Processing:
- Stable zippers
- Stable closure of the main compartment (metallic version)
- Robust material
- Rugged carrying strap
-. Seems reasonably to moisture or for example sand to be tight (hardness test is still pending)
Space:
I stow in your pocket my Tamron 18-270mm Nikon D5100 with screwed lens and various memory cards (extra pocket) and a couple of filters (also extra pocket). The screwed-lens camera fits perfectly in the pocket!
Conclusion:
The bag is totally convenient for travel - takes up little space and fits in everything important. For interchangeable lenses, I would buy myself a extra pocket - because you do not have so always there when you have a "universal lens".
For those who are looking for a robust and small bag as possible, I can give an unlimited purchase recommendation. You have to know that no additional interchangeable lenses fit in only.
