Lowepro CompuTrekker AW Camera Backpack I've only had it out of the box for a few mins and quickly transferred over the stuff from my Flipside 200. This thing is massive, but small at the same time. I'm so glad the 50D fits. The quality on this bag appears to be top notch. Will be doing a photo shoot Saturday and Sunday so i'll be able to better judge how it feels on the back and working with it.
