If anyone is looking for an easy to carry and use camera bag for a 4x5 field camera, I would recommend one of
these
I recently bought mine from Amazon and used it last week for the first time in the field and for me it's worth its weight in gold. So easy and comfortable to carry. I was able to retrieve my Ebony SW45 from the bag without having to take the bag off my shoulder. Great if you're working in wet/dirty locations.
The bag is big enough for me to carry camera + lens attached + another lens, light meter, cleaning kit and up to 10 DDS in their pouches. There are pocket spaces for note-book, pen, cable releases, etc.
There is a very welcome rain cover tucked in the base of the bag.
All in all a well designed camera bag that is not over big - well done and thank you Lowepro
