Driving to the trailhead with style: Infrared view of Jekyll on Bug.

Just interested in knowing what others think about this -- I feel I'm

getting better at tweaking the focus after focusing in the visible,

but it's still hit-and-miss. What's the trick? This lens doesn't

have an IR mark, but our others do -- but even so it doesn't seem to

help all the time!

Is 750nm close enough to visible that I shouldn't bother reducing the

focus distance a little? It's Konica 750IR with the #25 on Canon

equipment.
