Sony Alpha DSLR-A100 June 20th, 2006 | by David Elrich

Features and Design

Long-time observers of the digicam scene will quickly notice the Sony DSLR-A100 closely resembles the earlier Konica Minolta Maxxum 5D and 7D. That's because when KM left the camera business it sold its assets to Sony. Sony took this framework and completely reworked the electronics. Whereas the Maxxum 5D/7D maxed out at 6.1MP imagers, the Sony uses a 10.2-megapixel CCD that it manufactures. The Nikon D200 ($1,699) is the only other D-SLR with a 10.2MP imager and—in case you're wondering—it is a Sony chip powering the camera. To its credit, the D200 takes a full five frames per second (fps) burst compared to a maximum of three for the Sony. This higher speed and the required enhancements to the shutter mechanism is one of the reasons you'll pay $700 more for the Nikon. You're also paying for the Nikon name, too.

The Sony D-SLR has a number of other features worth noting. One of the most important is Super SteadyShot, the company's name for image stabilization. In this case, it uses a Konica Minolta-developed CCD shift system that adjusts the imager to counter hand shake. Now you can take extreme telephoto shots or ones in low light with much less risk of blur. This also allows from two to 3-1/2 stops of latitude in exposure for hand-held shooting at longer shutter speeds than would otherwise be possible. In the end, you have more opportunities to shoot in natural lighting without a tripod or a flash. This feature turns every lens you use into an image stabilized lens, saving loads of money since IS lenses cost a pretty penny. The DSLR-A100 has a top ISO of 1600 to help shoot with available light.

The camera also has an anti-dust system that prevents specks of dust from landing on the CCD and ruining your images. Since dust can get inside the camera every time you change lenses, this can be real life—and money--saver. It works automatically each time you turn off the camera.

Since the alpha is based on a Konica Minolta framework it has a KM bayonet mount. This is good news for the vast majority of owners of Konica Minolta lenses since Sony says almost all of those made since 1985 will work with the camera. Sony plans to introduce 19 lenses under its own name soon after the main introduction date. Sony admits many of these lenses are newly made Maxxum glass with simple cosmetic changes. The company is also working with its long-time partner Carl Zeiss to create three completely new lenses including an ultra-wide, 16-80mm Vario-Sonnar T* zoom and two fixed focal length telephoto models--a Planar T* 85mm and Sonnar T* 135 mm. We primarily used the new kit lens as well as many other older Maxxum lenses including a 16mm lens that functioned as a 24mm thanks to the 1.5x digital factor.
