Widescreen (16:9) recording
The PowerShot S3 IS caters for serious photo enthusiasts seeking extended zooming flexibility and fully featured movie recording in a versatile compact digital stills camera.
Optics
Still the most powerful zoom in a Canon digital compact camera (36 – 432mm f/2.7-f.3.5), the PowerShot S3 IS’s lens incorporates the same leading technologies used in Canon's professional EF lenses. An Ultra-Sonic Motor (USM) drives rapid and near-silent zoom operation; an Ultra-low Dispersion (UD) lens element significantly reduces chromatic aberration in telephoto shots; Canon's optical Image Stabilizer (IS) technology counteracts camera shake to reduce image blur when shooting stills or recording video, essential for handheld shots at longer focal lengths. IS allows photographers to shoot at shutter speeds up to 3 stops slower for reliable flash-free photography in low light conditions.
The PowerShot S3 IS's 12x optical zoom combines with digital zoom to deliver 48x magnification for recording both stills and video. For even wider framing options, optional Wide and Tele converter lenses extend the focal length from wide 27mm to super-tele 648mm (35mm film equivalent) for an impressive 24x optical zoom. A Super Macro mode with 0cm shooting distance and optional Close-Up lens 500D (58mm) allow for detailed macro photography.
Increased ISO speed
In addition to Image Stabilization, the PowerShot S3 IS features a new High ISO Auto setting and ISO 800 to further extend the camera's low light shooting capabilities. High ISO Auto automatically sets exposure using the higher range of ISO sensitivities, enabling faster shutter speeds in low light and increased image stability at the telephoto end. A dedicated ISO button allows for easy switching between ISO sensitivities.
Movie functions
Powerful video functions make the PowerShot S3 IS far more than just a high performance digital still camera. A dedicated movie button means users do not need to switch modes to start recording, so spontaneous moments can be instantly captured in full motion. Users can record smooth 30fps VGA quality movies of up to 1GB with stereo sound, or create 60fps QVGA clips for sharp slow motion playback. The Movie mode also allows users to pre-select exposure and white balance, zoom throughout the camera's focal range and manually adjust focus while shooting. A Photo In Movie feature enables the capture of full resolution digital stills during video recording.
Creative shooting
The PowerShot S3 IS offers 20 shooting modes including full Manual mode, Aperture Priority and Shutter Speed Priority. Together with 2.3 fps continuous shooting, a new fast-shutter Sports mode with improved auto focus accuracy provides unprecedented capabilities for capturing action sports sequences. Special Scene modes – such as Night Snapshot and Snow – assist with tricky lighting conditions, while Color Accent and Color Swap modes enable dramatic colour effects to be applied to both images and movies. Canon's My Colors photo effects have been enhanced for this model, and can now be applied to images both before and after shooting.
The PowerShot S3 IS features a new Widescreen mode (2816 x 1584 recording pixels) for capturing still images in 16:9 format – perfect for viewing images on widescreen television or printing wide (10 x 20cm) photos with a SELPHY Compact Photo Printer.
Printing and other features
A new, dedicated Print menu simplifies printing of multiple images. Full PictBridge support means users can print directly to any PictBridge compatible printer without the need for a PC. New PictBridge features include the ability to print shooting data and optimise faces in portrait shots when connected to a compatible Canon PIXMA printer. The camera's ID photo and movie stills features are also available when connected to a SELPHY CP Series Printer. A handy Print/Share button allows one-touch printing and easy uploads to Windows or Mac systems.
The camera's menu system now features support for Arabic, bringing the total number of supported languages to 23.

Soft Case (DCC-90)
Compact AC Power Adapter (CA-PS700)
Battery and Charger Kit (CBK4-300)
The camera is compatible with MMC/SD cards, and comes supplied with a 16MB Canon card.
Technologies Explained
Optical Image Stabilizer
Canon's lens shift-type optical Image Stabilizer counteracts the camera shake caused by slight hand movements. Vibration sensors detect the angle and speed of movement and send this information to a processor, allowing the camera to compensate. This adds stability to hand-held, telephoto or moving shots and enables shooting at shutter speeds of up to three stops slower with no noticeable increase in image blur.
DIGIC II
Canon's purpose-built DIGIC II (DIGital Imaging Core) image processor links all primary camera functions for maximum efficiency. High-speed processing results in outstanding responsiveness, rapid auto focus and extended continuous shooting ability. Advanced image processing algorithms deliver superb image detail and colour reproduction with accurate white balance and minimal noise. DIGIC II operates efficiently to extend battery life, for longer shooting on a single charge.
iSAPS
iSAPS (Intelligent Scene Analysis based on Photographic Space) automatically optimises key camera settings before every shot. Each scene is analysed and cross-referenced against Photographic Space – a vast in-camera library of photographic data. This enables the camera to make optimal adjustments to auto exposure, auto focus and auto white balance before image capture occurs.
9-Point AiAF
Canon's 9-point AiAF (Artificial Intelligence Auto Focus) automatically scans and selects subjects from a set of nine focusing areas across the scene. This ensures accurately focused images even when subjects are not in the centre of the frame.
FlexiZone AF/AE
FlexiZone AF/AE lets users manually select the focus point from almost any point in the frame by moving the auto focus window in the viewfinder. Exposure is linked to the focus point to ensure that the chosen subject is accurately focused and exposed.
Ultra-low Dispersion (UD) lens technology
No matter how well engineered, conventional optical glass lens elements cause chromatic aberrations which can ‘soften’ images and appear in photographs as fringing around the outside edge of subjects. Canon’s Ultra-low Dispersion (UD) glass has special optical properties to successfully reduce these aberrations. Especially effective in super telephoto lenses, UD glass helps to deliver crisp, sharp, high contrast images.
Pricing and Availability
Canon’s new PowerShot S3 IS digital camera will be available in May for an estimated selling price of US$499.99.

Amstelveen, The Netherlands, 21 February 2006: Canon today releases the Digital IXUS that advanced photographers have been waiting for – the 6.0 Megapixel Digital IXUS 800 IS. Redefining the boundaries of compact camera design, the new flagship of the Digital IXUS range fits a 4x optical zoom lens and Canon's optical Image Stabilizer (IS) technology into an incredibly slender body.
Exquisitely styled with a unique 'Curvature and Stream' design, the camera incorporates a host of cutting-edge features and shooting options to satisfy the most demanding of photographers, including:
ISO 800 and optical IS for flash-free indoor shooting
Canon's DIGIC II image processor, iSAPS and 9-point AiAF
Wide viewing angle 2.5" LCD screen
16 shooting modes
My Colors photo effects
Widescreen (16:9) stills recording
30fps VGA movies
"IXUS is synonymous with distinctive style and leading technology," comments Mogens Jensen, head of Canon Consumer Imaging Europe. "The Digital IXUS 800 IS adds another dimension to the range with a new level of functionality that will thrill serious photo enthusiasts."
4x optical zoom with Image Stabilizer
Smaller, lighter camera bodies are more susceptible to camera shake from handheld shots, especially in low light situations. The Digital IXUS 800 IS employs the same optical Image Stabilizer (IS) technology used in Canon's professional EF lenses to reduce the image blur caused by camera shake. IS allows for sharper flash-free shooting by enabling photographers to shoot at shutter speeds up to 3 stops slower. It also allows for steadier macro shooting when using the camera's 2cm Macro mode. To incorporate this technology into such a compact space, a new IS processor chip was developed by Canon's engineering team. The new chip accurately controls the movement of lens elements, delivers fast, precise shake correction – processing up to 4000 signals per second – and contributes to lower power consumption.
The 4x optical zoom lens incorporates an Ultra-High Refractive Index Aspherical (UA) lens to achieve a focal length range of 35-140mm (35mm equivalent) while allowing the camera to maintain a slender profile. The camera retains a real-image optical viewfinder despite its compact size, enabling users to frame without the LCD and further extend the camera's impressive 240-shot battery capacity.
Increased ISO speed
The Digital IXUS 800 IS incorporates ISO 800 to facilitate flash-free shooting indoors - ideal in low-light environments where the use of flash is not desirable or appropriate, such as churches and concerts. A new High ISO Auto setting automatically sets exposure using the higher range of ISO sensitivities, prioritising faster shutter speeds to avoid blur from camera shake or moving subjects.
New design
In keeping with its status as a new class of IXUS, the Digital IXUS 800 IS has a resolutely unique appearance that sets it apart from its predecessors. In an evolution of the Perpetual Curve design found on the Digital IXUS 750, the camera's elegant contours are accentuated by a striking tri-coloured design – 'ice metal' silver and 'moonlight' silver in satin and glossy finishes, complemented by an ebony black gloss surrounding the LCD screen. Designer Kosei Takahashi has dubbed his concept 'Curvature and Stream', a reference to the elliptic curves of each coloured segment and the bold, flowing lines that appear where segments meet.
The large 2.5" LCD screen gracing the back of the camera features a wide viewing angle for easy sharing of images. A selectable Grid Line Display helps with image composition, while Night Display aids screen visibility after dark. The camera's mode dial is embedded into the body of the camera, leaving thumb space clear for an easier grip.
Creative shooting
Canon's My Colors photo effects can now be applied to images both before and after shooting, offering users more opportunities to customise their creations without having to connect to a PC. The Digital IXUS 800 IS offers 16 shooting modes including Manual mode. Preset scene modes assist with tricky lighting conditions, including an Underwater mode for shooting underwater with the optional Waterproof Case. Color Accent and Color Swap modes enable dramatic colour effects to be applied to both images and movies.
A new Widescreen recording mode (2816 x 1584 recording pixels) allows for still image capturing in 16:9 format – perfect for viewing images on widescreen television or printing wide photos with a SELPHY CP series Compact Photo Printer.
The camera's powerful movie features enable recording of 30fps VGA movie clips of up to 1GB . A 60fps QVGA mode is ideal for recording fast action sequences and analysing them in slow motion, while the handy Compact mode records up to 3 minutes of footage in low resolution for easy sharing via email.
Printing and other new features
A new Print menu simplifies printing of multiple images. Full PictBridge support means users can print directly to any PictBridge compatible printer without the need for a PC. The camera's ID photo and movie stills features are also available when connected to a SELPHY CP Compact Photo Printer. A Print/Share button allows one-touch printing and easy uploads to Windows or Mac systems.
The camera's menu system now features support for Arabic, bringing the total number of supported languages to 23.
Optional Accessories
An optional Waterproof Case (WP-DC5) allows users to bring the camera to a depth of up to 40 metres for compelling underwater shots. Specially designed Weights (WW-DC1) are available to control camera buoyancy.
Other accessories include:
High Power Flash HF-DC1
Soft Leather Case (DCC-70)
Digital IXUS Metal and Leather Neck Straps
Compact AC Power Adapter (ACK-DC30)
The camera is compatible with MMC/SD cards, and comes supplied with a 16MB Canon memory card.

It allows photographers to shoot at shutter speeds up to 3 stops slower with no perceptible increase in image blur. IS is extremely helpful in low light situations, at full zoom and when shooting macro photography.
Ultra-High Refractive Index Aspherical (UA) lens technology
Canon's UA lens was the world's first ultra-high refractive index glass moulded aspherical lens. Made from glass with a higher refractive index than other aspherical lenses, it allows for an exceptionally slim and compact lens unit. The glass moulded aspherical shape delivers remarkable image quality and avoids the image aberrations that can occur with spherical lens designs.
The PowerShot SD700 IS Digital ELPH camera will be available in April for an estimated selling price of US$499.99.

Pre-PMA 2006: Canon has today announced an interesting new constant aperture 'digital' (EF-S) lens. The new EF-S 17 - 55 mm F2.8 IS is designed specifically for the dimensions of a 'cropped sensor' (1.6x crop) and hence can be made smaller than a 35 mm equivelant lens. It features a maximum aperture of F2.8 throughout the zoom range which means it's a faster alternative to other EF-S lenses. On an EOS 30D this lens would provide a 27.2 - 88 mm equivelant field of view. This lens should be available in May for approx. US$1150.
FOR 20D, 30D, 300D & 350D ONLY
Amstelveen, The Netherlands, 21 February, 2006: Canon today strengthens its EF-S lens series with the Image Stabilized wide angle EF-S 17-55mm f/2.8 IS USM. With image quality and construction approaching that of Canon’s renowned professional lenses, the EF-S 17-55mm f/2.8 IS USM becomes the fastest standard focal length zoom for EF–S mount cameras such as the new EOS 30D. Combining constant f/2.8 aperture throughout the zoom range with Canon’s latest 3-stop Image Stabilizer, it delivers outstanding wide angle performance and framing flexibility in low light conditions. Specialist optics such as UD glass and aspherical elements help deliver exceptional clarity, sharpness, contrast and colour accuracy.
EF-S mount
The lens fits exclusively on those EOS cameras with an EF–S lens mount – the new EOS 30D, EOS 350D, and earlier EOS 20D and 300D models. (see appendix ‘Technologies Explained for further information on the EF–S mount). The 1.6x multiplication effect of these cameras’ APS-C size sensor gives the lens an effective focal length of approximately 27-88mm.
Image quality
To improve image clarity over the total image area, two Ultra-Low Dispersion glass (UD) elements are employed to eliminate secondary chromatic aberrations that otherwise reduce sharpness and introduce colour fringing. To ensure crisp, high contrast from one corner of the frame to the other, two aspherical lens elements have been introduced to avoid spherical aberrations that can soften images, especially at wider apertures. In combination with digital EOS CMOS sensor and DIGIC II image processor technologies, the EF-S 17-55mm f/2.8 IS USM delivers image quality surpassing that required for many commercial applications.
Fixed f/2.8 from 17 - 55mm
Superb optical quality with no change in aperture over the full focal length range allows photographers to set exposure at the widest aperture and concentrate on framing, without concern for adjusting shutter speed at longer focal lengths. The lens employs an almost perfectly circular barrel aperture, helping create attractive, even background blur.
Image Stabilizer
The lens features Canon’s latest 3-stop Image Stabilizer (IS) for dramatically reduced image blur caused by camera shake. IS significantly extends scope for shooting in low light conditions without flash, or for gaining depth of field. The 3-stop advantage allows a photographer shooting in low light to use a shutter speed of just 1/15 sec instead of 1/125, with no perceptible increase in image blur.
IS automatically detects when the camera is mounted on a tripod, thus preventing feedback loops between the IS sensor and stabilizer motor vibrations.
(See more information on Image Stabilizer, see appendix ‘Technologies Explained’).
Fast, silent auto-focus
The lens’ USM motor employs ultrasonic frequency vibrations to drive auto focus with speed and near-silent operation. The constant torque motor moves the focus group at high speed, stopping with precision, accuracy and without overshoot the instant the lens arrives at the correct focus point. Photographers can switch to manual focus instantly and at any time simply by moving the manual focus ring without first having to switch out of auto focus mode.
Harmful reflections eliminated
By optimising Super Spectra lens coatings and lens element shaping, Canon’s engineers have been effective in suppressing flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.
EOS system integration
When used in conjunction with Canon’s range of EX Speedlite flash units and the internal flash of the EOS 350D, EOS 20D and new EOS 30D, the lens passes distance information to the E-TTL II flash algorithm to improve flash exposure metering.
An optional lens hood, made exclusively for the EF-S 17-55mm f/2.8 IS USM, and pouch are available.
In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.
Technologies Explained
EF-S lens mount
The compact APS-C size sensor of select EOS cameras such as the EOS 30D, EOS 20D, EOS 350D and EOS 300D has paved the way for a range of relatively compact and lightweight EF-S mount lenses. These lenses project a smaller image circle than would otherwise be necessary to cover a full frame sensor or a frame of 35mm film. The ‘S’ in the EF‑S nomenclature stands for the term ‘short back focus’. This describes the system that allows for both a smaller image circle and positioning of the rear lens element closer than normal to the camera’s sensor.
Cameras with an EF-S lens mount can accept both EF lenses and EF-S lenses, while EF-S lenses can only fit to cameras with an EF-S lens mount. A white lens mount index differentiates the lens from other EF lenses, which retain their traditional red marking. A rear rubber ring prevents any damage in the event that an inadvertent attempt is made to mount an EF-S lens to a camera with an EF mount.
Image Stabilizer
IS works by using gyro sensors and circuitry to detect and measure unwanted vibrations. Tiny servo motors then create corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. Unwanted movement is corrected fast enough to suppress effectively the vibrations of moving vehicles and aircraft such as helicopters.

Canon has today announced the 'Mark II' version of its (monster) professional EF 85 mm F1.2 L II lens. This new version includes improvements to auto focus speed and communication of distance information for use with the E-TTL II flash metering algorithm. This lens should be available in March for approx. US$2100.
Amstelveen, The Netherlands, 21 February, 2006: Canon today releases its latest professional L-series prime lens: the exceptionally fast EF 85mm f/1.2 II USM. With the widest aperture of any lens in the current EF range, the new model becomes Canon’s definitive portraiture lens, offering extremely fine control over depth of field and consummate low light performance. With vastly improved auto focus speed, the lens replaces the popular EF 85mm f/1.2L USM. As with all L-series lenses, the EF 85mm f/1.2 II USM incorporates the very finest standards of precision optics.
EF 85mm f/1.2 II USM - €2,049
The EF 85mm f/1.2 II USM features:
Canon’s finest standards of image quality
Latest Ultrasonic Motor (USM) for fast and near silent auto focus
Full-time electronic manual focus override
Super Spectra coatings and optimised lens element shaping to suppress flare and ghosting
Large circular aperture diaphragm for good background bokeh and ‘removal’ of distracting backgrounds
Distance information passed back to the new E-TTL II flash algorithm of all current model digital EOS cameras
Lens hood and pouch included in the box
L-series construction
The L-series is Canon’s flagship professional lens range, designed and built to meet the needs of the most demanding professional photographers. The superb optics of the EF 85mm f/1.2 II USM and other L-series lenses represent the pinnacle of optical performance, enabling focal length/speed/quality combinations not readily attainable using traditional optical technologies.
Portrait photography
The combination of an almost circular aperture diaphragm for attractive bokeh (evenly graduated blurring of out-of-focus areas) and the extremely narrow depth of field at its widest aperture combine to make this an ideal portraiture and studio lens. With the lens’ aperture at f/1.2, photographers can create dramatic effects such as keeping a model’s eye sharp while blurring the eye lash ends.
Low light shooting
The maximum f/1.2 aperture is the widest in Canon’s current range and provides for shooting in low light conditions without the need for flash or slow shutter speeds. With improved auto-focus speed from Canon’s latest Ring-type Ultrasonic Motor (USM), the lens is expected to be popular with professional photographers shooting indoor sports. The USM holds the lens with precision and accuracy, the instant it arrives at the correct focus and without overshoot, and features full-time electronic manual focus override*. Super-fine control over depth of field afforded by the lens’ large aperture allows sports photographers to deliberately ‘blur out’ crowds, hoardings and other distracting backgrounds.
Aspheric element
Wide aperture lenses using traditionally manufactured elements suffer from spherical aberration which causes an overall softening and optical ‘smearing’ of the image. To ensure high corner-to-corner sharpness and contrast of in-focus subjects throughout the focus range and at wide apertures, the
EF 85mm f/1.2 II USM incorporates a large aspherical lens element with precise variable curvature and a floating group construction.
Super Spectra coatings
In addition to optimised lens shaping to reduce reflections and the use of anti-reflective material inside the lens barrel, the EF 85mm f/1.2 II USM employs Canon’s patented Super Spectra lens element coatings. These suppress flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.
E-TTL II flash integration
The EF 85mm f/1.2 II USM transmits distance information to the E-TTL II flash system of all current model digital EOS cameras, improving flash exposure metering when used in conjunction with Canon’s range of EX Speedlite flash units.
The EF 85mm f/1.2 II USM comes with a cylindrical lens hood and lens pouch.
In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.
