The new Nikon D3x was officially announced this morning. It’s basically a D3 body with a brand new sensor, giving it an effective 24.5 megapixels, and this silicon makes it the highest resolution camera in the Nikon lineup. With a total of three FX cameras (Nikon D3, D700 and now the Nikon D3x) Nikon offers a serious line of FX-based DSLR cameras for the professional user. Add to that the Nikon D300 DX-sensored camera, and you are looking at four pro cameras with excellent build, high dynamic range, extremely fast speed, and amazing low light ISO handling!
