Manufacturer description

BEIJING, China – April 19, 2012 – Samsung Electronics Co., Ltd, a global leader in digital media and digital convergence technologies is breaking new ground with its award-winning NX series with three new compact system cameras (CSC) that pioneer built-in Wi-Fi connectivity: the NX1000, NX210 and NX20. Now professional quality images can be easily captured, shared and stored straight from your camera – wherever you are in the world.

Introducing the NX1000, NX210 and NX20

The innovative additions to Samsung’s NX range represent the future in CSC technology: SMART cameras with in-built Wi-Fi technology that allow users to connect to wireless networks without any additional cards or devices. Full Wi-Fi connectivity is complemented by an impressive range of features, continuing the heritage of innovation that the NX series has been consistently recognized for since the launch of the NX10 in 2010.

As standard, all three NX models feature a 20.3 Megapixel APS-C CMOS sensor, developed in-house by Samsung to give high quality images in rich color and detail. They are also fully compatible with the NX series’ unique i-Function system, enabling users to control parameters using the lens itself, adjusting the image without ever having to move off target. With Samsung’s range of nine lenses and professional standard accessories, the NX eco-system ensures that all imaging ambitions can be realised, whatever the user’s photographic speciality or interest.

Enhancing Samsung’s 2012 SMART CAMERA ecosystem, these latest additions to the NX range have been designed to satisfy the ambitions of users of all abilities, whether an experienced professional or someone just looking to trade-up from their point-and-shoot.

The NX1000 is highly portable and its eye-catching compact design makes it as useable as it is attractive. Available in stunning White, classic Black or eye-catching Pink it houses a feature-rich range of specs, with technology such as Smart Auto 2.0 and the Smart Link Hot Key, making it simpler than ever to shoot and share great images instantly.

The NX210 follows the NX’s design heritage, with a premium metallic finish. Like its predecessor the NX200, the NX210 also offers a 3.0″ AMOLED display for viewing images and Full HD movies in brilliant resolution. With easy access to Wi-Fi functions, the NX210 allows quick sharing with friends and family, whilst with Samsung Mobile Link users can show off their best images on phones and tablets, or on the big screen with TV Link connecting the NX210 wirelessly to internet-enabled TVs.

The NX20 is the perfect match for enthusiast amateur or professional photographers looking for a highly portable camera that gives the professional look and feel of a DSLR but at a fraction of the size and weight, with the addition of an ergonomic grip to fit comfortably into the hand. Delivering impressive speed with its 1/8000s Fast Shutter, breath-taking images are shown on its clear 3.0″ clear AMOLED swivel display, increasing visibility by approximately 20%. The NX20 also incorporates a range of functions and manual controls in order to deliver pro-standard pictures every time, including SVGA EVF so users can frame images like a professional.

In-Built Wi-Fi for simple sharing and saving

With Samsung’s latest SMART features, users can share pictures at the touch of a button, uploading to social networks including Facebook and Picasa, or emailing them to friends and family – all straight from their new NX camera. The cameras also offer further options for capturing and displaying images via other devices, including the ability to link to a Samsung smartphone and use as a remote viewfinder, and – with the Samsung Mobile Link function – to display images on devices such as tablets or internet-enabled TV.

Creative control at the touch of a button

Pictures shared on the spur of the moment are no longer restricted to simply shooting and sending – with the creative features of the new NX cameras, Facebook pictures can be artistic without ever going near a computer. The ten Smart Filters and added Selective Color function, for example, mean that users can adjust the look and feel of shots as they take them. In addition, all three cameras also feature Panorama and 3D Panorama, allowing the whole story to be told in one complete picture. With the Smart Panel featured on all the new models, settings and features can be easily accessed and applied, making creative photography easier than ever.

Mr. Myoung Sup Han, Senior Vice President and Head of the Digital Imaging Business, Samsung Electronics, commented: “The three new additions to the NX range mark an evolution in Samsung’s SMART CAMERA offering, demonstrating our understanding that digital imaging is about sharing the best moments with family and friends, and not only about taking great pictures. Samsung is paving the way, introducing the world’s first SMART Compact-System-Cameras for professional standard images that are worth sharing.”

“With the inclusion of in-built Wi-Fi connectivity, our customers can now share pictures and videos straight from their NX camera. More importantly, however, the NX camera’s wireless connectivity does not mean sacrificing fantastic image quality – you can now have the best of both at your fingertips. This dedication to innovation will make Samsung a leader in the SMART CAMERA market.”

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.
