Is there a reason they can't make this lens autofocus? It seems like such a fine lens optically and so inexpensive. I would gladly pay 2x the current price for an AF lens. I can deal with the manual focus, but would really like an automatic aperture (to be able to easily and rapidly shoot at those f-stops where it is too dark to manually focus). That seems like it would be a lot easier to implement than autofocus.
on canon it would require electronics and a small motor. on lever driven camera bodies (nikon, sony, pentax) it can be easily implemented mechanically and has (at least in the nikon version of this lens, probably the others as well).
