Well, I have been wanting to do this for a while, and after allot of searching and thinking I bought my first DSLR this week, got a canon XTI off of eBay, brand new, the only reason I chose eBay over amazon was that there was a microsoft live rebate for about 140.00 and I already had a rebate from buying a notebook earlier this year that I could apply. So, all in all I am only out about 250.00. So, my actual questions are as follows, I think I am going to purchase an EF 50mm f/1.8, is this a smart decision. Is there some sort of lense guide that wil explain what each one does respectively. Any good reads on basic ideas behind shooting?
