The technique that has worked well for me with an LS-8000 is to perform a forced autofocus just before the actual scan selecting a high contrast area as near the film center as possible. Default behavior is to autofocus the center of the frame before the preview, and not again. Since focus is so critical with this scanner there's two potential problems here: one, focus may drift or film may shift due to heating (?) if significant time elapses between preview and final scan, and two, the default focus point may or may not be on a high contrast area. The problem is limited DOF, and remounting using Gepe glass or Quickpoint glassless mounts may be helpful too. Quickpoint mounts use adhesive strips to hold film edges and stretch flat (available from www.reel3d.com). Or one could have a slide mount size piece of anodized black aluminum with an oversized cutout made by a machine shop, and the unmounted slide taped into place.
