Really? in years past focusing groups flopping around inside lenses would cause outrage.
You should probably avoid examining any modern lens that has vibration reduction tech built into it too. Similar story, just not as noticeable as the little Sigmas (which don't even have vibration reduction as an excuse).

Too late, I already have a few IS/VR/OS lenses from Canon, Nikon And Pentax.

True. All the magnets and complex electronics in such cameras (and lenses) will probably be dead well before 30 years elapse. Everything will be bricked.

The most disturbing 'rattle' I've come across is that of the Sigma E-mount 19/30/60mm f2.8 lens trio. When any of those lenses donít have power, the focus group flops around inside the lens. Lens sounds like a maraca.
True. I have the 19mm, and experience exactly what you describe.

I get that noise/sound also. Like a small motor turning. Not very loud. Tried several types of lenses and always there.
