Manufacturer description

TOKYO – Nikon Corporation is pleased to announce the introduction of a new entry level interchangeable-lens digital SLR camera designed to make it easier than ever to enjoy the thrill of outstanding digital SLR picture quality easily and instantly. Combining the outstanding response of Nikon's patented digital and photographic performance with optical performance available only from renowned Nikkor interchangeable lenses and expanded shooting options only available in a quality digital SLR camera, the new Nikon D50 makes exceptional digital SLR photography a reality for everyone.

The next evolution of Nikon's scene-optimized Digital Vari-Program modes simplifies picture taking, freeing the photographer to concentrate on capturing the evanescence of special moments. Selecting one of the seven easily distinguishable icons from the handy exposure mode dial optimizes otherwise complex settings and ISO-equivalent sensitivity to produce consistently remarkable results. Newly added is "Child" mode, which makes it easier to take memorable pictures of the little ones complete with ideal vivid color and contrast – ready to print beautifully without the fuss of later adjustments at the computer. Full manual exposure control is also available, allowing more advanced photographers all the creative freedom they desire, while also making it possible for all photographers to expand their enjoyment of photography.

The D50 features a new 6.1 effective megapixel Nikon DX Format CCD image sensor and a highly advanced image processing engine that team together to create truly faithful image files capable of significant enlargement, yet remain manageable in overall file size, making it easier to take and store more great pictures. These optimized components produce more consistent results, even under shooting conditions that challenge other digital cameras, such as when working with light-colored subjects or long exposure shots.

Distinguishing itself over lesser systems, the Nikon D50 is always ready to shoot when that special moment or expression presents itself. When the power is turned on, the camera is ready to shoot in just 0.2 seconds for near-instant readiness. The shutter's release lag time is also minimized for near-instant response that virtually eliminates a common frustration of digital photography.

Continuous shooting at 2.5 frames per second can be maintained for bursts of up to 137† pictures, making action photography a reality. Pictures taken are instantly processed and recorded to the photographer's compact SD (Secure Digital) memory card. A new USB 2.0 Hi-Speed interface supports faster transfer of images when connected to a compatible computer.

Shutter speed choices extend from 30 sec. to an action-stopping 1/4,000 sec. A high-speed flash sync speed up to 1/500 sec. makes great fill flash photography possible, and Nikon technology makes it automatic. A bulb setting is also included for long exposures. The shutter is designed to ensure fast curtain action for consistent operation and accurate, predictable results, even at high shutter speed settings. AUTO ISO maximizes available light by automatically setting ISO-equivalent sensitivity across the available range of 200 to 1600. D50 photographers can also opt to set the ISO sensitivity manually for personal control.

The D50’s 5-area autofocus system inherits Nikon's proven cross-type center sensor, broad frame coverage, and class-leading low light detection found only in the award-winning Nikon D70 camera, and delivers even greater AF precision with fast, more consistent subject acquisition and improved focus tracking. The new system adopts AF-A mode for smooth automated operation that switches between AF-S (single-servo autofocus) and AF-C (continuous-servo autofocus) depending on the movement of the subject in the framed shot. An AF-assist illuminator is also included, which helps maximize performance when shooting in low lighting conditions.

The D50 produces consistently natural coloration by measuring the entire frame of the shot and matching white balance to the light source. Advanced auto white balance handles most lighting situations, but the flexible options include a choice of six specific manual settings, white balance bracketing for added creative choice of results, as well as a preset option for using a gray or white object as a calibrating reference under mixed lighting conditions.

Nikon's new 3D Color Matrix Metering II ensures accurate exposure control in most types of lighting situations by automatically comparing input from its frame-wide 420-pixel sensor for each scene to a large onboard database of over 30,000 scenes from actual photography. Professionals and amateurs alike rely on Nikon's exclusive light metering technologies that produce ideal exposures instantly. Newly developed exposure evaluation methods detect highlights and shadows in the frame, and compensate for them to help minimize under- or over-exposure by comparing the lighting pattern of the frame with the onboard database of scenes, thus enhancing performance for more accurate and consistent exposures.

A key advantage and one source of the fun associated with Nikon digital SLR photography is the ability to take advantage of the creative possibilities offered by interchangeable lenses. The new D50 offers seamless compatibility with Nikon's extensive family of high-performance AF Nikkor lenses, as well as the expanding family of digital-dedicated DX Nikkor lenses, providing superb color reproduction, razor-sharp image clarity and fast and accurate autofocus performance.

The compact, light-weight design of the new D50 makes it easy to carry on any outing, while its body contours and easily accessible controls provide handling efficiency and easy operation. Newly designed on-screen menus present clear and helpful user information in plain language on the D50's large 2.0-inch LCD monitor, and intuitive help dialogs are available for on-the-spot reference to the respective menu selections. The high-capacity rechargeable lithium-ion battery helps extend mobility and convenience by delivering the power to shoot up to 2,000 images†† on a single charge.

The D50 is an outstanding performer, right down to its diverse playback options, versatile custom settings, USB 2.0 Hi-Speed interface for easy connectivity or direct printing to any PictBridge compatible printer with in-camera page setup, and Nikon's complimentary PictureProject software that will extend anyone’s photographic experience with easy image transfers, effective image organization and editing, creative page layout design, plus printing and sharing. PictureProject’s new version 1.5 provides customers with an exceptional added value topped only by its excellent performance.

These inherit advantages combine with the empowering and creatively inspiring components of Nikon's Total Imaging System, including high-quality AF and DX Nikkor lenses, the SB-800 and SB-600 Speedlights, which enable use of Nikon's Creative Lighting System, as well as versatile software options, to deliver a new level of operating ease, expanded creative possibilities, and pure enjoyment. The Nikon D50 presents the perfect opportunity for anyone to start enjoying the advantages of Nikon digital SLR photography today.

Sales release schedule: Nikon Corporation will launch the D50 worldwide in June 2005.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/ on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
