Summary: The Canon PowerShot A720 IS is the flagship of the series A and has, in fact, interesting technical features, such as the 8 MP sensor, the optical stabilizer, optical zoom, Face Detection, various scene modes and a handle worthy of an SLR. Very little is known, for a change, the memory, so even in this case, better to buy an external card otherwise you will not be able to save practically nothing.
Pros: Sensor, Optical Zoom, Safety Zoom, Face Detection
Conclusion: The A720 IS comes from a long line of successful cameras and, while it is hardly the most exciting upgrade we've ever seen, it does nothing to detract from a popular and successful recipe. And this makes it quite hard not to damn the thing with faint praise because it's hard to say anything about the A720 IS beyond the fact that it's a really good little camera. Finding fault with it is a pretty awkward task.
Pros: Surprisingly good image quality (at lower ISO settings), Accurate metering in the majority of situations, Long lens with surprisingly good edge-to-edge performance, Handy macro performance at wide end of lens, Bright, clear screen, Very simple user interface, Good battery life out of NiMH AA batteries, Feels fast and responsive in use, Fairly subtle noise reduction in ISO 100-400 region, Direct print button can be customized into something useful, Comprehensive range ...
Cons: Occasional tendency to ignore (and overexpose) bright regions, Usual issues above ISO 400 due to noise and noise reduction, Low resolution screen, Rather cheap feeling plastics, Plastic tripod mount mounted on far corner of body, Battery life and flash recycle times far from class-leading (thanks to two AA cells)
Summary: The A720 IS, is incrementally superior to the A710 IS. The problem with the A720 IS, is not so much to do with the camera itself, but with the other cameras even from Canon itself in the same price bracket. The SX100 is more or less available for the same price in the market and comes with a 10X optical zoom. If any, the A720 IS’s only advantage is that of being a little more compact than the SX100 IS.
Summary: Canon recently added two models with 6x optical zoom to the top of its vast and successful 'A' series, PowerShot A650 IS and its younger sibling, the PowerShot A720 IS. The Canon PowerShot A720 IS is priced at £179.
Excerpt: When I first heard that Canon was introducing a compact point and shoot camera with a whopping 35~210 equivalent zoom, 8 megapixel sensor, optical image stabilizer, 2.5" LCD monitor as well as an optical viewfinder, all for less than $230 MSRP, well, it just sounded too good to be true so I wanted to check it out for myself. Since I've been wanting a new compact digital camera off to the store I went.
Excerpt: The Canon PowerShot A720 IS ($249) is an update to the PowerShot
A710, one of my favorite cameras from 2006. The A720 isn't a huge leap over
its predecessor, though some of the new features are appreciated.
Pros: Very good photo quality (though see issues below), Optical image stabilization, 6X zoom lens is more than typical cameras in this price range, Large 2.5" LCD, good outdoor/indoor visibility, Full manual controls, Snappy performance, for the most part, AF-assist lamp, excellent low light focusing, Well-implemented face detection, redeye reduction features, Very good movie mode allows for over an hour of continuous VGA recording, Support for conversion lenses, external ...
Cons: Noisy images in low light, even at low ISOs; highest ISO settings not very usable (in any lighting), Redeye a big problem, though it can be removed in playback mode, Mediocre LCD resolution, Sluggish flash recharge speeds, Plastic tripod mount, Included 16MB memory card is too small
Conclusion: For around $225 USD, this is a solid-yet-not-great camera. Christmas didn’t come early so you can’t expect a camera for this price to have the response and low-noise capability of a $1,000 D-SLR! If you can spare the extra money, I’d still go the SD870 IS but a hundred bucks is still 30 gallons of gas. The PowerShot A720 IS is a fine performer outdoors but has its faults in low light and it is a little pokey when you use the flash.
Pros: 8MP; 6x zoom with Optical Image Stabilization
Excerpt: The Canon Powershot A720 IS came onto the scene late this summer to replace its popular predecessor, the A710 IS. This time around, the A720 IS still sports a 6x optical zoom, an increase in resolution ( to 8 megapixels), similar 2.5 inch LCD, and new imaging processor, the DIGIC III. Also like its predecessor, the A720 IS is powered by AA batteries - the signature of the Canon Powershot A line.
Pros: Excellent image quality, Has an optical viewfinder, Stabilized, 6x optical zoom lens, Good battery life with high capacity rechargeables
Cons: Poor flash cycle time, Low pixel count in LCD (115K), Plastic construction doesn't inspire confidence in durability, High ISO shots are noisy (which is pretty typical in this class), Low light performance not great
