The DiMAGE Z1 is the first in an innovative series of Minolta's new user-friendly,
powerful SLR-type digital cameras. Its 10X Mega zoom, equivalent to 38-380mm 35mm camera zoom,
in combination with the digital zoom, offers a 40X zoom range. The DiMAGE Z1 comes complete
with a 3.2 megapixel display and weighs in at only 305g. With Minolta's new drive mode, Rapid
AF, and minimal shutter release lag time, this compact, stylish digital camera has all the
necessary imaging tools to capture high-quality digital images.
The 10X Mega-zoom is a fast f2.8 - f3.5 lens allowing fast shutter speeds for sport or natural-light
photography. The ten-element, seven-group design employs two aspheric lenses to minimise aberrations
and produce sharp images.
Such powerful optics combined with a high-resolution 3.3 megapixel
1/2.7 interline primary colour CCD require a powerful auto-focus system. The DiMAGE Z1 employs Rapid
AF to ensure sharp images with minimum delay. Rapid AF utilises a passive AF sensor that instantly
estimates the distance between the subject and the camera's CCD to determine the precise focus point.
A high-speed drive focuses the lens quickly and smoothly, while the CCD uses a 60fps sampling rate to
determine the optimum focus. This sampling speed is twice the rate of most digital cameras on the
market today. All this translates into a 0.3 second focusing time at a focal length of 5.8mm and 0.4
seconds at 59mm, giving the DiMAGE Z1 the world's fastest AF among digital cameras with a built-in 10X
or greater optical zoom.1
Minolta's new drive mode, Progressive Capture, ensures a moment will
never be missed. When the shutter-release button is pressed and held, Progressive Capture begins saving
images in the buffer memory. Watch the action on the monitor and when it is over, release the shutter
button to save the images from the buffer memory to the memory card. Six frames are saved when using
standard continuous advance, and 10 frames when using Ultra High Speed (UHS) continuous advance.
Standard continuous advance records at approximately 1.5 fps at any image size or quality setting.
UHS continuous advance records 1.2 megapixel images at 10 fps.
The affect of camera shake, a
slight blurring of the image when the camera is handheld, can be a significant problem when such
powerful optics are used. Minolta engineers have developed an advanced program exposure line to
maximise shutter speeds by controlling the aperture and camera sensitivity based on the selected
subject program and focal length.
Every aspect of the DiMAGE Z1's performance is breaking
records in speed. Start-up time is only 2 seconds and shutdown time is just 2.4 seconds. After
focus has been locked, the shutter-release time lag is 0.06 seconds or less, comparable to an SLR
film camera. The camera will be ready to capture another image in 1.2 seconds or less after the
exposure.
The DiMAGE Z1 packs Minolta's most powerful flash in a digital camera yet. With
a guide number of 12 meters (39 in feet), the flash can illuminate a subject up to approximately
6m away (20 ft.) when used at the wide-angle position with autoexposure and auto camera sensitivity.
The DiMAGE Z1 is compatible with the Minolta Program Flash 3600HS (D) or 5600HS (D) units as well
as the latest addition to the line, the Program Flash 2500 (D). These powerful flash units can be used
directly on the camera. The 3600HS (D) and 5600HS (D) have zoom heads that automatically adjust as the
camera's lens is zoomed in and out, and their heads can be tilted for bounce illumination. The 5600HS
(D)'s head also swivels and the flash output can be controlled with power ratios. The newest addition
to Minolta's Program Flash line, the new 2500 (D) is a compact, automatic flash unit with a tilting
head and an affordable price tag.
The DiMAGE Z1 is not limited to capturing static images, but
high-quality VGA (640 X 480) movies can be recorded at 30fps. Image size and frame rate can be selected
to balance image quality with file size. Three image sizes are available: 640 X 480, 320 X 240, and 160
X 120. Because of the high frame rate of the CCD, movies may be shot at 30fps to create natural
flicker-free images, or 15fps to maximise recording time. The length of the movie is limited only
by the memory card capacity, image size, and frame rate.
Because the DiMAGE Z1 can capture
large, high-quality VGA (640 X 480) movies, image sharpness and brightness are absolutely critical.
During recording the Z1 will continue to auto-focus to provide the sharpest possible image, and the
night-movie mode can make colour recordings under extreme low-light conditions.
The controls
and dials are laid out for clear, intuitive operation. For quick changes to camera settings, the
large exposure mode dial and zoom lever are located on the top of the grip. Placed on the back of
the camera, the controller is a straightforward five-way array used to control many of the camera's
advanced features and menus. The large grip provides the DiMAGE Z1 with secure, comfortable handling,
especially for keeping a steady hand in low-light conditions or when using long focal lengths.
Ordinary AA batteries power the DiMAGE Z1, and ubiquitous alkaline or rechargeable Ni-MH can also
be used.
CxProcess II, Minolta's new image-processing technology, is integrated to bring out
the best in the 3.3 megapixel 1/2.7 interline primary-colour CCD. CxProcess II controls the essential
image qualities of colour, contrast, and sharpness while minimising noise. Brilliant, saturated colour
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. Balancing resolution
with acutance controls sharpness, as well as shows fine detail while minimising hard, unnatural
edges.
The DiMAGE Z1 possesses the necessary, advanced technology and powerful optics enabling
the capture of high-quality images and 30fps VGA movies. This compact, stylish digital camera has the
imaging tools required to capture first-rate images in virtually any situation.
