Nikkor and the AF-200mm f/3.5 Nikkor. It was the first autofocus camera to be produced by Nikon, in 1983. However, even while the more successful subsequent Nikon AF design for the F4 and other models put the focus motor in the camera body, the F3AF's in-lens approach foreshadowed in-lens autofocus designs that would later come to dominate the market more than 15 years in the future, such as Canon's USM and Nikon's own Silent Wave Motor (SWM) lenses. Construction Nikon abandoned the earlier mechanically operated shutter of the F2 for a modern, electronically controlled, horizontally traveled metal curtain design. The new shutter proved to be equally reliable and less maintenance-intensive overall, though the decision to retain the horizontal-travel design significantly limited its top flash sync speed (1/80 sec.) compared to other Nikons, some of which used the Copal shutter. This decision forced many disappointed press photographers to use Nikon's semi-pro bodies (FM, FE, FM2, FE2, etc.) instead when higher sync speeds were needed, usually for fill flash in daylight situations. The F4 finally solved this sync speed deficiency with Nikon's pro-grade SLR offerings with its 250th sync. In contrast to the manually operated F2, the F3's electronic shutter required battery power to operate, although the camera included a small backup mechanical release lever that tripped the shutter at 1/60 sec. The F3 continued the high quality of its predecessors, in some ways surpassing it. Tolerances were exacting, and typically Nikon – just enough for operation of the camera (with a small allowance for debris), yet not enough to inhibit cold-weather operation at temperatures where lubricants begin to gel. Only the finest quality mechanical and electronic parts were selected, and Nikon insisted that all electronic components be sourced with a guarantee of 20 years of continued supply. Not only did the F3 use ball-bearings to mount its shutter and film transport mechanisms, but additional clusters of bearings were added to the film advance to make one of the smoothest operating cameras ever built. Indeed, resistance is so low when operating the film advance that it is difficult to tell if there is film in the camera. For the first time, shutter information was displayed via an internal liquid crystal display (LCD) inside the viewfinder. Aperture information was relayed through Nikon's "ADR" (Aperture Direct Readout) which was a window at the top center of the viewfinder that got its information from a
