Although the name D100 suggested that it was a digital version of the Nikon F100, the camera design more closely resembles the Nikon F80 (also known as Nikon N80 in U.S.), which is a much more consumer-oriented camera than the professional F100. The price of the camera dropped over time to $1699 in May 2003, and $1499 in December 2003. In the Spring of 2004 Nikon released the D70, which offered similar features to the D100 at a lower price of $999. However, Nikon continued to produce the D100 until 2005 when a more advanced and professional-oriented successor, the Nikon D200, was released.

(Early v1.x firmware supported FAT16 only, so without the firmware upgrade the D100 will only be able to use or "see" 2 GB of available memory on larger cards.)
