I have seen the Wanderlust Travelwide promotions before.
For me if I was to go to all the effort of loading sheet film for a large format camera I would want to have all the movements of a bellows camera.
The Wanderlust Travelwide is a sort of large format Box Brownie with a nice lens.
The image quality would have all the advantages of the format size, but miss out on what sets the large format experience apart from fixed focal plane cameras.
