Panasonic has settled into a habit of releasing two versions of its superzoom compact, one with high-end movie functions and one which concentrates more on everyday shooting. We love the movie-orientated, but the TZ8 is a whopping £50 cheaper at around £200, and is it really that far behind? Let's take a look.
First, the key differences between the two. The TZ10 comes with built-in GPS, whereas the TZ8 doesn't. GPS is cool when it works -- you can 'geotag' your pics so they'll always be encoded with the location they were shot -- but you can only really rely on it outdoors. How much you want it is up to you, but only real Flickr enthusiasts will probably find it anything more than a fun gimmick to show off with.
The TZ10 comes with a choice of recording movies in AVCHD Lite or regular Motion JPEG formats, whereas the TZ8 only shoots Motion JPEG. The key point here is that both cameras can shoot standard 1,280x720-pixel HD movies, and many users will opt for the Motion JPEG format anyway. AVCHD Lite is more efficient, but it comes with a complex file structure and demands compatible software and hardware. The Motion JPEG format is universal, and produces single files you can copy and launch with a double-click on your computer as easily as you open a photo.
Panasonic's over a barrel with this one. It simply had to give the TZ8 an HD movie mode, given that all its rivals now have this too, so the only video difference left between this camera and the TZ10 is a choice of movie formats. Well, almost: the TZ10 records stereo sound, while the TZ8 is mono.
Anything else? The TZ10 has a 76mm (3-inch), 460,800-pixel LCD screen, while the TZ8's is slightly smaller at 69mm (2.7-inches) and has just 230,400 pixels. The TZ10 ships with a slightly better 'HD' version of the bundled PhotofunStudio software, but it's hard to get too worked up about these differences, given the two cameras are otherwise identical.
Externally, the only differences are that the TZ8 is missing the GPS 'bump' on the top plate, the stereo mics alongside it and the movie button on the back (it replaces it with an 'E.Zoom' button).
