Features
The F4 introduced many Nikon owners to autofocus (as well as focus tracking), and was the first professional Nikon to utilize a vertical-travel metal-blade shutter (with shutter balancer to minimize noise and camera bounce). As a fully electronic camera with motorized film transport (up to 5.7 frames per second), it required one of three available bottom-mounted battery packs to operate, using standard AA or rechargeable cells. For the first time on a Nikon SLR, two of those battery packs also offered an additional vertical shutter release button and grip for using the camera vertically.
Its controls were transitional between those of mechanical SLRs and future professional film and digital SLRs: the F4's electronics, LCD viewfinder display, autofocus, programmed auto-exposure, and matrix meter looked to the future, but it also retained classic dedicated analog dials for shutter speed, lens aperture, metering pattern, and exposure compensation.
The F4 was the first Nikon F-series camera to lack a manual film-advance lever, though it offered both motor-driven and manual film rewinding. Like previous F-series cameras, the F4 featured a high degree of customization to specific tasks, with various remote controls, film backs, and viewfinders available. While it was a complex camera with over 1700 parts, the F4's high-quality mechanical and electronic components, as well as weather sealing and tough construction, made for a reliable and long-lived professional SLR.

Famous quotes containing the word features:
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
“All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!”
—Herman Melville (1819–1891)
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
