I recently bought a new camera and the sling bag I had previously used was not big enough to carry it. I have purchased a Lowepro Camera Bag to use as a day bag. It has a zipper that allows for expansion, so on travel days I can also carry my computer and other important items. I prefer this style bag as it lays across the front of my body, and is hands free. As it is a cross body bag so deters snatch thieves.
