Nikon's professional workhorse digital SLR camera gets more than a single-digit upgrade to its model number in the new D4. Though encased in a body of similar size and shape to its predecessors, the Nikon D4 now uses a 16.2-megapixel full-frame CMOS sensor backed up by a new EXPEED 3 image processor. Nikon expects the combination to deliver very high dynamic range and low noise across a wide range of ISO settings.
Also known as Rebel T3 in the United States, the EOS 1100D is designed for those who are new into professional photography. It is, by far, the most affordable among the EOS DSLR models of Canon. It has a 12mp APS-C sensor that’s capable of capturing respectable images. Professional Digital Camera Reviews from ep
Canon also produces a professional digital video camera called the Canon XH A1. As soon as you open the box you'll fall in love with it. The camera itself is really substantial and has tons of manual controls, so that you don't have to go thru menus to change parameters. The layout of everything is great. The dual on/off and zoom controls are just very convenient as well.
