I have a LowerPro backpack that was fitting just fine my small mirror less housing.
I now have a Panasonic GH5 with a Nauticam housing and this is taller plus it comes with integrated handles that make it too tall for the lowerpro bag
I have therefore got one of this backpacks that measures 55x40x20 and expands to 25 if needed
that are practically empty inside with the idea of fitting the bag that comes with the housing plus get another set of inserts for ports lenses etc. Obviously the whole set up would struggle with a large dome but I only have a small dome and a 6" wide angle port
The nauticam case takes almost half of the back pack but I still have space to I thought of getting one of those to fill in the rest
The positive is that the bag with the insert weights much less than the LowePro
I wonder if anyone has different solutions that minimise weight but provide maximum space?
I will post some pictures of the set up once one of my last bits arrives
