I'm having serious light leak problems using my old Polaroid 545 holder on a Wis ner Technical-Field with the spring back. The holder worked fine with my old Kad ak Master View (i.e. Calumet C-400) which I have since given to a friend. Is any one else familiar with this problem. Am I going to have to spring <groan> for a Grafloc back to cure this? I've tried e-mailing tech support at Wisner, and have not received a response. I am currently resorting to wrapping my focusing cloth around the rear standard, with iffy results.

Thanks in advance.
