I'm in two minds about this. I think I would love to have the capability to tune lenses if I want to, but on the other hand I'd rather like it to work perfectly as delivered from the manufacturer too.
For correcting the focus of a zoom lens, it sounds like to do a good job you would need to determine 16 correction values... testing at infinity might be fun... wonder if FoCal could help automate this in due course?
