I know the IS-1, 2 and 3 use mirrors instead of a solid block pentaprism.
Keeps weight and cost down.

Subject: [OM] Mirror "Pentaprisms"
| I noticed while rummaging through the current crop of photo magazines
| is the complaint that a lot of the new plastic wonderbrick
| viewfinders have less than stellar quality because they do not have
| real pentaprisms. Its all done with mirrors (On top of fungus
| worries there will be desilvering worries?)resulting in a flat,
| uncontrasty image. The magazine advised the potential buyer to
| investigate before plunking down the money. I wonder if Oly does that
| on any of their TLR cameras.
