Conclusion: The Canon PowerShot SD780 IS Digital ELPH aka Digital IXUS 100 is a stylish, small digital camera that has high-resolution, a HD movie mode and optical viewfinder. As you can probably tell, the SD780 won’t have any problems fitting into even the smallest of pockets, purses or bag compartments.

Summary: Canon has taken the concept of a fashionable, easy-to-use point-and-shoot that also performs well and knocked it out of the park. The Canon PowerShot SD780 IS is sure to turn heads and keep casual photographers happy with its image quality and fun features. It's the best-looking point-and-shoot camera we've seen in 2009, and it's one of the best basic point-and-shoots, period.
Summary: In most regards, the $279 Canon PowerShot SD780 IS is a solid mid-range point-and-shoot: it has decent image quality, records HD video, and is one of the most attractive pocket cameras we've seen in a while. Some flaws, however, such as overexposed shots when using Macro and low-light performance, hold it back from a higher rating. But casual photographers might rather have a camera this tiny than one that excels at close-ups or low-light shooting.
