Ultra-wide with a Zero
Hmmm ... I have used the Zero Image 4x5 @ 25mm and find the images quite pleasing with Velvia. Although there is some light fall-off, I suspect one just has to understand how the camera makes the wide-angle exposure and plan accordingly. Not easy, but this is the wonderful thought provoking challenge of pinhole imaging, i.e., the joys of anticipation via experimentation.
