On the S2 if the lens is back/front focusing you have to send camera and lens in? So just a flat high contrast target would be the logical choice.

The benefit of the Lens Align is that it has a flat front standard with high-contrast focus target and angled ruler in plane with the standard. While you can’t adjust AF like on Canon or Nikon, it does give you a a pretty definitive method of quantifying AF accuracy. We’ve actually used it on M cameras to see rangefinder accuracy.
