Hi ddaw1 and welcome to the Q&A Board!
There are many fine camera bag manufacturer's. I recently purchased a Lowepro back and am very pleased with it as to features and quality. I love the all weather cover ... neatly tucked away within the bag for times I may need it.
Lowepro offers a line camera bags that is specifically geared for digital cameras. You may can visit their website to see what they have to offer and where you can purchase them.
Check out the Alternate Views links to get an idea of how a camera will fit in a bag. Also click the Specifications link. It lists dimensions, capacity and types and numbers of accessories the bag will hold.
