Anyone annoyed that the Nikon D5100 camera will NOT autofocus with some Nikon lenses?

This is the kind of unconditional defense of Nikon that I was talking about earlier. I will add 'quiet operation' to the list of reasons posited by the Nikon apologists.

*Size

*Silent Operation

The reality is as follows; when you attach a quiet AFS lens to a camera with a focusing motor, the focus motor does not engage. There is no extra noise. None. AFS lenses operate just as quietly on all cameras whether they have the focus motor or not. AFS operation is not affected at all whether a camera has a focus motor or not. Users still get that quiet video operation with all AFS lenses.

However, once Nikon took away the focus motor from the entry level cameras (and mark my words....entry level is not the end) they have obsoleted all of the older style autofocus lenses on these cameras. They have greatly reduced the value of millions of legacy lenses that their loyal customer base has collected over the years. They did this, not to ensure quiet video operation, but to force the next generation to buy new versions of all of these lenses again. Nobody is arguing that AFS isn't superior to AF and AFD....it is. It's quieter, faster and probably more accurate. However, there was nothing stopping Nikon from supporting camera driven focus in all DSLRs other than sheer unadulterated greed. Remember, camera driven focus isn't an old and dead technology, it still accounts for about twenty percent of the lenses that Nikon sells brand new today (available lenses, not gross sales). And, as the OP discovered there are still some lenses that have no AFS equivalent such as the defocus control lenses he refers too. Nikon is screwing us all yet some of you are inclined to thank them.
