It depends on how big the obstruction is. I know someone who ruined his 5Dmk2's mirror with a Rollei lens, where I believe the mirror must have struck the rear of the lens when going up. With the Contax lenses are known to cause mirror problems, the 5D's mirror usually only hangs when going down, after the exposure, which isn't really harmful.
