I have the same camera and so far just the 3 kit lenses that came in my package, a mid-range wireless flash, filter, reflector stuff like that and I love this camera. It becomes easy to adjust the depth of field once you get the hang of it (blurred background in focus subject) and, the duration of the shot to either freeze a tongue with crystal clarity or to blur it to show motion.
Edit: I did cheat however and have some camera related apps on my phone like the Depth of Field Calculator.
