Wade flexure may or maynot be a problem I need more info or a picture 
showing how the Pentax 67 is attached to the 155EDF.

When I attach my 67 I use a losmandy camera bracket than a losmandy ring 
on the front of the lens.

To find out how the Pentaxs 67 lenses convert to 35mm the easy way is 
just divide the lens mm number in half. 105mm in 67 = 52.5mm in 35mm. I 
didn't undestand from past posts who asked this question.
