Just playing with my new ebony 45s and getting used to focussing with axis symmetrical tilt for the first time, my previous camera had base tilts only.
I noticed that my Wista lens board has an off-centered hole so the lens does not tilt right on axis. I'm finding that the area just below center of the frame is maintaining focus during the tilt and not the center of the frame as I had understood would be the case with axis tilts. I guess this is due to the off center hole on the panel, this raises two questions.
1. Why do some panels have off-centered holes? I'm guessing to allow for more fall movement.
2. How exactly does the off-centered hole affect my axis tilt? It made me wonder if I could orient the panel upside down so the lens is above the axis tilt and thereby simulate asymmetrical tilt. I assume asymmetrical tilt works by having the lens above the axis tilt mechanism or have I misunderstood?
