IMO, since this is ur first DSLR, its good to maximise the use of the given kitlens to learn as much as you can.
no point thinking of all the great lenses out there and forgo the theories.
Equipment is 30%. Knowledge and theory is 30% and talent is 40%
u have equipment and talent u pass. but hw much talent you have is one thing.
so.. play safe. Have good knowledge on the theories. have equipment and some talent. and u passed at least.
