As for the AF feature, it sounds useful and very unusual.  I've never 
heard of any lens with a complete built-in autofocus system that works 
with almost any manual camera it can be mounted on.  Has anyone heard of 
another lens with a similar set-up?

I have a Sigma 70-210 lens with the same feature.  TBH it's mostly a 
gimmick - the AF is slow and not incredibly accurate, and requires an 
extra partially-silvered mirror in the light path that reduces the 
amount of light transmitted through the lens.  The lens is longer and 
heavier than it needs to be, and the manual focus is apalling.  The 
quality is OK though.  It's a fun idea, but I wouldn't spend more than 
the £15 I paid for such a lens.
