Featuring Minolta's non-extending zoom lens, which maintains the cool outward appearance of the DiMAGE X21 even when the zoom is activated, this revolutionary design uses internal folded optics, which means that the cool, slim profile of the camera doesn't have to change at all, even while recording. Even with 3x optical zoom, the camera is still just 24.5mm thick, whether carrying or shooting (21.5mm thick excluding the LCD monitor). The DiMAGE X21's 2 megapixels capture fine lines and intricate details for stunning digital images. The slow shutter speed and Dark-Noise Reduction combine to prevent graininess and give exceptional night photos with clearly contrasted dark tones.
