How solid are the opticals inside lenses? Can they withstand a small enough of a shake before optical realignment service becomes necessary?

I would guess so, I've carried mine around in backpacks and shoulder bags where they'll 'jiggle about' whilst I'm walking/running, and I've also carried them in the panniers of my motorbike, albeit cushioned to absorb some of the impact.
 
It depends on how well the optics are made.

NASA use Nikons because they say they are confident they won't fall to bits.

I have seen photos of Nikons with big lenses on just floating around inside the ISS.

Canon? Ner we don't touch em.:cool:

Drop em from chest height onto a hard surface; they’ll need a repair.
But ‘shaking’?

I think if you attached them solidly to a rally car you might shake one to bits. But if you mean the normal movement of a lens in a camera bag being carried round the world, loaded into cars trains and planes, I’ve never heard of that damaging any camera gear.

And not long ago a Pentax lens was used on a satellite due to its performance.

Wonder why NASA don't use an American lens?

I believe there is still a Hasselblad still floating around they dropped on a space walk.
 
I watched a vid once about the making of Cooke video lenses and they did indeed drop one to show how robust they are. I wouldn't recommend that with a consumer grade lens.
 
Topcon cameras and lenses were allegedly very tough. The company held the contract to supply the U.S. navy with 35mm equipment from 1965 to 1977 and their adverts made much of the equipment's ability to survive in very rough conditions at sea and in combat.
