$600 is not nearly enough to build any sort of kit. I'd recommend
-
buying a fixed, zoom lens camera like a M43 panasonic/olympus for a all round use.
-
a small camera like Ricoh or Sony zv1. They don't have zoom but similar to using a phone and the small size actually means you'll carry it often.
By using either of them you'll learn your own preferences and limitations. Pro tip: buy smaller and lighter gear (cheap isn't always bad)
