Focus-Aid Operation (Using the Focus Indicators)

With the AF-Nikkor'sA-M switch @ set at M, or with other Nikkor or Nikon Series E lenses having a maximum aperture of 1/3.5 or faster (as listed on page 20), you can use the focus indicators as a guide as you rotate the lens focusing ring. First, center the main subject (if possible, a subject 'svertical line) within the focusing frame; then depress the shutter release button halfway to make the red arrows light up (focus information stays on for 16 sec. after removing your finger). If only the far-focus arrow (<III ) lights up, this indicates that the lens is focused behind the subject, whereas the near-focus arrow (~) indicates that the lens is focused in front of the subject. These red arrows are very convenient, because they tell you in which direction to turn the focusing ring : just turn in the direction of the arrow. When the image is in focus, both red arrows light up continuously.

When there is a big difference between the actual camera-to- subject distance and distance set on the lens, the focus-

impossible warning appears. In this case, turn the focusing ring until one of the red arrows lights up; then continue to turn the

ring until both arrows are lit, indicating sharp focus. If only the far-focus arrow (<III ) remains lit after the ring has been rotated fully counterclockwise, this means the subject is closer than the closest focusing distance of the lens. If the subject is much closer than the closest focu sing distance of the lens, the red X will light up continuously.

In case the red X blinks or lights up continuously and does not disappear even after the focusing ring is turned , this indicates that the focus-aid indication system does not function well with the particular subject or shooting situation (please refer to page 26 for further details).

Note: While shooting fast-moving subjects, one or both of the red arrows may blink to show that the image is quite close to the in-focus zone; for ordinary snapshots, taking the shot even in this situation can produce satisfactory results. However, if sharp focus is mandatory. continue to rotate the focusing ring untif both red arrows light up continuously.

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.
