The OM10 was the first of three amateur OM cameras, the OM10, OM20 and OM30.
The OM20 was basically an OM10 with a built in manual adapter, while the OM30 is an OM20 with focus confirmation which works with all OM lenses plus autofocus with a 35-70 zoom (can't remember the model number for this lens as I haven't got one...)
Recently picked up an OM30 for the grand total of £3. It was reportedly non-operational (the mirror was locked half up.) This is what the OM20 and OM30 do when the battery dies - think of it as an optical battery warning (Does the OM10 also do this? Haven't used one since they first came out - I hated the lack of manual shutter control.
What I want now is an OM2n/sp. And maybe an OM-NX adapter so I can use the really nice 50mm Zuiko lens that came with the OM30 (f2 version. Not quite as good as the f1.8 provided with the OM1/2.)
