Focal length

The distance from the principal point to the focal point. In 35mm-format cameras, lenses with a focal length of approx. 50mm are called normal or standard lenses. Lenses with a focal length less than approx. 35mm are called wideangle lenses, and lenses with a focal length more than approx. 85mm are called telephoto lenses. Lenses which allow the user to continuously vary the focal length without changing focus are called zoom lenses.

Focus Tracking

Enables the camera to analyse the speed of a moving subject according to the focus data detected, and to obtain correct focus by anticipating the subject’s position—at the exact moment of exposure.

Lock-On™ Autofocus keeps focus firmly on a main subject during Focus Tracking even if some other object momentarily blocks it in the viewfinder.

Front-Curtain Sync

The flash fires an instant after the front curtain of a focal plane shutter has completed its travel across the film plane. This is the way the F65/F65D operates with the flash sync mode at Normal Sync. (See “Rear-Curtain Sync”.)

Guide number

The guide number indicates the power of a flash in relation to ISO film speed. Guide numbers are quoted in either meters or feet. Guide numbers are used to calculate the f/stop for correct exposure as follows:

guide number

f/stop = ———————————

flash-to-subject distance

Using a selected aperture, we can calculate the required flash-to-subject distance with the formula:

guide number

flash-to-subject distance = ———————

f/stop

Useful for determining the maximum flash-to-subject distance for flash photography.

ISO film speed

The international standard for representing film sensitivity. The higher the number, the greater the sensitivity, and vice versa. A film speed of ISO 200 is twice as sensitive as ISO 100, and half that of ISO 400 film.

Rear-Curtain Sync

Flash fires an instant before the second (rear) curtain of the focal plane shutter begins to move. When slow shutter speeds are used, this feature can create a blur effect from the ambient light, i.e., flowing-light patterns following a moving subject with subject movement frozen at the end of the light flow. (See “Front-Curtain Sync”.)

Slow Sync

A flash technique for using the flash at a slow shutter speed. Flash shooting in dim light or at night at a fast shutter speed often results in a flash-illuminated subject against a dark background. Using a slower shutter speed with the flash brings out the background details in the picture. Use of a slow shutter speed with Rear- Curtain Sync is particularly effective for illustrating the movement of a stream of light.

The F65/F65D’s Slow Sync mode extends the automatically controlled shutter speed range down to 30 sec. (in Auto-Multi Program, Aperture-Priority Auto) or 1 sec. (in h Night Scene mode).

Vignetting

Progressively diminished illumination on the film from the centre to the corners. There are two kinds of vignetting—natural vignetting caused by the lens, and vignetting that is caused by improper use of accessories such as a lens hood or filter.

F65D specifications

The Nikon F65D, also known as the Nikon N65 in some regions, is a notable entry in the world of 35mm film cameras, bridging the gap between traditional photography and the emerging digital era. Released in the late 1990s, this camera embodies a blend of versatility, user-friendly controls, and solid build quality, making it an appealing choice for both amateur photographers and seasoned professionals seeking a reliable film camera.

One of the main features of the F65D is its autofocus system. The camera is equipped with a 3D Color Matrix Metering system that ensures accurate exposure calculations, enabling photographers to capture vibrant images with rich tones. The autofocus system consists of a five-point AF module, offering users flexibility in focusing on subjects in various shooting conditions. This is particularly advantageous for capturing dynamic scenes where precise focus is critical.

The F65D also boasts multiple exposure modes, including program, aperture priority, shutter priority, and manual mode. This variety allows users to explore different techniques and styles of photography, adapting to their creative vision. The camera's built-in pop-up flash ensures that even low-light conditions can be managed effectively, providing additional versatility when shooting indoors or during twilight hours.

In terms of design, the Nikon F65D is ergonomic, featuring a comfortable grip that facilitates prolonged shooting sessions without discomfort. The camera's LCD panel displays essential information, such as shutter speed, aperture, and exposure compensation, making it easy to track settings at a glance. Moreover, the lightweight and compact nature of the F65D enhances its portability, allowing photographers to carry it easily during travel or outdoor adventures.

Another notable characteristic of the F65D is its compatibility with a wide range of Nikon F-mount lenses. This extensive selection means users can choose from various focal lengths and aperture sizes, expanding their creative possibilities. Whether you're interested in landscape photography, portraits, or macro shots, the F65D can accommodate different lenses to suit specific needs.

The Nikon F65D stands out not only for its technical features but also for its reliability and durability. Built with a robust chassis and quality materials, it's designed to withstand the rigors of everyday use while providing dependable performance. In conclusion, the Nikon F65D is an excellent choice for photographers who want to experience the beauty of film photography, offering a balance of advanced technology and user-friendly features that make capturing stunning images an enjoyable experience.
