Produced in 1999, the Nikon F100 was Nikon's state-of-the-art prosumer / high end 35mm camera, falling just under the professional F5. The F100 was, at the time, one of the best featured cameras ever made and still remains the 135 camera of choice for film enthusiasts and many fine artists. One of the most important feature that sets aside the F100 is its complete compatibility with modern Nikon glass including G lenses that do not have a physical aperture control. It also comes equipped with a surprisingly robust auto-focus system (with five points) that is capable of accurately focusing in low light conditions and with wide-open lenses. The F100 also provides many features which are common among high-end 35mm SLR cameras, such as automatic bracketing modes, DX film speed sensing, and custom functions which allow the photographer to tailor certain aspects of the camera's operation to the way he or she works.
