I need to get back into the "tent" and try and figure the film out for sure.
The bigger issue: How is there no off-the-shelf bag that will hold just the camera body? I went to Kenmore Camera today and drug every insert/accessory pouch out and measured them. Nothing. They have the full range of F-stop ICU's on the shelf, most of the Shimoda inserts, plenty of the Tenba byob series, mindshift gear and some other brand I can't remember. Plenty are tall enough, but none are also wide enough. I then stopped at one of the bigger Fred Meyer stores and looked at soft cooler bags/luch bags. Again, nothing that made sense.
I've watched an older youtube video showing the f64 XL backpack. An 8x10 takes up 80 percent of that thing. There's another pack called the Evoc CP-35L. I've seen one person use that for 8x10 but again, the camera takes up 80-90 percent of the bag. The Evoc also retails at north of $400. In that price range, I think I would look at the F-stop 50 liter packs but that kicks us back to inserts that don't hold the camera anyway.
Do I actually hike that far away from camp/car with 8x10? I guess that's going to be what I have to figure out. If I don't "need" a few hiking essentials, the f64 would likely be fine.
I ended up buying an audio mixer carry bag from BH for my Ritter 11x14 and that seems to work well. The Ritter is a relatively compact field camera when folded. Maybe an audio mixer bag on a bare pack frame like the old Keltys?
