OK, as no one else has posted an explanation, I'll have a go with my limited
knowledge.
In order to avoid collison with the mirror assembly a SLR wide-angle has to
incorporate a totally different design than a view-camera as the XA. The XA
has much of it's optics where an OM-camera has it's mirror mechanics.
So distance to the film is much shorter (less loss of light) on the XA.
I'm sure some other list-members can explain this in a much better way.
