Finally made the purchase after much research. Love the quality after only some random shots indoors with the built-in Flash. Questions though. I am using the "included in package" EFS 18-55mm IS lens, and am wondering if I should grab a prime lens to help improve the pictures? And is the built-in flash good enough? Or would an external flash benefit me greatly? I know Im just starting out, but if I have the money for it now, would it make sense to get the best while I can? Thanks, and sorry if any of this sounds stupid, just being as honest as I can.
