Good: 

Very affordable.
20 MP APS-C CMOS Sensor
Built in stabilization system
8fps continuous shoot mode.

Bad: 

Continuous mode shooting reduced to 5fps at full resolution.
Autofocus in low light is fleaky.
Flash amplitude is poor.

Bottom line:

The Sony A58 has a decent continuous mode shooting a 8fps making it a nice camera to shot high speed situations like sports or outdoors.
Well suited for beginners.
