I have and occasionally use a Brooks Veriwide, the more modern kind with removeable back. It stays home a lot because the enormous back forces me to use a large Pelican case, and that means little else will fit in my backpack... The camera is based, as I understand, on the Graflex XL and should use the same backs. I have no experience with Graflex, so- I'm wondering what options are out there for a more compact 6x9 back. I'd even consider using sheet film in the interests of bulk control, since I seldom shoot more than a handful of frames. So what is out there and exactly which pieces would I have to buy? Do I need a back adapter of some kind?
