    Practically all DSLR cameras have CMOS sensors as they are easier and cheaper to make than the older CCD sensors. Never heard of an NMOS sensor. If they exist, they are probably an improvement over CMOS sensors. Doing some research, NMOS was invented in 1985 by Olympus but it is not as good as CMOS technology and that is why I never heard of it. CMOS won.

    In nMOS the majority charge carriers are electrons while in pMOS electrons are minority charge carriers. Complimentary logic or cMOS uses both nMOS and pMOS devices. According to the Wikipedia article, in a Digital Single-Lens Reflex camera, DSLR, the image sensor might be implemented with charge-coupled pMOS devices, CCD, or cMOS devices. cMOS has advantage of less power consumption, less components, and faster readout.
