Thanks to all for the variety of interesting viewpoints.
I want to throw a "what if " into the mix.
I want to use camera handheld at least half the time.
However, there will be times I will want/need swing&tilt. I have only once seen a 6X12 back for less than $600. I am going to look at a 6x12 Fotoman with a 58mmXl for $1K (makes the back look rather expensive).
I am trying not to paint myself into the corner of "needing" two cameras to shoot 6x12 !
Any ideas ?
