I know of 2:
Olympus Pen (F / FT)
Was there any more?
Yes, but less classic models: the Yashica Samurai family (X3.0, X4.0, Z)
Fixed lens SLR with a zoom, autofocus, programmed exposure. The most weird form factor for a 35mm camera. Looks more like a video cam. Takes landscape oriented pictures in the normal position (actually makes it difficult to take portret orientation pictures). I have a Samurai Z and enjoy using it.
