It's not clear to me what path you are on, but whatver it is, the camera you own has nothing to do with it. If you want to direct, write something amazing and find a great student DP to execute. If you want to DP, assist a great DP and do the best job ever. OR work in a rental house, and on your day off (after a few months working there) you can play with all the cool toys you ever dreamed of.
The director is an old friend of mine and staying at my house while she is in nyc for the film festival. Any more questions for her let me know :) I was so excited for her to get into tribeca! I shot her first movie on a Canon XL-1 ages ago.
