What sort of motors do the f/1.4 primes from Nikon use? Are they a modern design or an older one? If an older one, is anything known about the durability of that type of motor, given the wealth of data that must now be available for it?

As I understand it, Nikon has two types of AF-S motors, an older ring-type and a newer mini-type.  The only way to know which lens has which type is for someone to dismantle one.  The 24, 35,  and 85 f1.4 G's all have the newer mini-type so I assume the 58 does also.  I have heard anecdotally that part of the change to the newer motor was reliability, but I certainly don't have any statistics to back that up.
