I personally don't like Dakine camera bags. I've found them to be very mediocre; the ones that do work don't hold anything more than basic camera gear.
Dedicated camera bags are a pain in the ass for skiing. Your best bet is to get a good BC pack and buy an F:stop ICU. That way you have room for food/water/shovel/probes/beacon/etc., and you have a cube designated for your camera.
I found a sick REI bag that has hydrophobic zippers, top and back entry (this is essential for camera gear), and tons of support straps. Only $90! Add an ICU and the total cost is around $150.
