Yes, I know what you mean, but my point was that your own 'normal'
focal length will vary with the combination of camera and lens that
you use. For me, with a MZ-5 and an zoom, the image in the viewfinder
is the same as the other eye at about 70mm.

This is what I meant. If you're looking at a sunset, or an open
vista, your eyes are taking in a huge field of view and almost any
lens will feel too narrow. Conversely, if you're intent on a
particular detail then your eyes change their perceived focal length
to match. What is normal to you will depend on what you're doing. I
also find the 100 (FA macro) to be a great normal lens sometimes, but
that depends on what else I've been using recently.
