For the past 10 years I've been carrying my camera in shoulder bags and it had been like that in jungles, mountains or city trips.
Now, as I'm reaching my 30s carrying the camera in that style is getting worse and worse. Doing city trips is not much fun any more as I feel that stinging pain on my shoulders in the evening and the day after.
This weekend was bad in particular as I joined my friend on a ski tour in the alps (5h) and carrying that bag was draining my stamina to a point where it's just not tolerable any more. After removing all the filters and whatever I had in that bag it shouldn't be more than 1,5kg - still it felt unbearable after 4h ascent.
Having a camera-rucksack is not really an alternative as I'm skilled with fetching the camera (I'm wearing it under my back or slightly half on my hips, already knowing where I find what without looking).
Putting more weight on my hips or shoulders isn't a big deal, for most journeys I end up carrying 20-30kg and (so far) don't suffer from severe problems.
The bag I'm having is one from the higher segment and I enjoy it for most of its features (compact, my camera fits perfectly, space for filters and some notes). A Thinktank Retrospective 7 to be clear. But there's something I have to change as in spring/summer I will do tours over several days.
Any suggestions what would help?
