Manufacturer description

LONDON, UK – September 14, 2010 - Samsung Electronics (UK) Ltd today announces the launch of the unique Samsung NX100 – an innovative mirrorless camera equipped with the world’s first i-Function lens, putting the perfect picture at the fingertips of all photographers through a completely new way of controlling your camera.

The NX100 is set to dominate the new mirrorless camera category. This innovative new camera benefits from Samsung’s expertise across multiple areas of technology, meaning that all its key components are 100% produced by Samsung. This unique process has been combined with Samsung’s detailed and extensive program of consumer research, which provided valuable insights to incorporate into the NX100. The NX100 is also complemented by an extensive line up of lenses and accessories, giving photographers a full package of options with which to explore their creativity.

The launch of the NX100 follows the success of the NX10, Samsung’s first mirrorless camera and the first in the world to feature an APS-C size sensor, which has already changed the way millions of photographers across the globe take pictures, and raised the bar for the industry as a whole. The NX100 shares the industry leading technology of the NX10, such as an APS-C size sensor for quality images and a 3-inch AMOLED screen for clear and easy viewing. However, Samsung takes the mirrorless camera to the next level with the NX100, by incorporating the innovations of the NX10 and improving other areas of the camera’s performance and design. The body of the camera is slim, sleek and stylish, and it also features the intuitive i-Function lens which allows users to control their camera through the lens for the first time. The NX100 also boasts one of the fastest AF on the market today, which ensures that users never miss a moment, as well as an ISO that is raised to a maximum of 6400 for action shots.

The NX100’s shutter button and curved body have been inspired to an attractive natural shape. The lightweight, compact and modern design makes the camera extremely portable, allowing users with a creative flair to carry the NX100 with them anywhere and for any occasion. The NX100 is more than just a camera; it is both a creative tool and an artistic object that makes a bold style statement everywhere it goes.

Mr. SangJin Park, President of Samsung Digital Imaging Division, Samsung Electronics, commented: “Our aim is to lead the mirrorless camera market in the same way we do the DualView category, and the new NX100 is the embodiment of that goal. Samsung has brought together this high quality of imaging technology with intuitive consumer insights based on our in-depth consumer research, which is why we believe that, alongside the NX10, the NX100 will enhance our position in this growing field. Our unique and pioneering i-Function Lens stands out from the competition as an example of our unparalleled innovation which will appeal to every photographer.”

While conventional lenses are passive in controlling camera settings, the unique i-Function Lens is a proactive lens that communicates with the camera body. It delivers total image control with fast manual settings to ensure quick and easy image capture, and also provides customized settings optimized for the lens being used. The lens incorporates an i-Function button which allows users to scroll through manual settings, and a focus ring which is used to easily change parameters for each setting. Users can toggle between shutter speed, aperture, EV, WB, and ISO quickly and easily by simply using the i-Function button and ring on the lens, meaning easier and quicker configuration while shooting.

The NX100 also has a lens priority mode which makes switching between lenses easier than ever. Firstly, each lens is clearly marked with icons that illustrate their main use to help users quickly learn which lens they need to select for any given scene. The lens priority mode provides scene options optimized for the lens being used – for example when a landscape lens is attached the camera will immediately display the landscape mode. Also, when users change to a specialized lens, the camera would recognize the lens type and automatically configure the settings that would best match with the attached lens. Note this latter feature is supported fully on future specialised Samsung lenses.

The NX100’s innovations aren’t confined to the lens – the camera also provides a very creative feature called ‘Smart Filter’. In playback mode, users can apply seven different effects to the picture, such as the vignette, soft focus, fish-eye or miniature effects. The ‘Smart Filter’ provides not just high quality images, but also features that are fun to use.

The fun doesn't stop with still images. The NX100 supports HD movie recording at 720P, to capture the finest details of your memories. It also contains a ‘Sound Picture’ mode that can record audio whilst a photo is taken. To ensure each image is perfect quality, even when lenses are being changed regularly, the NX100 also features a supersonic dust reduction feature to remove any foreign particles from the lens before shooting.

At launch the NX100 will be equipped with a range of innovative lenses and accessories including a compact zoom 20-50mm lens, a small and light 20mm wide angle Pancake lens (to be introduced shortly after launch). Two additional specialized lenses will be made available in the first half of 2011 – a 60mm Macro lens and 18-200mm Super Zoom lens. To expand the lens line-up even further, three more lenses will be introduced by the second half of 2011. The NX system will be further enhanced with more accessories, including an Electronic Viewfinder, Flash and GPS tracker to capture your exact geographical location.

Cannot perform comparison

Cannot compare the lens to itself.

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.
