Photographer Rob Galbraith, certified sensor sleuth, reports on his website that Nikon has indeed admitted that the new D3x is using an image sensor made by Sony.
So is it the same sensor used in the Sony Alpha 900 DSLR? Well, yesâ€¦ and no. Nikon says the sensor was specifically developed for the D3x.
The statement from Nikon:
â€œThe Nikon D3Xâ€™s 24.5-megapixel FX-format (35.9 x 24.0mm) CMOS sensor was developed expressly for the D3X in accordance with Nikonâ€™s stringent engineering requirements and performance standards, with final production executed by Sony. Featuring refined low-noise characteristics, 12 and 14 bit output, Live View capability and more, the D3Xâ€™s unique sensor design was carefully blueprinted to perform in perfect concert with proprietary Nikon technologies including EXPEED Image Processing and the Scene Recognition System. Meticulous efforts allowed the sensor to become one of the many essential components and technologies which contribute to the D3Xâ€™s superior image fidelity.â€
