Mobile Photography: Which smartphone has the best HD image and HD video recording camera hands down?

Nokia Lumia 1020. 41 megapixels. Reinvented zoom. Nothing else comes close. 41 megapixel giant 2/3" BSI sensor with http://en.wikipedia.org/wiki/Optical_image_stabilization (OIS), that uses a pixel oversampling technique that reduces an image taken at full resolution into a lower resolution picture, thus achieving higher definition and light sensitivity, and enables lossless zoom. PureView Pro is an imaging technology used in the Nokia 1020 device. It is the combination of a 1/1.5" large, very high resolution 41 mpx image sensor with high performance Carl Zeiss optics. The large sensor enables pixel oversampling, which means the combination of many sensor pixels into one image pixel. PureView imaging technology delivers high image quality, lossless zoom, and improved low light performance (see below). Behind the lens of a 41MP Nokia Lumia 1020 It dispenses with the usual scaling/interpolation model of digital zoom used in virtually all smartphones, as well as optical zoom used in most digital cameras, where a series of lens elements moves back and forth to vary the magnification and field of view. In both video and stills, this technique provides greater zoom levels as the output picture size reduces, enabling 4x lossless zoom in full HD 1080p video, 6x lossless zoom for 720p HD. Optical image stabilization is also present to nullify shaking of hands when taking a photo and to allow significantly more light to enter the sensor for better low light photos. It also has a shutter speed of 1/16,000 s. The Lumia 1020 ships with Nokia's new Pro Camera application, allowing a great degree of control over the camera settings. Providing "swipe-able" dials in a concentric ring display, settings such as exposure level, white balance, shutter speed and film ISO can be adjusted "on the fly" to enable changes to be visualised before a shot is taken.
