it is said that if you use a 50mm lens made for a full frame camera that you get about 75 mm on a asp-c sensor. can anyone tell me what you get if you use a 90mm 67 lens on a 645 sensor?

With the Pentax 6x7 adaptor on the 645 you get about a 108mm equivalent. (+20% because the adaptor moves the lens away from the body 1.5cm compared to the 645 lens.) Thats what I was told by Pentax about 25 years ago.
