For the most part, new models using AAs are either entry-level compacts or larger megazooms where you already have a bigger body because of the lens. If you're looking for something in between, you're options are slim--but there are options. What follows is a breakdown by manufacturer of what's currently being offered. Some of them are on their way out, though (such as the Canon PowerShot SD1100 IS pictured), so if you see something you like, you might want to jump on it.
CNET didn't review it, but a look at user reviews on Amazon turns up more positive than negative, which makes it even sadder that Panasonic doesn't have a newer version in its lineup.
For $279.95 (and it can be had for much less), the 12-megapixel L110 has a high-resolution 3-inch LCD, has a 720p HD-quality movie mode, a built-in stereo microphone, and use of the optical zoom and autofocus while shooting video. The package even includes four, AA lithium batteries for 840 shots or 7 hours of video.
The L22 is just a basic 12-megapixel camera with 3.6x zoom lens, a 3-inch LCD, and electronic image stabilization. Versions in black, red, blue, and silver are available for $129.95.
If you're just after something to slip in your pocket, check out the FinePix AV100 and AX200. Both are 12-megapixel compacts with 2.7-inch LCDs and feature 720p HD movie capture. But the $109.95 AX200 has a wide-angle lens with a 5x zoom to the $99.95 AV100's standard 3x zoom.
If you don't want a megazoom lens, but still want AA batteries, Olympus gives you one entry-level compact option, the FE-47. It's a 14-megapixel point-and-shoot with a 5x zoom lens and 2.7-inch LCD for $119.99. And thankfully, Olympus dropped xD cards for storage; the 2010 models take SD/SDHC memory cards.
The company makes one other AA-battery camera, the Optio E90, a nice-looking 10-megapixel compact with a 2.7-inch LCD and a 3x f2.9-5.2 32-96mm-equivalent lens. It sells for about $100.
For $40 more, though, you can get the EasyShare Z915, a 10x compact megazoom with manual controls as well as a fairly reliable auto mode. Of course, if you want to zoom even more, Kodak's Z981 goes out to 26x. (It replaces 2009's Z980.)
For those looking for more shooting features, you'll have to jump up to Canon's advanced PowerShots, the 10x zoom SX120 IS and the 20x zoom SX20 IS.
