There's a very fragile internal metal bracket on the PEN EF and in the process of trying to repair a problem on mine, i ended up breaking it. This camera is unfortunately really hard to find, and so I remade the part with my 3D printer. This is not exactly a 1:1 replacement and I can't guarantee performance or anything, but I've had it in my camera for 4 years and it's been operating just fine so far.
