Bad guess. I visited both sites, scanned both pages. I saw, on BOTH, a
lens diagram with a focal point, and what appeared to be an image that was
upside down from the source.
What subtle issue did I miss with these instrumentation cameras? How
macro-focusing desires all too easily lead to "bug's eye" lenses?
