No one mentioned the Pentax SMC F 1.7x AF Adapter. Makes the MF lens a very fast auto focus lens!
1) Finding one (hens teeth?)
2) Being able to afford one!
3) The reduction in effective aperture - as I said above, anything more than a 1-stop reduction will cause problems with a lot of lenses.
2 Yes expensive
3 Works fine with most prime lenses.

Theoretically you could use one of the older Pentax (K, M or A) wide angle lenses, line up all the orange numbers (aperture set to f8, focus varies between lenses but it's usually the first numbers down from infinity) and have everything in focus from infinity to a couple of metres using this hyperfocal setting, although I've yet to borrow a video-capable DSLR and try this.

Will be a shame if we don't get some rain tonight! A sunny day today with the main effect being some reasonable summer surf.
