for ASAIISO 100 in Section B, and go down diagonally until the protruding line intersects with Section C's vertical line for a shutter speed of 1/2000 sec . (the F3AF'sfastest shutter speed) this time. Then follow the horizontal line that leads to Section D's EV value for ASA/ISO lOa, and you will get a reading of EV

16.This means that at an flstop of 1/5.6 at ASAIISO 100 and at shutter speeds from 8 to 1/2000 sec ., the effective metering range is EV 2 to 16, which is well within the F3AF'smetering range of EV 1 to EV 18.

The green area in Chart 1 encompassed by the heavy lines in Section C demonstrates the usable shutter speed range to match any film speedlaperture combination at ASAIISO 100. (The minimum aperture of the lens is 1/16.)

Similarly in Chart 2, the usable range (at ASAIISO 100) for the AF -Nikkor 80mm f/2.8lens is shown in green .

Two red lines in Section C of both charts indicate the EV value ranges of the scene brightness usable with autofocus or focus- aid operation . Therefore, the combinations of shutter speeds and apertures indicated in the areas outside the lines are not usable.

Stop-down metering

For stop -down metering, Section A indicates the usable EV range for various aperture settings. For example, if the lens is stopped down to f/8 at ASAIISO lOa, refer to the f/8 column in Section A and the EV values indicated for ASAIISO 100 in section D, and you will find that the EV range for f/8 is EV 6 to

23.Now single out f/8 at ASAIISO 100 in Section B. Go diag - onally down until the protruding line intersects with Section C's vertical line for the shutter speed of 8 sec . From this point of intersection , follow the horizontal line that leads to Section D's EV value for ASAIISO lOa, and you will obtain an EV reading of

3.This means that an flstop of f/8 at ASAIISO 100 and a shutter speed of 8 sec. give an EV value outside the metering range . To find out the slowest shutter speed usable, follow the f/8 indi- cation for ASAIISO 100 in Section B diagonally down until it intersects the horizontal line in Section C that leads to Section D'sEV value of 6 for ASA/ISO 100, and you will find that the slowest shutter speed usable is 1 sec. In other words, at f/8 at ASAIISO lOa, the available shutter speed range from 1 to 1/2000 sec. has an effective EV range from EV 6 to 17 (indicated by the broken line in Section C)-well within the metering range .

F3AF specifications

The Nikon F3AF, introduced in 1983, is a landmark camera in the history of photography, notable for its pioneering autofocus capabilities. As one of Nikon's first professional autofocus cameras, the F3AF combines the robust features of the F3 series with advanced technology to offer photographers a powerful tool for capturing high-quality images.

One of the standout features of the F3AF is its autofocus system, which employs a sophisticated phase detection mechanism. This represents a significant leap forward from the manual focus cameras that dominated previous generations. The system can quickly and accurately lock onto subjects, making it easier for photographers to capture sharp images, particularly in dynamic or fast-paced situations.

The F3AF retains the iconic design and build quality of the F3, characterized by its rugged, weather-sealed construction that ensures durability in various shooting environments. The camera body features a comfortable grip and a solid metal chassis, appealing to professionals who require reliability and performance in the field.

Another key characteristic is its compatibility with a wide range of Nikkor lenses, including the autofocus Nikons. This flexibility allows photographers to choose the appropriate lens for their specific needs, whether they are shooting landscapes, portraits, or sports. The camera features a unique "Auto Focus" mode which works in tandem with specialized AF lenses to streamline the focusing process.

In terms of exposure modes, the F3AF offers automatic exposure through its TTL (Through The Lens) metering system. This capability allows for accurate exposure readings, helping photographers achieve optimal results in various lighting conditions. Additionally, the camera features multiple shooting modes, including manual, aperture priority, and shutter priority, accommodating the preferences of both novice and seasoned photographers.

Furthermore, the F3AF supports an array of accessories, including motor drives and special viewfinders, allowing photographers to enhance their shooting experience. The camera's electronic viewfinder provides a bright and clear display, giving users a precise view of their composition.

Despite being released decades ago, the Nikon F3AF remains a respected choice among film enthusiasts and collectors, representing a significant achievement in photographic technology. Its blend of innovative autofocus functionality, robust design, and versatile features make it an enduring symbol of Nikon's commitment to excellence in the world of photography.
