The Canon PowerShot A710 IS

An upgrade to the short-lived Canon PowerShot A700, the A710 IS received a design facelift and a few feature tweaks, the biggest and most welcome of which is that the new model adds optical image stabilization. In addition, upgrading from 6 mega pixel to 7 mega pixel provides for improved image quality. Is the A710 IS a worthy successor to the popular A700?

Here are the main features:

* 7.1 Megapixels
* 6x optical zoom with optical Image Stabilizer (35-210mm equiv.)
* DIGIC II, iSAPS, 9-Point AiAF, FlexiZone AF/AE
* Digital Tele-Converter and Safety Zoom
* 2.5” LCD with wide viewing angle and real-image optical viewfinder
* 20 shooting modes

What else has changed?

Although a better looking camera, the A710 IS is more than mere style, with the addition of the optical image stabilization system, the only downside of which is the slight decrease in battery life. Still, one can get an impressive 360 shots from a good pair of rechargeable AA NiMH batteries.

Additional changes include….

* 60fps (QVGA) movie mode
* MyColors effects in playback mode
* Playback overexposure warning
* 3:2 overlay on live view

Generally, users of this camera give good reviews, citing the advantages of using 2 batteries over 4, the convenience of using SD disks, date/time feature, overall quality and ease of use. Some users find that using the zoom feature indoors lowers image quality and the limits of the 1 GB file (about 8 minutes of video) and the limited storage capacity of the provided 16MB card.

The camera retails for around $300 US.
