John, I recently sold a gorgeous Pentax 67 outfit with 4 lenses etc when I discovered the joys of a $65 Minolta Autocord. It's as good a solution as I've found for TTL focus while the grandbabie action is unfolding. And it's light as a feather. I dream of an autofocus Fuji 645 but just haven't found one for 65 bucks yet.
