout the development of the SD9, SD10 and SD14 cameras, is
incorporated into "TRUE". It enables high-speed image processing and high image
quality.
16.6mm F4 lens designed exclusively for the DP1
The DP1 is equipped with a 16.6mm F4 lens, equivalent to 28mm on a 35mm SLR
camera, which has been designed exclusively for DP1. The large-diameter of
aspherical glass provides low distortion and high contrast images. It also
offers superior peripheral brightness. The super multi-layer coating reduces
flare and ghosting. It allows photographers to take pictures in difficult light
conditions. This lens and SLR-sized image sensor provides natural shallow
depth-of-field.
Raw format recording
The DP1 includes JPEG recording format for convenience plus a RAW data (X3F)
recording mode for retaining full image capture detail of the utmost quality.
The RAW data format provides pure data for high-resolution images, and uses
lossless compression for more compact, yet uncompromised, data files. The RAW
data format of the DP1 keeps brightness and color data in a 1:1 ratio without
relying on interpolation. Each pixel location captures the full color of RGB
data, so in RAW, X3F files, brightness and color data can be kept in a 1:1 ratio
without relying on interpolation. When the image is processed in Sigma Photo
Pro, it will preserve the balance of the natural data for the best photos with
the best image quality.
Exclusive sigma photopro software
The DP1 comes complete with SIGMA Photo Pro software, a RAW image developer that
converts all RAW data quickly and easily. Adjustments can be made in three
separate modes. The X3F Mode 3 stores the original settings of the image at the
point of capture. In the Auto Adjustment Mode, the software analyzes and
automatically makes adjustments to the RAW data. The Custom Mode allows the
photographer to make individual adjustments (exposure, contrast, shadow,
highlight, saturation, sharpness and fill-light for example). The photographer
can make changes easily and quickly by simply adjusting the slider controls
within the software. The X3F Mode stores the original settings of the image at
point of capture. Photographers' personal modifications can be saved to the RAW,
X3F file for future use. SIGMA Photo Pro supports 8-bit TIFF, 16-bit TIFF, and
JPEG file formats. The JPEG can be saved as YCbCr 4:4:4. It is also possible to
half, or double the resolution when processing the image.
Compact And Lightweight Body
The DP1 has compact dimensions of 113.3mm/4.5in. (W) x 59.5mm/2.3in. (H) x
50.3mm/2.0in. (D) and weighs just 240g/8.5ounces. Its compact body and
lightweight design makes it easy to carry everywhere.
Three Metering Modes And Five Exposure Modes
The DP1 has three metering modes, Evaluative Metering, Center Weighted Average
Metering and Spot Metering. It is also possible to select the exposure mode from
Auto, Program AE, Aperture Priority AE, Shutter Priority AE or Manual. Exposure
compensation can be set in 1/3 stop increments from +3.0 to -3.0 stops and an
auto bracketing function is also available.
Pop up (manual) built-in flash The DP1 is equipped with a pop up (manual)
built-in flash featuring guide number of 6 (ISO100 / m). It is possible to use
Normal Flash, Red-Eye Reduction Flash and Slow Synchro Mode. It also features
flash exposure compensation in 1/3 stops increments.
AF Area Selection
The AF area of the DP1 is equipped with 9 focusing points and it is possible to
manually select the desired focusing point. The focusing distance is from 50cm
to infinity, however, it is possible to shorten the minimum focusing distance to
30cm.
Manual Focus
Manual Focus is available for photographers who like to take more control, or
for use when
autofocus or focus lock is not effective. It is also possible to magnify the
display to ensure precise focusing.
Recording Movies
It is possible to record 30fps movies with QVGA (320 x 240). The digital zoom
function can be used during movie shooting. A 1GB memory card (not supplied)
allows approximately 30 minutes of movie recording.
Large 2.5" TFTColor LCD Monitor
The DP1 camera features large 2.5 inch, 230,000 pixel TFT color LCD monitor. The
LCD monitor displays 100% of the images, allowing the photographer to easily and
accurately confirm the image compensation.
Hot Shoe
The DP1 camera is equipped with a hot shoe, allowing use of the dedicated
external flashgun EF-140 DG (optional) or high performance view finder VF-11
(optional). EF-500 DG and EF-530 DG flashgun series can be used in manual mode
only.
Dedicated Lens Hood
This optional lens hood blocks out extraneous light. A hood adapter, designed to
accept a 46mm lens filter, is included.
