they are more expensive but worth it. I have the Satori (you would not need it) and it holds:
18-55 (soon going to be a 17-40)
two canon flashes
3 pocket wizards
extra batteries (for camera, flashes, and pw)
it holds that all pretty well and I can still get all my BC gear, some food and water and extra cloths in it.
Also if your going to be hiking at all, no other packs carry as well as these do.
Also if you need to carry skis on your pack the f-stop packs are the only ones that are able to carry fat skis. in all honesty the dakine camera packs are pretty worthless compared to these. They are akward and don't carry well, can't handle fat skis and not very water proof.
For what you need I would suggest the Lotus.
the only other pack I would suggest you get is the, lowe pro Orion Trekker.
