New innovation and technology in Digital SLR camera
These three years has been awesome years for Digital SLR cameras. Many new innovation and technology has appeared in many new digital cameras, especially in digital SLR cameras. There are five big features that have recently emerged in digital SLR cameras that the manufacturers are using to help set their cameras apart. They are including image stabilization, dust control sensors, live view LCD screens, extended dynamic range, D-movie HD video mode.
Image Stabilization (IS)
Image stabilization is somewhat a mixed bag. It does allow one to handhold a camera with a shutter speed 2-3 stops slower then without. It also adds weight, complexity, and cost to the camera. So it’s biggest advantage is when shooting with a long telephoto indoors or in poor light outdoors. Nikon and Canon have been including stabilization systems in their lenses for years. But many of their competitors have included image stabilization (IS) in their camera bodies, providing great value to their customers. Maybe both Nikon and Canon should offer IS in both lenses and in camera bodies at ALL levels (pro, pro-am, and am). New Cameras with Image Stabilization including: Canon 450D(with kit lens), Canon 50D, Nikon D60, Nikon D90, Pentax K200D(build in), Pentax K20D, Sony DSLR-A200, Sony DSLR-A300, Sony DSLR-A350.
Live View LCD
Simply stated, Live View is the ability to frame your shot with the LCD monitor on the back of certain DSLR cameras instead of through the optical viewfinder. That is to say you can preview the photo you’re about to take using the large LCD on the back of the camera. Live View lets you see the changes in real time. That’s what “Live” View means. Considering the current market trend, it may be difficult in the near future to find a camera that does NOT have Live View.

Dust Control Sensors
Dust control digital SLR cameras prevent dust from attaching to your camera’s sensor and ruining your photos. Without a dust control system, dust can contaminate the digital sensor of your SLR camera and will be evident as little black spots in every photo you take. Dust control are common today.
Extended Dynamic Range
Extended dynamic range imaging (EDRI) is a proprietary image acquisition technique that enables quality analysis of comet images generated in the single cell gel electrophoresis assay. The EDRI technique overcomes serious limitations with respect to the range of light intensities that conventional digital image acquisition systems support. EDRI provides high dynamic range images that yield much more stable and reliable analytic results than conventional image acquisition systems can provide. Digital SLR cameras that feature “extended dynamic range” attempt to compensate for this either by limiting the brightness of highlights or by increasing the brightness of shadows to create a more balanced image.
D-movie
Nikon D90 is the world’s first D-SLR with Movie function. The D90 offers a movie function, allowing you to shoot HD720p (1,280 x 720 pixels), 640 x 424 pixels or 320 x 216 pixels movies at the professional smoothness of 24 frames per second in motion JPEG format. The D90’s sensor, which is much larger than the sensor of a typical camcorder, ensures higher image quality and exceptional low-noise, high ISO sensitivity performance, even during movie shooting. Capturing creative movie clips or the drama of life’s moving moments is further enhanced by the wide selection of incredibly sharp NIKKOR interchangeable lenses that are available, from fisheye to wide-angle to super-telephoto. And Micro NIKKOR lenses bring the magic of extreme close-up imagery to movie making.
