Nikon D100

The Nikon D100 is a discontinued 6-megapixel digital single-lens reflex camera made by Nikon Corporation and designed as a consumer alternative to the professional D1 series cameras. It was the precursor of both the more advanced D70 and D200 cameras with the former continuing the consumer offerings and the latter beginning an advanced consumer and professional lineup. The D70 kept the controls which the D100 inherited from the F80 film camera, which has evolved into the current D7500 and D750 offerings, in cropped frame and full frame respectively. The D200 adopted the controls of the D1 series.

History and Design
It was introduced on February 21, 2002 at the Photo Marketing Association Annual Convention and Trade Show as a direct competitor to the Canon EOS D60. With a price of US$1,999 for the body only in the United States, it was the second 6-megapixel DSLR to break the $2000 barrier, after the EOS D60.

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 the United States), 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 superior 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.
