A Nikon D3s não é simplesmente a D3 com gravação de vídeo a 720p (como a D300s em relação à D300). Um novo sensor permite capturas com ISO 102.400. Sim, isso é um ISO de seis dígitos.
O sensor da D3s é uma forma evoluída do full-frame de 12,1 megapixels da D3 original, com uma estrutura diferente para melhorar a relação sinal para ruído ao fotografar em ISO mais alto, mais novos algoritmos e melhor processamento de imagem. O alcance normal de ISO é de 200 a 12.800, e no modo expandido ele vai até 102.400. Mas mesmo fotos com ISO não tão alto, tipo 6.400, devem sair melhor do que na D3. A Nikon diz que ISO 6.400 e 12.800 seriam “confortáveis” para fotografar.
A notícia desapontadora é o vídeo a apenas 720p – nada de 1080p. (A Nikon diz que é porque a câmera é voltada para fotojornalistas, que não querem ou precisam de 1080p.) Mas o vídeo tira vantagem da alta sensibilidade da D3s, com um grande alcance dinâmico no modo High Sensitivity Movie. No geral, o modo de vídeo da D3s é mais capaz do que os das outras DSLRs da marca, com controle completo de abertura, foco automático mais rápido no live view e entrada para áudio estéreo. Um novo algoritmo supostamente suaviza alguns dos problemas de vídeo de outras câmeras.
Outras melhoras em relação à D3 incluem um buffer maior para mais disparos contínuos (burst), limpeza automática do sensor de imagem e inicialização e foco automático mais rápidos. O corpo, a bateria e tudo mais é basicamente o mesmo – afinal, é uma D3 evoluída, não reinventada.
Ela sai em novembro por US$ 5.200, ou US$ 200 a mais do que a D3 custava quando foi lançada. É difícil dizer qual será exatamente a sua posição no mercado, já que os principais sistemas profissionais da Canon estão atualmente um pouco ultrapassados, o que deixaria a D3s virtualmente sem competidores, pelo menos por enquanto. Veremos.
THE IMAGING EVOLUTION CONTINUES: THE NIKON D3S ILLUMINATES NEW LEVELS OF POWER AND PERFORMANCE FOR PROFESSIONAL PHOTOGRAPHERS
Nikon Once Again Redefines Possibilities with D-SLR Photography with Six-Figure ISO Sensitivity for Stills and Video While Enhancing Overall Performance
MELVILLE, N.Y. (Oct. 14, 2009) – Today, Nikon Inc. announced the FX-format D3S D-SLR, providing professional photographers with a powerful tool that redefines the boundaries of digital SLR versatility, while maintaining the strength of superior image quality and high speed performance inherited from the ground breaking D3. The D3S enables not only new opportunities in low-light photography, but also provides photographers with added shutter speed and aperture freedom with a base ISO sensitivity range from ISO 200 to a remarkable 12,800. Additionally, expanded ISO equivalent settings up to a staggering 102,400 are available, enabling photographers to create images previously thought impossible.
The Nikon D3S builds upon the success of the Nikon D3-the professional digital SLR that set new standards for D-SLR performance and utilizes a newly designed, Nikon original 12.1-megapixel FX-format CMOS sensor that also integrates its amazing low-light ability to High Definition (HD) video, creating a uniquely capable multi-media tool to meet the needs of a changing imaging landscape.
"When the Nikon D3 was released, it ushered in a new era of professional digital imaging. Today, the D3S will further reinforce Nikon’s leadership role in the photographic industry as a pioneer in performance-driven technologies that will again break once-rigid picture-taking barriers," said Edward Fasano, general manager for Marketing, SLR Systems Products at Nikon Inc. "The ruggedly constructed D3S was engineered to address the real-world needs of professional photographers and provides them with a tool that, when combined with their skills, delivers stunning images in a broad range of shooting conditions and assignment requirements."
Creative Vision Beyond the Human Eye
The Nikon D3S, with a base ISO sensitivity from ISO 200 to 12,800 makes it possible to capture previously impossible images-image opportunities which were often ignored because of low light levels. Now, in even more demanding lighting conditions, photographers can select expanded sensitivity settings of ISO equivalent 25,600, ISO equivalent 51,200 and an incredible ISO equivalent sensitivity of 102,400 which reveals detail in extreme low-light environments that challenge even the human eye’s ability to discern subject content. In addition, a setting of ISO equivalent 100 is provided.
This industry-first, groundbreaking ISO sensitivity range will make the D3S the camera of choice for photographers who typically face extreme lighting challenges, such as indoor or nighttime sports, spot news, wedding receptions and ambitious nature photography. This broad ISO sensitivity also affords the ability to shoot at faster, action-stopping shutter speeds. D3S shooters will enjoy a major advantage in any situation where light is limited and the use of supplemental lighting is not an option. For the photojournalist, even the highest ISO setting delivers image quality to satisfy the needs of offset printing.
Big Pixels Equal Greater ISO Capabilities
The amazing low-light ability of the D3S, as well as its astounding image quality can be attributed in large part to the engineering behind the newly designed, Nikon original 12.1-megapixel FX-format CMOS sensor, which measures 36×23.9mm. While the pixel size and count that served the D3 were maintained to deliver the pinnacle of image quality, dynamic range, phenomenal tonal gradation and outstanding color, other aspects were engineered to add versatility through broader low-noise ISO sensitivity. Individual pixels measure a large 8.45 microns, which support enhanced sensitivity to light and other qualities leading to superior image fidelity. The D3S captures light and renders images in a way that no other Nikon camera has yet to achieve, with a higher signal-to-noise ratio and an unmatched dynamic range for both stills and HD video throughout its broadened ISO range.
D3S adds the extra benefit of an Image Sensor Cleaning function to reduce instances of image degradation resulting from dust accumulation on the optical low pass filter (OLPF) in front of the image sensor. The OLPF oscillates at four specific frequencies to release particles that would disrupt image quality. Sensor Cleaning can be set by the user to cycle automatically when the camera is powered on, turned off, or on demand.
Share the Vision with D-Movie Creativity
Whether on the frontlines or sidelines, the amazing ISO range of the D3S can also be applied while recording HD video clips to give unprecedented low-light ability for movie clips. The refined D-Movie mode for the FX-format offers smooth 1280×720 video at a cinematic 24fps, with a new algorithm that severely reduces the phenomenon of "rolling shutter" typical to D-SLRs while panning. The motion JPEG codec allows for easy extraction of single frames from a video clip and the ability to save it as a JPEG file, while the 720p HD format eases storage, provides faster wireless transfers, and offers video files that are generally easier to use in the field. Photographers can also trim movie clips on the fly by revising the start and end points, and save the edited clip as a copy while maintaining the original. Additionally, the D3S features a built-in monaural microphone, augmented by a stereo microphone input, which is perfect for hot-shoe microphone mounting or the use of wireless microphones for interviews or spot news.
Photographers and film makers alike will appreciate the full aperture control from a wide f/1.4 to f/16, as the FX-format sensor renders low-noise movie clips with outstanding clarity, aided by the large selection of renowned NIKKOR lenses to produce a dramatic depth of field. High Sensitivity Movie Mode allows the utilization of the entire ISO range to capture otherwise hidden details in challenging lighting conditions, more effectively than cameras with smaller sensors. Now, users can benefit from available natural light for applications such as telling a story in a journalistic style in the field or to create a gritty film noir masterpiece without CGI post production. While recording, users also have the ability to control exposure, and will enjoy the added benefits of improved contrast-detect type AF while in Tripod Live View mode.
Performance and Features Defining Versatility
The emergence of the D3 in 2007 provided photographers with a unique fusion of ruggedness, speed, versatility and image quality-characteristics which the D3S now takes even further. Photographers are able to capture images at 9 frames per second (fps) in the FX-format or at up to 11 fps in the DX crop mode, while data is transferred through a 16-bit pipeline for optimal processing speed. Additionally, the buffer has been increased, enabling continuous bursts approximately twice that of the D3 in the JPEG, TIFF or NEF (RAW) formats. Files can also be captured in either 12- or 14-bit compressed or uncompressed formats to maintain the images data integrity. Photographers can also select the new 1.2x crop mode for a modest telephoto effect, while minimally impacting resolution, as photos are captured at approximately 8.4 megapixels (9 fps).
The D3S digital SLR also features two UDMA compatible CompactFlash™ card slots that can be used for consecutive recording (overflow), simultaneous recording (backup), separating recording of RAW and JPEG files or even copying pictures between the two cards. One or both can also be designated for data-heavy D-Movie recording. Images can be displayed directly from the camera to a High Definition monitor using the camera’s HDMI port and an optional cable.
The D3S features Nikon’s exclusive Multi-CAM 3500FX focus module, with 51 AF points, 15 cross type sensors and 36 horizontal sensors that easily track and lock onto moving subjects, delivering the same fast and accurate AF performance that helped make the D3 immediately successful. Users can select any of the AF points, making it easy to consistently attain accurate focus, frame after frame. Additionally, three AF-area modes – Single point, Dynamic-area AF and Auto-area AF – are available to maximize the use of the 51 focus points by selecting the most suitable one to match subject conditions. AF is also available in one of two Live View modes optimized for the studio, including a phase detection handheld mode and a tripod mode. While in Live View, the graphic indication of a virtual horizon is also available, making it easier than ever to confirm camera orientation.
To alleviate another kind of noise, the D3S also features a Quiet Shutter Mode which substantially reduces the sound of the camera’s mirror-down cycle, which is perfect for shooting in sensitive environments, such as movie sets, meetings, ceremonies, or while photographing wildlife.
Technologies Engineered for Professionals
The D3S digital SLR’s speed and performance is the culmination of many Nikon core technologies including the latest generation of the EXPEED™ Image Processing System. The latest iteration of this system is specially designed to keep pace with the D3S’ blazing performance to provide amazing image quality, faster processing speeds and lower power consumption. This advanced system is able to achieve extremely precise color reproduction for a broad spectrum of hues, in addition to vivid saturation and smooth gradation. Nikon’s advanced noise processing function is engineered to minimize noise at all sensitivities and operate seamlessly without interfering with other image color parameters.
The D3S’ accelerated Scene Recognition System analyzes information from the 1,005-pixel RGB light sensor for use in auto exposure, auto white balance detection and autofocus calculations. The Scene Recognition System also assists autofocus by tracking subject position and automatically shifts the AF points used to match the subject’s movement within the frame.
Nikon’s exclusive 3D Color Matrix Metering II assists in ensuring accurate exposures, even in the most challenging lighting conditions. Instantly evaluating each scene before capture, input data from the system’s sensor is automatically referenced against an internal database of more than 30,000 images derived from actual photographs to calculate correct exposure values. Active D-Lighting (ADL), used in combination with 3D Matrix Metering II helps to determine proper exposure, and creates realistic contrast while compensating for lost shadows and highlights. Photographers can also use ADL bracketing for up to five frames of ADL compensation.
To further enhance each photographer’s expression of personal style, Nikon’s Picture Control System allows selection of Picture Control settings including Standard, Neutral, Vivid and Monochrome. Additionally, adjustment can be made to Picture Controls to image sharpening, contrast, brightness, saturation, hue and more. Photographers then have the flexibility to save up to nine personalized Picture Controls on camera and 99 additional Picture Controls externally.
Ready for Work
Engineered for real-world functionality, the D3S is ruggedly constructed with moisture, dust and shock resistance that has become a hallmark of flagship Nikon D-SLRs, while preserving the usability and ergonomics that allow the camera to remain an extension of the photographer’s vision. Attention to detail goes so far as to include a self-diagnostic shutter system that is tested to 300,000 cycles for maximum accuracy and longevity. Rigid and precise magnesium alloy construction and the familiar form factor of the D3 extend consistent Nikon system synergy.
A bright and accurate viewfinder provides 100-percent coverage with 0.7x magnification. The body also houses Nikon’s acclaimed 921,000-dot, 3.0-inch super density LCD monitor which is viewable up to 170 degrees, and is safeguarded by a tempered glass cover. Thanks to incredibly efficient internal circuitry, the D3S can capture up to 4200* shots per single charge of the camera’s Lithium-ion battery.
System Strength Withstands the Test of Time
The D3S is fully compatible with Nikon’s Creative Lighting System (CLS) affording photographers a mobile lighting solution that is easy to manage. D3S is also compatible with Nikon’s GP-1 GPS receiver to gather information such as latitude, longitude, altitude and (satellite) date of shooting. Photographers can shoot tethered via USB, or use the WT-4A wireless transmitter to send images wirelessly when speed and mobility are essential. D3S users will also enjoy the system strength bolstered by a comprehensive selection of NIKKOR interchangeable lenses-long heralded for their optical superiority.
