Canon PowerShot A650 IS and A720 IS
Thursday, August 23rd, 2007After months of rumors, Canon’s big announcement day has finally arrived, with a raft of new PowerShot and EOS models and a handful of new accessories, We start with a couple of additions to the popular ‘A’ range of affordable digital compacts, the PowerShot A650 IS and PowerShot A720 IS, replacing the A640 and A710 IS respectively. The A650 IS boasts 12MP resolution, 6x optical zoom, vari-angle 2.5" screen and – in a welcome upgrade to the A640 IS – image stabilization. The A720 IS is a less dramatic upgrade, increasing resolution to 8.0MP, adding face detection and an optional underwater housing, and (like the A650 IS) upping the top sensitivity setting to ISO 1600.
Press Release (European):
Advanced photography for all: the PowerShot A650 IS and PowerShot A720 IS
Amstelveen, The Netherlands, 20 August, 2007 – Canon today strengthens its PowerShot A-Series range with two feature-packed new models. The elegant PowerShot A650 IS offers a range-leading 12.1 Megapixel CCD, 6x optical zoom lens and a 2.5” vari-angle LCD, while the compact PowerShot A720 IS combines an 8.0 Megapixel CCD with a 6x optical zoom lens. Equipped with optical Image Stabilizer technology1 and advanced high ISO capabilities, both cameras offer a comprehensive solution to image blur.

Go further with PowerShot
With resolutions of 8.0 and 12.1 Megapixels respectively, the PowerShot A720 IS and A650 IS give users the power to create poster-size prints or crop sections of photos without loss of detail. The 6x optical zoom lenses on both cameras benefit from Canon’s 70-year heritage in optics with a range of leading technologies. Aspherical lens elements ensure maximum sharpness and clarity throughout the zoom range, while the lens-shift type optical Image Stabilizer (IS) combats blur without affecting image quality.
Users can take zooming further with the incorporated Digital Tele-Converter and Safety Zoom – offering all the benefits of digital zoom without the danger of interpolation. Both models can be supplemented with Canon’s range of converter lenses, including Close-up (A720 IS only), Tele Converter and Wide Converter lenses (both models). The PowerShot A650 IS also features Canon’s improved Image Inspection Tool, which allows users to quickly check key parts of an image at extra-high magnification on the integrated 2.5’’ LCD.
DIGIC III: the power behind great photos
As well as assuring fast performance, superior colour reproduction and accurate white balance in both models, Canon’s DIGIC III processor powers a range of features designed to assist photographers of all levels. Advanced Noise Reduction Technology safeguards images against graininess, even at high ISO speeds. Face Detection AF/AE/FE locates up to 9 faces in any scene before optimising focus, exposure and flash for perfect people shots. And for flash shots affected by red-eye, improved Red-Eye Correction during playback is included. This innovative system uses Face Detection Technology to identify faces and correct red-eye in captured images – while ensuring that no other part of the image is affected in the process. Red-eye correction can also be performed manually if needed.
Anti-blur features
A combination of technologies allows the PowerShot A650 IS and A720 IS to produce great shots with minimal risk of image blur.
Both cameras feature Canon’s optical Image Stabilizer, first developed for Canon’s professional EF lenses for the world-leading EOS SLR photography system. The optical Image Stabilizer uses lens-shift technology to counteract the effects of camera shake. As a second line of defence against camera shake, the PowerShot A650 IS also incorporates Auto ISO Shift, a manually selected feature that boosts ISO just enough to avoid blur. A range of high ISO features avoid the blur caused by subject movement, as well as camera shake when low light would normally require a longer exposure. Both cameras feature user-selected settings up to ISO 1600 and High ISO Auto, which prioritises high ISO settings for better low light snapshots. For particularly dark conditions, the PowerShot A650 IS incorporates a special ISO 3200 scene mode, which captures images at 1600×1200 resolution – perfect for postcard size prints.
Total versatility
With 19 and 21 different shooting modes respectively, the PowerShot A720 IS and A650 IS ensure that novice users can get great results with minimal effort – even in situations with tricky lighting. For more experienced photographers, full manual control offers wide scope for experimentation. Both models also incorporate Canon’s My Colors, which can be used to apply effects and enhancements during shooting. A new Image Resize function users can downsize full-resolution images to 1600×1200, 640×480 and 320×240 sizes. This is equally useful for conserving storage space or preparing images for email or the Web.
Movie moments
With both the PowerShot A650 IS and A720 IS, users can capture their memories in smooth 30fps VGA movies with sound – either in standard mode or a new LP (Long Play) mode, which offers movies of half the file size without compromising on resolution or frame rate.

Technologies Explained
DIGIC III
Canon’s DIGIC III (DIGital Imaging Core) image processor manages all of the camera’s primary functions to optimize operating efficiency. Advanced image processing algorithms deliver superb image detail and colour reproduction with accurate white balance. High-speed processing results in outstanding responsiveness, rapid auto focus and extended continuous shooting ability. DIGIC III also powers advanced Noise Reduction Technology and Face Detection AF/AE/FE.
Face Detection AF/AE/FE
Canon’s Face Detection AF/AE/FE system automatically detects up to nine faces within a frame before adjusting the focus, exposure and flash to ensure optimal results. It is able to determine which faces are intended to be the subject, instantly reverting to the partnering 9-point AiAF system if no face is the primary subject.
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.
Optical Image Stabilizer
Both the PowerShot A650 IS and A720 IS use a lens shift-type Image Stabilizer (IS) system to detect and correct slight camera shakes that can cause image blur. Minute vibration gyros detect lens tilting caused by hand shake. These signals – 4,000 per second – are processed by a single-chip IS controller, which discriminates between hand shake and intentional camera movements. Shake signals are sent to the IS unit, which moves one of the lens elements accordingly to deflect the light rays and cancel out the effects of shake. For improved accuracy and responsiveness, the moving lens element is supported on tiny ceramic spheres. In addition to minimising friction, ceramic spheres avoid some of the problems that can affect metal systems, such as thermal expansion and magnetism. The optical IS of both models allows photographers to shoot at shutter speeds up to 3 stops slower with no perceptible increase in image blur due to camera shake.
Digital Tele-Converter and Safety Zoom
Similar to placing an accessory lens on the front of the camera, Canon’s Digital Tele-Converter adds a constant digital zoom to every shot (A720 IS: 1.6x / 2.0x, A650 IS: 1.5x/2.0x). While optical converter lenses cause a reduction in aperture and consequently require a slower shutter speed, the Digital Tele-Converter maintains aperture size, reducing the risk of image blur.
Safety Zoom protects the image from interpolation at high levels of digital zoom, allowing users to extend zoom magnification without sacrificing image quality.
Level of Safety Zoom possible at each image size setting without loss of image quality:
| Large | Medium 1 | Medium 2 | Medium 3 | Small | |
| A650 IS | 6.0x | 7.4x | 9.3x | 15x | 24x |
| A720 IS | 6.0x | 7.6x | 9.6x | 12x | 24x |
DigitalCameraInfo has a review of the Canon PowerShot SD750 and writes, “The 3-inch LCD is awesome because of its huge previews, readable menu fonts, and beautiful picture playback. … There is more to the camera than the LCD screen, of course. It takes great pictures, and this can’t be said of all compact digital cameras. The Canon SD750 had nearly perfect color production that held up even in very dim lighting. The image quality only suffered when the ISO was hiked up, which caused a notable amount of noise. The 7.1-megapixel SD750 has a great compact body, a huge LCD, and a feature set that is included on lots of other digital cameras. I wouldn’t pay $349 for it, but it’s a great little digital camera.”
Bogen Café is a new imaging workshop environment offered to college students in the USA. Steven Katzman, a self-taught photographer, author, and professor of photography at Ringling College of Art and Design, will give an evening lecture at each workshop. Highlighting a special selection of products from Bogen Imaging and the program’s sponsors, Bogen Café will visit 20 colleges and 20 dealerships per year for the next four years, beginning August 2007.
PhotographyBLOG has a review of the Sony Cyber-shot DSC-G1 and writes, “The Sony Cyber-shot DSC-G1’s image quality is slightly above average. The Sony Cyber-shot DSC-G1’s main drawback in terms of image quality is noise, with ISO 400 showing obvious noise and blurring of detail. The noise gets progressively worse as you go from ISO 400 to ISO 800 and finally the completely unusable 1000 setting. The noise at ISO 400 is also clearly evident in a 15×10 inch print. The Sony Cyber-shot DSC-G1 handled chromatic aberrations very well indeed, with limited purple fringing effects appearing only in high contrast situations.”
