[Leica] IMG: Foothill Park

I guess I should have said rising/falling. 
Won't work, eh?

I have used a fixed MF back holder with my 4x5. You can, instead of using a 
sliding back, use a fixed back and shift/rise and fall the back standard. 
The fixed hoders are much less expensive. Down side is you have to remove 
the GG before putting the digi back on. Upside is that there is no wobble 
that can sometimes occur with a sliding back.
