Just took delivery today of the V2 Think Tank Speed Freak.
Great build quality and perfect size for my Canon 60D. It also easily holds my Canon G9, Canon 75-300 len. Will definately fit a 50mm lens when I make that purchase.
Holds both battery chargers, 3 filters and so on. Couldn't be happier.
Looked ay many bags on line and at first blush, I couldn't be happier. $159 is pricey but this bag looks like it is built superbly plus doesn't scream "Camera Bag".
