Exposure calculation

Would I be right in the belief that this question, and the solutions to
it,
would be applicable to formats other than "large",
should one care to do such a thing?
If the lenses you use for your 645 are attached directly to the body, and
especially if your 645 has a built in TTL meter, the answer is "no." If your
lens attaches via a bellows, and your 645 doesn't have TTL, then the answer
is "yes." The greater the extension of the lens from the body, the greater
the required exposure.
