I don't really notice that image is upside down.
When i see something iteresting to photograph, i frame it just on my brains and choose the lens that i know to have same field of view.
Haven't noticed my composition any better than with prism view finders or waist level finders.
I tend to do always same mistakes by composing too much by the old rules like a golden ratio (is it right term in english?).
