If you can find a decent-sized soft case that holds it and accommodates a vertical strap, keep it at the base of your shoulder strap, where it connects to the pack bag.

I do this with more compact cameras, and it's the best place I've found for quick access and not getting in the way.

The S3's pretty big, so finding the right case is no small challenge.

Quote:
I have a fairly heavy camera, a Canon S3 with the 14x zoom. The problem is carrying it with comfort.

1. in my pack: well it takes a lot of time and effort to get it out... and for wildlife... it is usually long gone
2. on the hip belt of my Jam 2: it actually slides down and unhooks the hip belt!
3. on my pants belt: it drags my pants down after a while.
4. on my sternum strap: ok I feel like an idiot with a big camera bag just below my chin

Any ideas?
