Although indeed only really purchased by riders like Katie who carry less robust SLR cameras as of course the padding does reduce the storage capacity. I dare say a home made Heath Robinson affair could relatively easily be made to fit other bags.
Padding aside I would also sugget a waterproof bar bag, both interms of protection from the elements plus the fact most bar bags hang from a bracket, as apposed to resting on top of a pannier rack, as such they may not transfer as much vibration through to what looks like a lovely, yet delicate camera, I can see why you want to take it
Having said all that I carry mine in the small pocket on the back of my Rack Pack. In all cases no matter how waterproof the storage I would recommend those little moisture absorbing packets that you get in shoe boxes etc, as moisture is in the air after all, plus bags can sweat a bit in the summer if you are riding through humid/showers/sunshine.

Once upon a time they were made with internal foam packing to accomodate SLR body & an assortment of lenses, though I haven't seen one advertised for a while. Like Paul I now use a digital compact - it weighs far less than the old Zenit E!
