In the manual, it hints at terrible, but unspecified, catastrophes that will surely result. Didn't make sense at the time either but I wasn't about to try and then says oops and hope for the warranty to cover it. Even a film M has enough bits and bobs that one shouldn't mount a collapsible lens unless it is extended.
