Summary: The Sony Alpha 390 isn't a bad camera, but there are so many better options on the market that it is hard to recommend. Ultimately, so little has changed, compared to its predecessor, that its specifications and performance now look very out of date.
Pros: Good RAW resolution, Reliable metering (most of the time - see 'cons'), Fastest AF in live view among 'traditional' DSLRs (but see disadvantages below), Coherent ergonomics for live view operation, Much improved handgrip over A380 (but still less comfortable than A350), Probably the easiest DSLR ...
Cons: Soft JPEGs at all ISO settings, High ISO performance not on the same level as direct competitors, Smallest viewfinder of any APS-C DSLR, Protruding screen obstructs use of viewfinder, especially if you're wearing glasses, Limited external controls, No on-screen user interface for changing of shoo...
Sony's DSLR-A390 captures clear and vibrant images, but doesn't feel good to use

Conclusion: Sony's DLSR-A390 is capable of capturing vibrant and clear images, but its body could use some work. For starters, we'd like a dedicated button for the flash and for zooming in on photos in playback mode, and it's awkward to change the aperture in manual mode. The camera also lacks video mode.
Pros: Good clarity, vibrant images, menu system provides helpful hints, uses SD in addition to Memory Stick Pro Duo, ships with good quality 55-200mm lens, good Live View implementation
Cons: Feels uncomfortable, needs more and better placed buttons, no video mode
