If you are interested in some decent reading about your DSLR ... you can always consider spending several days reading and/or joining in the
SONY DSLR forum (<- click here) on the
Digital Camera Resource Page.
The forum goes all the way back to when the A100 was first introduced and covers a wide variety of issues, techniques and topics (such as "lens decisions" and camera settings). If it does not suit your fancy, fold the page and off you go.
