We have performed a few tests.Rick's concerns are very valid, the main one is the lack of manual control and lack of Tiff or Raw.
To most, the JPEG /Auto settings will be fine, the keen amateur that is familiar with Photoshop and the like, will know that a cleaner image could be squizzed out from a RAW file.
The pictures we took were sharp, with a slightly higher contrast than usual ( for Pana) , well exposed and with a good white balance (on Auto), however we felt that a manual contrast and sharpness control would help.
Overall, I am happy with it because it does offer a great usable optical range ( relatively distortion free wide and tele ends), the stabilizer works as it does with their bigger models.
Not for the keen amateur/enthusiast, but definitely the one to get if you still want a long zoom range in a compact package.
Rick asked :
Any moisture or dust resistance?
Is it USB 2 capable?
Accessory lenses available for less than a king's ransom?
Not at the moment
I agree that a wider wide angle would be welcomed, but at a starting point equivalent to 35mm, it is the widest in its class. Most 10 or 12x zoom lenses start at 38mm.
We sold the first 15 in two days.
