Canon EOS 50D

by adhiwus on Jun.02, 2009, under Cameras

The EOS 50D. With a 15.1 Megapixel CMOS sensor, 6.3 frames per second shooting and Canon’s latest DIGIC 4 image processor.

Outstanding, clean images
A newly designed 15.1 Megapixel CMOS sensor delivers ultra-detailed, low-noise images – ideal for large-scale reproduction or creative cropping. New manufacturing processes, plus redesigned photo diodes and microlenses, extend the light gathering capabilities of the sensor – allowing more pixels to be fitted on the CMOS sensor without compromising image quality. These changes ensure improved high ISO performance and low noise. High-speed, low light shooting is enabled by ISO levels of 3200, expandable to an ultra-sensitive 12800.

The EOS Integrated Cleaning System – including the improved Self Cleaning Sensor Unit with a new fluorine coating – increases protection of image quality by helping to reduce, repel and remove unwanted dust from the sensor. Stubborn particles can be removed automatically in post-production with Dust Delete Data and Canon’s included Digital Photo Professional software.

Rapid-fire performance
Canon’s new DIGIC 4 processor is fast enough to allow up to 6.3fps continuous shooting, in bursts of up to 90 JPEGs with a UDMA card. Used with Canon’s wide area AF system, which locks onto subjects with 9 individual cross type sensors, stunning action sequences can be captured – even in low-light conditions. This makes the EOS 50D particularly suited to sports and wildlife shooting.

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.

D3 DNA

The D700 inherits the ‘must have’ image quality of the D3. Using the same core technologies such as the highly-sensitive 12.1 effective megapixel CMOS image sensor with large pixel pitch and gapless micro lens array that affords bright, clean files across a broad ISO range. The D700 also features the same innovative EXPEED high-speed image-processing system, 14-bit A/D conversion and 16-bit processing pipeline to provide the detail and smooth gradation necessary for outstanding print enlargement and reproduction.

FX on the move

The D700 is ideal for those seeking a perfectly-balanced DSLR on the move, without compromising durability or environmental resistance to moisture and dust. The D700 incorporates an image sensor cleaning system that uses high frequency vibrations to reduce the accumulation of dust on the image sensor surface. A responsive 5fps is possible with the compact 1500mAh EN-EL3e lithium-ion battery, with up to 8 fps possible by attaching the optional MB-D10 battery pack to use the powerful 2500mAh EN-EL4a battery if desired. This offers complete power supply integration for those already using the D3 and D300. Another first is the practical i-TTL built-in pop up flash with 24mm lens coverage, ideal for discrete flash lighting when a full size Speedlight might be too cumbersome.

Getting the shot right

Despite its attractive price tag, the D700 makes no compromises in its comprehensive feature array with a highly responsive shutter release time lag of just 40ms, the acclaimed accuracy of the 51-point MultiCAM3500 AF system, DX Crop Mode and Live View with contrast-detect AF displayed on the same high-definition 3-inch TFT monitor used on the D3 and D300. One of the most important advantages of FX format cameras is the viewfinder experience and the D700 features an outstanding solid glass pentaprism, 95% coverage and adjustable AF point LED illumination for a bright, uninterrupted view. A clever new feature is the ability to display the Virtual Horizon level indicator during Live View mode to determine camera orientation at arms length.

What NIKKORS have been waiting for

The D700 is designed for the future without ignoring the past. As Nikon celebrates the 75th anniversary of the very first NIKKOR lens, and with well over 40 million sold, intelligent image processing technologies to control peripheral illumination (Vignette) and chromatic aberration enable photographers to rediscover the creative possibilities of their existing NIKKOR F mount lenses. For newcomers, the ever-expanding Nikon Total Imaging System provides lenses, Speedlights, Software and accessories for every photographic challenge both now and in the future
