The Konica Minolta DiMAGE A2 is the latest in a family of DiMAGE electronic
SLR-style models that stretches back to the original DiMAGE 7, the first five-megapixel
prosumer camera, introduced over three years ago (early 2001). As you'll read
below, the new DiMAGE A2 carries on the proud tradition of the line, with a
host of innovations and improvements over the previous DiMAGE A1 flagship model.
In 2001, Minolta shook up the high end of the prosumer market, by beating everyone
else to the punch with the first five-megapixel prosumer digital camera. And
it wasn't just "any" five-megapixel model either, but the DiMAGE 7,
an electronic SLR design with a remarkably high quality 7x optical zoom lens,
a host of advanced image-control functions, and an all-new electronic viewfinder
using ferroelectric LCD technology for impressive low light performance. Alongside
the DiMAGE 7, Minolta offered the lower resolution (3 megapixel) DiMAGE 5, which
was similar in most functions except those related to the differing sensor choice.
In 2002, Minolta upped the ante again first with the DiMAGE 7i, which added
numerous features, and offered dramatically improved focusing speed and shutter
response. They also announced the DiMAGE 7Hi, which added an external flash
sync socket, higher-speed continuous shooting for full-resolution files, and
an extra-fine JPEG image-quality setting. The DiMAGE 7 was an impressive camera
when it was introduced, and Minolta's improvements implemented in the 7i version
were well-considered, intelligent, and bountiful. With the 7Hi, they brought
the camera fully into the photo studio, with the external flash sync connector,
in addition to increasing continuous-mode speed, and offering an extra-fine
JPEG mode as an alternative to TIFF or RAW files. Finally, the DiMAGE 7Hi offered
several options for color space, including both normal and "vivid"
sRGB options, and Adobe RGB.
In 2003 , Minolta updated the line once again with the DiMAGE A1, which added
14-bit A/D conversion, a tilting LCD monitor, blazingly fast 1/16,000 second
maximum shutter speed, tracking autofocus, and a grip sensor that actually sensed
when you had the camera in-hand, to save power in the continuous autofocus mode.
In late 2003, Minolta Co. Ltd. merged with Konica Corp., creating the new Konica
Minolta brand name, under which subsequent models will be sold.
Now, Konica Minolta improves on an already great camera model with the DiMAGE
A2, which boasts the same 7x lens, tilting LCD, and grip sensor, exposure control,
and tracking AF as its predecessor. In addition to all of the great features
from the A1 model, there are quite a few important updates. The DiMAGE A2 offers
a higher-resolution eight megapixel sensor yielding images up to 3,264 x 2,448
pixels. There's also a new electronic viewfinder which can either provide a
whopping 640 x 480 pixels of resolution, or trade half of that resolution off
for an impressive 60 frames per second refresh rate at 640 x 240 pixels. Autofocusing
on the A2 also gets another update, with a faster 3D autofocusing algorithm
that offer dramatically improved focusing speeds and better focus tracking.
Given the larger maximum image size, an update to high-speed USB 2.0 connectivity
is another welcome addition. Other changes include an improved 544 x 408 pixel
movie mode at 30 frames per second up to the memory card's capacity, a new 3:2
aspect ratio setting that gives 35mm film proportions, and a new depth-of-field
preview function. All in all, the A2 amounts to a pretty robust update on an
already great camera. Read on for more details.
