Hi Bernard. I should have mentioned, I really can't use shoulder bags. I have a Lowe-Pro stealth, but the weight on my shoulder (mostly left) is painful. For actually shooting I am going to use a Kinesis belt with a harness. Chances are I will move my clothing in a roller case. I think two weeks worth of clothing is going to weigh a lot more than my gear.
Which day pack do you use with your ZD?
That depends on the kind of trip I am up to.
- When I am backpacking without a base camp, I use a super light (200 gr.) Millet foldable bag to carry my valuable items on the plane. there is no waist belt though, so it can feel heavy on the shoulders. Besides Millet, I believe that at least The North Face sell similar light foldable bags,
- When I am shooting around a given area (and weight is less of an issue) with day trips only, I use an Osprey day pack.
Either way, these are just coming on top of a large backpack. I personnally like Osprey products for various reasons, but other brands do nice stuff too.
