I picked up a backpack today. I wanted something small but was able to hold a travel sized tripod. I didn't think I'd end up with a bag from Roots, but I must say, its not too bad.
The backpack has 2 straps underneath for a travel sized tripod, but I'm sure if I wanted to, I could strap my 055xprob on there. It also has a loop on the side and a zippered pocket for a monopod. The other side has the same zipped pocket, but has openings for SD cards and pens. The front flap has pockets for accessories and it opens up to a bigger slot for an ipad.
This is why I like this bag, once it opens up, its basically one big space for you to configure what setup you like. It has more dividers, but I didn't need to use them all. Standard body with 70-200 attached right down the middle, with smaller dividers along the side for other lenses and accessories. Pictured is a D600 with 85mm attached, top left is a 20mm and bottom center is a 35mm. I also have my strap, p&s, GoPro and batteries, a suction cup mount and a speedlight. If it wasn't for the suction cup (for the GoPro) I could fit an even longer lens. Width may be a problem.
$80 from London Drugs. Little more than what I would have wanted to spend on a Roots bag, but it is built well and gave me everything I wanted without breaking the bank.
