The Nikon SP and other 1950s and 1960s rangefinder cameras competed directly with models from Leica and Zeiss. However, the company quickly ceased developing its rangefinder line to focus its efforts on the Nikon F single-lens reflex line of cameras, which was successful upon its introduction in 1959. For nearly 30 years, Nikon's F-series SLRs were the most widely used small-format cameras among professional photographers, as well as by the U.S. space program.Nikon popularised many features in professional SLR photography, such as the modular camera system with interchangeable lenses, viewfinders, motor drives, and data backs; integrated light metering and lens indexing; electronic strobe flashguns instead of expendable flashbulbs; electronic shutter control; evaluative multi-zone "matrix" metering; and built-in motorized film advance. However, as autofocus SLRs became available from Minolta and others in the mid-1980s, Nikon's line of manual-focus cameras began to seem out of date.Despite introducing one of the first autofocus models, the slow and bulky F3AF, the company's determination to maintain lens compatibility with its F-mount prevented rapid advances in autofocus technology. Canon introduced a new type of lens-camera interface with its entirely electronic Canon EOS cameras and Canon EF lens mount in 1987. The much faster lens performance permitted by Canon's electronic focusing and aperture control prompted many professional photographers (especially in sports and news) to switch to the Canon system through the 1990s.Nikon Pakistan brings yet another chance for you to express your extra ordinary photography skills.
