I THINK that you will be seeing the magnification and the 'perspective' of the 100mm lens, but not the angle of view. Most DSLRs mask off the bits where the full frame image is cropped, some show it with a line marking where the crop happens and call it a 'sports finder'. Unless they redisign the mirror and or prism and or viewfinder, the portion that is viewable is unchanged. This is why the image is smaller in DSLRs and means that the overall viewfiner image seems darker.
