The Minolta DiMAGE A1 is the latest in a family of DiMAGE electronic SLR models
that stretches back to the original DiMAGE 7, the first five-megapixel prosumer
camera, introduced over two years ago (early 2001). As you'll read below, the
new DiMAGE A1 carries on the proud tradition of the line, with a host of innovations
and improvements over the previous DiMAGE 7Hi 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.
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.
Now, Minolta improves on an already great camera model with the Dimage A1,
which boasts the same 7x lens, five-megapixel sensor, and finely-tuned exposure
control. In addition to all of the great features from the 7Hi model, the Dimage
A1 also offers 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 senses when you have the camera in-hand, to save power in the
continuous autofocus mode. It's a nice update on an already great camera. Read
on for more details.
