Summary: I used the A390 for several months as a second, backup body. It has a good sensor (similar or maybe same as the A550/A560?), ergonomics could be better though - unless you have very small hands. I did not like the lcd display (low resolution) and the bronze-age user interface - same as on the A230. It did its job as a secondary body - the small, plasticky body was not a problem, but some features were missing and I traded it for a A55.
