Canon unveils EOS 500D/ Rebel T1i DSLR—Technologies Explained

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 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.

• Reduce – Internal camera mechanisms are designed to minimise dust generation. The redesigned body cap prevents dust generation through wear on the cap itself.
• 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.
• 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.

Clear View LCD
Canon’s Clear View LCD screens are 3.0” in diameter and feature a VGA (640×480) pixel resolution with 920,000 dots. This allows high-quality viewing of images and ultra-accurate focus checks in playback. Thanks to a wide 170º angle-of-view, a Clear View LCD can be viewed in a wide range of environments with ghosting and reflections being eliminated thanks to Canon’s unique dual layer anti reflective coating. This combination of features enables photographers to enjoy shooting from awkward angles.

Full HD
Thanks to the combination of a Canon CMOS sensor and DIGIC 4 processing, Canon is able to offer Full HD resolution movie recording in a digital SLR camera. An HDMI connection provides the ability to play back movies directly on any HDTV in high quality HD resolution. Canon’s Full HD products feature the same maximum resolution available for HDTV’s (1920×1080 pixels), ensuring outstanding clarity. Full HD exceeds the quality found in HD ready (720) resolution devices.

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:

• Standard – for crisp, vivid images that don’t require post-processing
• Portrait – optimises colour tone and saturation and weakens sharpening to achieve attractive skin tones
• Landscape – for punchier greens and blues with stronger sharpening to give a crisp edge to mountain, tree and building outlines
• Neutral – ideal for post-processing
• Faithful – adjusts colour to match the subject colour when shot under a colour temperature of 5200K
• 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.

Recently added functions to Digital Photo Professional include a Peripheral Illumination Correction tool, which reduces the darkening that can occur in the corners of images shot with certain lenses. The Lens Aberration correction tool allows precise correction of different types of distortion caused by certain cameras. Users can also control the highlights and shadows within an image, reducing the problem of ‘clipped’ areas where detail is lost.

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.

ZoomBrowser/ImageBrowser
For extra-easy review, editing and management of JPEG files, two pieces of software are included: ZoomBrowser for PC, and ImageBrowser for Mac.

Both programs feature a MovieEdit function plug-in, which supports the .MOV clips recorded by the EOS 500D and EOS 5D Mark II. Users can use this to perform basic editing tasks, including creating and exporting clips which combine movie files and JPEGs.

*A built-in HDMI connection allows easy and instant review of images and movie clips on any compatible HDTV.
*Figure may vary depending on capacity of SD card used

Canon EOS 550D digital camera specifications

Owners opinions:

Canon EOS 550D (Rebel T2i / Kiss Digital X 4) review in-depth April 2010

The Canon EOS 550D is difficult to categorize. Seemingly designed to appeal to buyers DSLR for the first time and enthusiasts, it offers much more technology, and at a higher price, we could expect a camera aimed squarely at this sector. Although it may seem logical to the 550D to replace the 500D EOS, the oldest aircraft is called to continue in the rangeof Canon, leaving the 550D stuck between his entry (represented by the rest of current EOS 1000D and 500D) and nominally Enthusiast (EOS 50D peers). Be misleading, however, outside of the quality of construction (which is all but identical to the 500D EOS), the 550D has more in common with the semi-professional EOS d, and – perhaps even more be confusing – is – in specifies the 50D EOS in many areas                                                             

Central to the impressive specifications of the 550D EOS is a mode video high-Spec, which offers a

full range of HD ca

pture up to 30 fps, manual control of exposure, and the ability to use an external

microphone. New camera also inherits EOS d is a sophisticated measurement system of the (which provides much closer to same placed Nikon SLR). Then why Canon has seemingly risky cannibaliser man by releasing such a specced-even the end of the lower model sales? Well, Canon could have invented the "entry level" way DSLR in 2003 with the attractive price (for the moment) EOS 300D, but these days, this sector of the market is quite busy. Far from enjoying a monopoly, Canon, as all manufacturers face a battle hard to make its products stand among many peers. To this end, Canon has left the game with the 550D EOS and produces the rebel more highly specced we have ever seen. Now that the production of an extract arrived at dpreview offices, we had the chance to submit it to our complete test procedure in depth. Read on to see how it behaves.
