People ask what I shoot with, and the honest answer is: less than you would think. One body, two lenses and a bag I can carry all day.
The wide zoom does most of the work. I use the fast prime for low light and for the days I want to slow down and look properly.
A sturdy strap, spare batteries and a lens cloth matter more than another piece of glass. Most of my best frames came from being in the right place at the right time.
Start with what you have, learn it properly and only then decide what is missing.
