The plastic lenses are cheap crap for people who are willing to throw something away instead of having it serviced - they could have been made of metal, and still work in AF mode, but that would have been expensive.


My own experience is that in situations where you could really benefit from autofocus (i.e. very fast moving subjects), it's liable to let you down anyway with imprecise focus. I've now gone back to manually focussing everything....it's how we always used to do it!....with better results.

I get the feeling AF systems rely on you shooting at f5.6-f8 where most things are going to be infocus anyway. Once you really test the system with fully open aperture settings, the lack of AF precision begins to show.
