The Pentax 75/500, here in a visuell widefield setup with the TeleVue Panoptic 41mm.
This Ultra-Mobile setup is packed in a 35 Liter backpack. It contains a tent s.b., a small compressed sleeping bag (filled with feathers), cooking devices and an espresso maschine ;-)
The one person tent is a very small version, which can be highly compressed. This is possible due to the silicon isolation of the very resistant fabric.
