The Sony Alpha 100 is a compact and relatively lightweight 10-megapixel D-SLR that is based 
around the Konica Minolta core technologies of a CCD-shift Anti Shake system and the Dynax lens mount. They have been adopted by Sony with the former now called Super Steady Shot.
The Dynax mount (called Maxxum in the US) means the Alpha will benefit from over 16-million lenses already out there and in use, plus a host of new optics ready for launch and the promise of 21 new lenses by the end of this year. Add to that a large collection of other accessories that have been moved across from the KM brand and tweaked for use on the new Alpha 100 and the offering is certainly substantial.
The Alpha 100 offers an almost retro approach to control with the shutter release and setting shift dial plus the drive mode button being accompanied by two large mode dials one either side of the pentaprism viewfinder housing; one, on the right, offers the "usual" array of scene modes including the Program, Auto, Aperture and Shutter priority and the full manual control option, while the other, on the left, provides fast access to some of the cameras more powerful options.
