Minolta introduces its next generation SLR-type digital camera, the
DiMAGE A1. Abstracting the best features from the DiMAGE 7 series, the
DiMAGE A1 was re-designed for today's digital photographer. With a 5
megapixel display and a 7X optical zoom, equivalent to a 28 - 200mm
35mm zoom lens, the DiMAGE offers quality and versatility in a compact,
convenient package. Offering CxProcess II, the latest image-processing
technology, this camera providing the tools to fully capture the power
of digital imaging.
The DiMAGE A1 has the world's fastest AF speed among
5-megapixel SLR-type digital cameras with a non-interchangeable 5x or
greater optical zoom.(1) Full-time AF continually focuses when the grip
sensor is activated to reduce focusing time as well as to continually
display a sharp image on the monitors.
All
cameras suffer from a slight delay between pressing the shutter-release
button and when the image is captured. Especially at long focal
lengths, this slight delay can be significant with fast moving
subjects. With continuous AF, the DiMAGE A1 uses the new 3-D Predictive
Focus Control to track the subject from the time when the
shutter-release button is pressed until the exposure is made, all while
ensuring optimal focus. This new predictive focus control continually
follows the subject through 3D space to not only provide the sharpest
images possible, but to also reduce focusing time to catch the perfect
moment.
The DiMAGE A1 is the first digital camera to employ
CxProcess II, Minolta's newest image-processing technology. CxProcess
II controls the essential image qualities of color, contrast, and
sharpness, all while minimizing noise. Brilliant, saturated color
remains vibrant without becoming unnatural or flat. Subtle contrast is
rendered to retain the richness and depth of the subject while
preserving details in the highlights and shadows. Sharpness is
controlled by balancing resolution with acutance to show fine detail
and minimze hard, unnatural edges. Dark noise can be reduced with
exposures of one second or longer with the noise-reduction menu option.
At the heart of the DiMAGE A1 is a new high-speed
image-processing LSI for increased performance. Power consumption has
also been greatly reduced.
The new Anti-shake function minimizes
the effect of camera shake, a slight blurring of the image when the
camera is handheld, to provide the sharpest image possible. The
Anti-shake system is valuable when shooting at long focal lengths or in
low-light conditions without a tripod. This allows the camera to be
handheld with exposures approximately eight times longer than usual.
When using the camera at the telephoto setting, approximately 90% of
the images recorded will be sharp with a shutter speed of 1/25s. The
Anti-shake button glows to indicate the function is active.
The
DiMAGE A1 has an incredible top shutter speed of 1/16,000 of a second.
This is not only an advantage in sport photography, but also gives
greater control over depth of field in brightly lit environs by
allowing the entire aperture range to be used. In low-light conditions,
shutter speeds up to 30 seconds can be selected as well as
thirty-second bulb exposures.
The DiMAGE A1 is built around a
high-precision, electro-optical system designed to maximize image
quality. The system starts with a 5.3 megapixel 2/3-type progressive
primary-color CCD with 5.0 million effective pixels for fine
high-resolution images. The pixel resolution of the CCD will produce
32.5 X 43.3 cm 150dpi prints or 16.3 X 21.7 cm photo-quality prints,
thereby printing sizes larger than both A3 and A5, respectively.
The
DiMAGE A1 incorporates Direct Manual Focus (DMF). DMF is found in
professional-level film cameras like the award-winning Dynax 7. After
the AF system has focused and locked on the subject, the focus can be
futher fine-tuned manually.
The DiMAGE A1 is fitted with a
1.8-inch low-temperature high-contrast color LCD monitor that can be
tilted from -20° to +90°. The monitor has an extended color, contrast,
and dynamic ranges. As the monitor has a wide-viewing angle, the camera
does not need to be held perpendicularly to clearly view the live image.
The
redesigned Digital Hyper Viewfinder gives the camera the same feel as
an SLR. It can be tilted between 0° and 90° for comfortable shooting at
low angles or in confined spaces. The viewfinder has a new precision
235,000-pixel TFT monitor, and as the viewfinder LCD is shielded, it
makes the perfect tool when working under bright light.
The
DiMAGE A1 is wrapped in a feather-light magnesium-alloy case with a
professional black finish. Completely redesigned, significantly smaller
than a compact 35mm SLR camera with a built-in flash and zoom lens,
this sophisticated imaging system can easily and slip into any bag.
Unique
to digital imaging, the DiMAGE A1's real-time histogram shows the
luminance distribution of the image before it is captured. Displayed
with the live image, the histogram allows the subject brightness and
contrast to be evaluated to optimize the camera's exposure and contrast
controls. The luminance distribution of recorded images can be checked
with a playback histogram.
