Hi, I would say biking with a sling would be a nightmare after a while. What size bag are you looking for? You suggest overnight capable but small and lightweight? Not sure that exists

With a mid-large size mtb day pack I've put a camera ICU or a Top loader inside a specific MTB bag.
... I have done more than a few overnighters on the bike and always needed 30-40ish Liter packs to pull it off.
Sorry if my post is confusing, I do overnight trips (10 nights in the rockies was the longest I did) but my overnight bike (grinding bike as I call it) has two racks (front and back), 4 paniers (about 120L combined), straps for sleeping bag + tent over the racks, capacity for 3-5 water bottles depending on set-up - definitely not built for speed. The front rack is my concious decision to 1. balance the weight out front and back (makes it a bit sluggish over obstacles but definitely handles much better going up) and 2. eliminate the NEED to carry a backpack/handle bar bag.
A suggestions for the bikers out there, practice a little with loads on your front wheel before hitting the trails. I wiped a couple times the first time I had it because I misjudege the jump necessary to get the front over certain obstacles.
If I have anything at all, it is a camelback alone on my back but I think I will be switch that for a camera bag and put an extra one or two water bottle on the handle bar. As noted just need it big enough for a single body, 2 lenses and a table top tipod with spare batteries/SD cards. I actually think the slingshot 100AW would be big enough; but I seriously question whether the single strap would be acceptable over time... quite comfortable walking around in the store and I really like the side loading; but day 3 of a 7 day ride may be a little different. Our typical trip is 3 days in, rest a day with light day rides, then 3 days out.
A good handle bar bag may work too but I don't know any maker with a sturdy bag designed to fit over a bike's handle bar. Also, the bumps which the handlebar/front suspension takes may be unbearable even for a good bag - without me, the human suspension.
