Velocidade proeminente e definição para o fotógrafo discernindo: o EOS 50D
Amstelveen, os Países Baixos, 26 agosto 2008: Canon strengthens hoje sua escala do EOS com a adição de um SLR digital novo poderoso: o EOS 50D. Com um sensor 15.1 de Megapixel CMOS, 6.3 frames por disparar do segundo e o processador de imagem o mais atrasado de DIGIC 4 de Canon, o EOS 50D entrega velocidade unparalleled e definição em um ponto do preço que seja original no mercado de hoje.
As imagens proeminentes, limpas
A projetaram recentemente o sensor 15.1 de Megapixel CMOS entregam as imagens ultra-detalhadas, low-noise - ideais para a reprodução em grande escala ou o cropping creativo. Os processos de manufacturing novos, diodos redesigned positivos da foto e microlenses, estendem as potencialidades de recolhimento claras do sensor - permitindo que mais pixels sejam cabidos no sensor do CMOS sem a qualidade comprometendo da imagem. Estas mudanças asseguram o desempenho elevado melhorado do ISO e o ruído baixo. Disparar da luz de alta velocidade, baixo é permitido pelos níveis do ISO de 3200, expansíveis a uns 12800 ultra-sensíveis.
O sistema de limpeza integrado EOS - including a unidade melhorada do sensor da limpeza do Self com um revestimento novo do fluorine - proteção dos aumentos da qualidade da imagem ajudando reduzir-se, repele e remove poeira não desejada do sensor. As partículas Stubborn podem ser removidas automaticamente na borne-produção com os dados da supressão da poeira e o software incluído do profissional da foto de Digital de Canon.
o processador novo
de DIGIC 4 de Canon do desempenho do Rápido-fogo é rapidamente bastante permitir até disparar 6.3fps contínuo, nos estouros de até 90 JPEGs com um cartão de UDMA. Usado com sistema largo do AF da área de Canon, que trava em assuntos com 9 tipo transversal individual sensores, as seqüências stunning da ação podem ser capturadas - mesmo em condições da baixo-luz. Isto faz o EOS 50D servido particularmente aos esportes e a disparar dos animais selvagens.
DIGIC 4 works with the CMOS sensor to deliver 14-bit image processing, for smooth gradation and natural-looking colours – as well as ensuring ultra-fast startup times and near-instant image review after shooting.
See everything
A new 3.0” Clear View VGA LCD provides extra-large and wide angle-of-view image review, with plenty of clarity for accurate focus checks in playback. By switching to Live View mode – which displays a real-time image on the LCD – photographers can enjoy simplified shooting from awkward angles, or connect to a PC for remote shooting. Live Mode now offers three ways to auto focus: Quick AF, Live AF, and new Face Detection Live AF, which optimizes focus based on faces detected in the frame – for fast, spontaneous portraiture.
Control and ease
The famously intuitive EOS menu system includes a new Quick Control screen, for instant access to the most commonly-changed settings. A new Creative Auto mode offers automatic focus and exposure – while still allowing creative ‘tweaks’ to settings such as background sharpness.
“For advanced amateurs and semi-professionals – or professionals looking for a powerful backup model – the EOS 50D stands alone,” said Mogens Jensen, Head of Canon Consumer Imaging, Europe. “No other camera in this price bracket offers a comparable combination of speed and image quality.”
Technologies Explained
CMOS
Canon’s CMOS technology is one of the company’s key competitive advantages, with noise reduction circuitry at each pixel site delivering virtually noise-free images. In comparison with CCD technology, the lower power consumption characteristics of Canon’s CMOS sensors also contribute to longer battery life.
Signal conversion in Canon’s CMOS sensors is handled by individual amplifiers at each pixel site. Unnecessary charge transfer operations are avoided, vastly speeding up the process of getting signal to the image processor. Noise generation is reduced, power consumption is limited and faster frame rate potential is increased.
DIGIC
Image data captured by the CMOS sensor is processed by Canon’s purpose-built DIGIC image processors before being written to the camera's memory card. DIGIC technology uses advanced image processing algorithms to ensure precise, natural colours, accurate white balance, and advanced noise reduction. Ultra-fast processing speeds result in highly responsive camera operation and near-instant start-up times.
DIGIC chips work with a high speed DDR-SDRAM image buffer – reading, processing, compressing and writing image data fast enough to keep the buffer clear during long continuous shooting bursts. And because DIGIC integrates all key processing functions, power consumption is kept to a minimum.
EOS Integrated Cleaning System
The EOS Integrated Cleaning System combats sensor dust in three important ways: Reduce, Repel and Remove.
1. Reduce - Internal camera mechanisms are designed to minimise dust generation. The redesigned body cap prevents dust generation through wear on the cap itself.
2. Repel - Anti-static technologies, including a special fluorine coating, are applied to the low-pass filter covering the front of the sensor so as not to attract dust.
3. Remove - A Self-Cleaning Sensor Unit uses hi-frequency vibrations to shake dust from the infrared filter for a period of approximately one second after each start up. For instant shooting after power up, this feature is disabled immediately the shutter release is depressed.
Canon has also developed an internal Dust Delete Data system, which can map the position of visible dust on the sensor. This can then be deleted automatically after the shoot with the latest Digital Photo Professional software.
Picture Style
Picture Style pre-sets simplify in-camera control over image qualities. Picture Style pre-sets can be likened to different film types – each one offering a different colour response. Within each selectable pre-set, photographers have control over sharpness, contrast, colour tone and saturation. The camera’s factory default configuration is set to deliver immediately-usable JPEG images without need for additional menu settings. Picture Style presets applied to a RAW image can be revised with Canon’s Digital Photo Professional software.
The six pre-sets are:
1. Standard – for crisp, vivid images that don’t require post-processing
2. Portrait – optimises colour tone and saturation and weakens sharpening to achieve attractive skin tones
3. Landscape – for punchier greens and blues with stronger sharpening to give a crisp edge to mountain, tree and building outlines
4. Neutral – ideal for post-processing
5. Faithful – adjusts colour to match the subject colour when shot under a colour temperature of 5200K
6. Monochrome – for black and white shooting with a range of filter effects (yellow, orange, red and green) and toning effects (sepia, blue, purple and green).
Software
Digital Photo Professional Software
Digital Photo Professional software provides high speed, high quality processing of lossless RAW images. Processing with Digital Photo Professional allows real-time display and immediate application of image adjustments, giving control over RAW image variables such as white balance, dynamic range, exposure compensation, noise reduction and colour tone – plus the ability to view Auto Focus points on an image. The Lens Aberration correction tool allows precise correction of different types of distortion caused by certain cameras. Images can be recorded in camera with sRGB or Adobe RGB colour space.
Digital Photo Professional supports sRGB, Adobe RGB, ColorMatch RGB, Apple RGB and Wide Gamut RGB colour spaces. ICC (International Colour Consortium) profiles can be attached to TIFF or JPEG images when converted from RAW. This allows faithful reproduction of colours in software applications that support ICC profiles, such as Adobe Photoshop. For improved efficiency, a set of image adjustments can be saved as a recipe and applied.
EOS Utility
The latest version of EOS Utility provides essential support for Live View remote shooting, camera configuration and image transfers. Tightly integrated with Digital Photo Professional, EOS Utility can be configured to monitor ‘hot’ folders, automatically renaming and moving incoming images to a structured file system. Users can also tag their images with EXIF data, including copyright information.
Picture Style Editor
Picture Style Editor allows users to create individual Picture Styles that fit with their personal requirements. Each Picture Style contains detailed information on how specific colours should be represented within an image. Once new Picture Styles have been created, they can be uploaded directly into the camera and applied to JPEG or RAW images. When working with RAW files in DPP, both personal Picture Styles and the 6 predetermined Picture Styles can all be adjusted.
