Really like my Zero Image but it is a 120 multi format. I use a small pelican case, (Storm actually). Worst issue I've had is if I have 120 film in it (different issue than the 4x5) and the case rubs open the shutter so I open the case and see the camera is exposing. I just try to smile and hold still for 5 seconds. Self portrait not by design.
Pretty funny about the self portrait! This could turn into a funny portfolio of images! Do you actually get any usable images?
