Off the top of my head, one of the Panasonic FZ series (FZ3, 5 or 7) has most of those criteria i.e. 12x zoom, fast f2.8 lens, good battery life, SD card for storage, auto with manual overrides for most things, macro etc.

However the flash is pretty weak on them, also the LCD/viewfinder does not 'gain up' in low light, except the FZ7.

Have a look here for the FZ3, or here for the FZ5, or here for the FZ7.

If you want a flash hotshoe you will have to go for the FZ10 upwards.

Build quality of the FZ10 is very good (I have one) so I assume the other FZs are well built too.
