Pretty much the same parts as in the small camera, and if you want to see the teardown of one look up Dexterslab2013 here, he has done a nice Sony ENG camera body recently which shows all the parts inside, along with the optical parts as well.
The internal lens assemblies are good though to inspect a PCB, nice good quality glass used there. I got them out of an old studio camera that I got on auction for $5. I got around $10 back just on the scrap aluminium in the case and the optical block as well.
