The TZ5 is getting kind of old. There are plenty of new cameras with 10x zooms. Check out the ZS3, for example. Here's what we had to say about the TZ5 when it was released in January 2008:
With its 10x optical zoom, huge for its small frame, the Panasonic TZ5 is the brand's new best-in-class for compact superzooms. In addition to the lens, it features a 9.1 megapixel sensor paired with the new Venus IV image processing engine, which aims to significantly reduce image noise. A 28mm wide-angle lens means it's easy to get good shots of landscapes and large groups of people, and a big 3.0-inch LCD screen that adjusts to various lighting conditions makes it easy to review them. The camera does not feature any manual controls, meaning it's strictly a point and shoot affair, but Panasonic's Intelligent Auto mode makes the best of this. The icing on the cake is 720p HD video recording.
