I am looking for a camera bag that allows me easy access to my equipment and gives me the ability to store my camera with the either lens attached. I have a Nikon D50, a Nikkor 28-80mm Lens, a Sigma 70-300mm lens, and plan on getting a flash some day. I have my bag selection narrowed down to a Tamrac Velocity 7 or a Lowepro Slingshot 100. I really like the features of the Slingshot but I am not sure if the camera will fit with the Sigma lens attached. Any input is greatly appreciated.

If you plan to go with the Velocity 7, I'd recommend the Velocity 8 or 9. I have the 7 and it's a tight fit for my Oly E-500, 14-54mm, 50-200mm and the Fl-36 flash. I wish I went bigger.
