Panasonic Lumix DMC-TS4 Digital Camera Review$399.99
Hopefully you'll be doing all your shooting in bright daylight, because at ISO 100 noise rates are quite impressive: only 0.67% on average. After that, noise rates immediately cross 1.00% at ISO 200, increase to 1.21% at ISO 400, and remain steady there as noise reduction software attempts to compensate. The technique is quite aggressive and results in very grainy shots at 1600, the maximum sensitivity level.
This isn't a strong low light camera, but it doesn't have to be, right? Stick to outdoor shooting and you won't have any problems here. More on how we test noise.
The ISO spectrum is modest, extending from 100 to 1600, and again, this limitation is in keeping with the camera's intended use. A High Sensitivity scene mode is available, and this ups maximum ISO to 6400 at the expense of resolution.
