I am looking for a bag where I can pack two cameras, several lens and a laptop to use as a carry-on bag on flights. I would also like to use it as a regular camera bag on interviews when I have to dress up and head downtown. This is what I'm thinking of buying. I tried posting it as a live link but photo.net just makes it too damn complicated. http://www.lowepro.com/Products/Shoulder_Bags/notebook_camera/Stealth_Reporter_650_AW.aspx
The Stealth Reporter 650 is a very large, lightly padded bag, but probably not large enough for two pro SLRs. I considered this bag, but opted for a LowePro Magnum AW - more room, better padding, slots for two SLRs and less digging around for gear. I now carry a Computrekker AW with two bodies, three f/2.8 zooms and gear. It's cleaner than a hiking-type backpack, and all black. I'm not embarrassed to be seen as a photographer - the camera is a dead give-away.
I have that bag, but not two bodies. I carry my 20D, 3 580EX flashes, Epson P2000, Custom Bracket's CB Junior, 17-40L with hood, 85mm 1.8, 50mm 1.8, Canon TTL cord, OmniBounce, Flash softbox, spare batteries, Large Bulb Blower, spare batteries, charger, etc. I still have some more room for a couple other things. I could probably fit my 70-200 4L as well if I wanted as I could just move the TTL Cord and Stofen to another corner. That being said, I would say two 20D sized camera should fit fine. If you really want, I could take a pic, but... -Mario
