The Good
The Bad
The Bottom Line
There's a lot to like about this little series of camcorders. But while the 16GB Panasonic HDC-TM80 and its similar kin, the no-internal-memory SD80 and 120GB hard-disked HS80, do provide a surprisingly full set of manual controls for the money, as with every HD model we've seen with a sub-HD resolution sensor, the video quality just disappoints. This review is based on an evaluation of the TM80.
It's fine in bright sunlight, when you're zoomed in on the subject. The video looks clean, though softer than I'd like, with edge artifacts. When you zoom out to a wider angle, though, you can tell that the low-resolution sensor simply can't resolve enough detail. And it's even noticeable played back on a big screen (such as the 47-inch Panasonic I used), which frequently obscures many of the artifacts. There's also quite a bit of aliasing (jaggies) on edges.
Exposures are very good; like all inexpensive models it blows out highlights, but without excessive fringing, and it handles backlit and other difficult scenes better than most. And while the colors aren't that accurate, they're certainly pleasing and saturated under bright conditions.
Unlike their low-cost competitors, the TM80 and company have an onboard LED video light. While it can help in some low-light scenes, you really don't want to point it toward people or they'll be seeing spots for a very long time. It also results in a not-very-attractive white balance, and you still lose a lot of detail in the scene. Without the light, the camcorder's low-light quality isn't very good. There's quite a bit of color noise and it's very soft.
And if you're looking for a dual-purpose still/video device, look elsewhere. You don't want to use this camcorder as a still camera; the photo quality doesn't even match that of a camera phone unless it's scaled down.
Performance is a mixed bag as well. On the upside, the optical image stabilization works quite well, even out to the end of the 30x zoom range. It also switches decisively, and at a nice rate, between focus subjects. Unfortunately, decisively is not the same thing as accurately; it has trouble maintaining a lock on a given subject against a busy background if the subject is even a little off-center. I also saw some odd intermediate white-balance shifts when panning (in bright light) and zooming (in dim light).

While the microphone has a nice, warm quality compared with some competing tinny-sounding models, it's a lot more front-directional than most, even without turning on the zoom mic. Normally, my running commentary stands out loud and clear; with this camcorder, it was so muffled at times I couldn't even make out what I was saying. But it still picked up plenty of ambient noise.
As with a lot of these models, the LCD is difficult to view in direct sunlight. You can jack up the LCD's power and brightness separately, but increasing the brightness just washes it out and decreases the contrast, while increasing the power burdens the battery. At least at its defaults, however, the battery seems to last a decently long time.

There's not much notable about the design; it's pretty typical for a compact camcorder. There's a three-way video/still/playback switch on the back and there are auto/manual, OIS, and power switches in the LCD recess. The lens cover has a physical switch, but can open automatically when you power on, which is a nice touch. Like most compacts, if you've got large hands you may find it a touch small. That's the primary reason to consider the HS80, because the hard drive gives you a little extra bump to grab onto.
However, if you're looking for manual features--specifically control over shutter speed and aperture--Panasonic delivers them at low price points. And the implementation works very well, despite a display that's usually too small for comfortable touch-screen use.

The camcorder also has useful features that are uncommon in lower-end models, like peaking (an edge-detection display) in manual focus, which actually makes it possible to use the manual focus on the low-resolution display.
Conclusion
I'm slightly annoyed about the naming convention here: you'd think an xx80 designation in the model name and a similar price would imply that it's a step-up or replacement model for the xx60 series, which I really liked. But thanks to the sensor, it's actually a step backward; the true replacement models are the xx90 series.
There really are better choices than this series. For many people it might be worth spending a little extra to get better video quality with the manual features; if you don't care about the manual features, you might as well go a little cheaper and get the same so-so video.
