True, but what your eyes see will be somewhat misleading.  The
focal length of the viewing lenses of a MF viewer is roughly
2x the FL of realist format viewer lenses, so the magnification
is much less.  While I really enjoy viewing MF slides, the
difference in the immersive effect is far less than one might
anticipate when comparing just the size of the chips.
