Lowepro Fastpack 200 how big?

[Nixtoo]

Hi,

I've waiting for this bag to arrive (free with mag subs) I've seen contradicting info on what it'll hold. The mag said camera + lens and upto 3 other lens and a flash. But the lowepro site says it will hold much less. Does anyone have one of these? I'm hoping to fit in it a 400d and kit, sigma 10-22, canon 55-150, niffty and flash (once I've got them all :))

Thanks
Nix
