The 12-megapixel Canon PowerShot SX20 IS improves on the well-liked PowerShot SX10 IS in a few ways, including the addition of HD video capture (720p), along with a small bump in resolution. It shares the same 20x optically stabilized zoom lens, with an impressive 28 mm wide angle, making it great for both close-ups and panoramas. While its 2.5-inch LCD is on the small side, it rotates horizontally and vertically, giving shooters greater flexibility in setting up shots. Negatives, according to reviews, are its large size (it weighs nearly 20 ounces) and its less-than-perfect performance in low light.

Review: Canon PowerShot SX20 IS, Lori Grunin, Dec. 15, 2009
The SX20 is included in ConsumerReports.org's report on digital cameras. Each camera receives a rating, but individual reviews are rather brief and you need a subscription to read them.

Initially, editors were disappointed that Canon's SX20 offered little improvement on its predecessor -- until it dropped in price, which prompted them to call it "an unbeatable all-around package."
