What should I buy when I buy dslr?

pu1. Camera, lens, memory card
At least this is necessary

OK

pu2. It'd be nice to have a tripod besides what we talked about.
There's a lens hood that you put in front of the lens and it blocks the light coming in from the side. It's good to have this, too.
There's a filter on the lens that blocks reflection and can be used for many purposes

OK

pu3. There's something I'm missing from what I said. A bag is a must! The dslr is heavy, so if it's in the form of a backpack, it's easier to carry around
