Looks like u already made ur choice on the camera so congrats. For the lens choice it's a very personal choice based on what type of photography u do, what's ur budget and preference in terms of canon lenses or other lenses with a converter.
I started a thread today on lenses I use for photography on my DSLRs not a wireless camera shooter but it's not any different fro. DSLRs so checkout that thread.
Also in the stickynthreads above ull find some great posts as well a series of articles that I wrote which are very useful regardless what body ur using as parameters and concepts apply to all cameras.
Congrats on ur purchase, make ur research as above before u shortlist few lenses and share those lenses before u buy so others can chime.in and advise.
