Moving ever so slowly from my little-used Hasselblad toward a Fuji 645Zi. I've searched APUG's relevant posts, but I need a verification on item. One poster mentioned that the Fuji 645 negatives or oriented vertically--meaning, I take it, that the wide dimension is not oriented horizontally, as in a 35mm. Is this the case? (that would be a deal breaker). And the Pentax 645?--same story?
