The Sigma DP1 14 megapixel high definition digital camera, packing the full spec. of a DSLR into the body of a compact camera The Sigma Corporation is pleased to announce the launch of the Sigma DP1 compact digital camera featuring a 14 megapixel FOVEON X3 direct image sensor (2652 × 1768 × 3 layers) as used in the Sigma SD14 digital SLR.
The DP1 is a completely new type of camera offering the full spec. and
high image quality of a DSLR in the body of a compact camera.
It is powered by the 14 megapixel Foveon X3 direct-image-sensor, which
can reproduce high definition images rich in gradation and impressive
three-dimensional detail.
It is possible to record images in RAW or the widely used JPEG in four
resolution modes. It offers five Exposure modes and three Metering
modes as well as being quipped with a built-in flash with the Guide
Number of 6, hot shoe, neck strap and 2.5 inch TFT color LCD monitor
with approx. 230,000 pixels.
The DP1 has the high resolution and functionality of an SLR, plus
adaptability in terms of accessories, all built into a small body. A
wide range of accessories, optical viewfinder [VF-11], Lens Hood
[HA-11], and Electronic Flash [EF-140 DG] are available for the DP1
camera.
Development
Sigma introduced its digital SLRs, the SD9, SD10 and SD14 to the market
in October 2002, November, 2003 and March, 2007. They have established
strong support from a wide range of photographers, both amateur and
professionals. Recently, demand for a compact digital camera with
portability as well as high image quality has increased. In order to
meet this demand, the new DP1 has been developed as a completely new
type of camera with high image quality and features that would not be
out of place in a full spec DSLR.
Main features
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 （2652×1768×3 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 (Supplied with the DP1)
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 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” TFT Color 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).
Dedicated lens hood
This optional lens hood blocks out extraneous light. A hood adapter, designed to accept a 46mm lens filter, is included.
