10.8 Megapixel, 2.5 in. LCD Screen, Weight: 2.09 lb.
The Sony α (alpha) DSLR-A100 camera is an instant classic: the top-quality 10 mexapixel DSLR system camera that builds on a two-decade legacy of Minolta photographic leadership, accepts 20 years of A-mount lenses sold worldwide—and introduces Sony imaging innovations like high-sensitivity shooting with Super SteadyShot® in-camera image stabilization, Dynamic Range Optimizer to automatically increase detail in bright and dark picture areas, new anti-dust technology to keep the CCD imager clean for better pictures and Eye-Start ® autofocus system for faster camera response.
A great combination of new features and the usual Nikon image and build quality make this a superb camera.
The Olympus PEN E-P1 may look like a throwback to retro photography, but it’s expensive and flawed. However, it's beautiful image quality renders almost impossible to dislike.
The A330 is a competent, fully featured and easy to use DSLR, but a backward step in some respects.
