After being on the manufacturer's website, I bought the WP-570 model recommended for the Lumix TZ10 and TZ30. I was very disappointed. In fact, the TZ10 / 30 is a small device with a big x20 zoom. At maximum zoom, the lens extends about 50 mm. Therefore, Dicapack proposes a cover with a big "cylinder" in front can hold the lens. Except that when not using the zoom, the inner edges of the cover are in the field of photo ... The photos are so horrible.
Otherwise, the settings are hard to reach because the cover is thick, and too large for the camera in my opinion (for example, the TZ30 is 60 mm high, and the cover is 120 ...) thus better is preparing a single feed setting. No worries however with the seal of the cover (tried to sea and pool)
For the Lumix TZ family, I highly recommend this product which is not at all suited to the device and far from given.
