<<That's a great shot!  The only thing that you might complain about is the OOF 
back side antenna.  Colors are fine and the bands are clear and sharp.  I 
realize that you are more of a perfectionist than I, but I would call it a 
<<successful mission.

Thanks Jim. It was a 50 min drive and an hour hike for a low likelihood of even 
finding one.  I was astounded when it showed up.

 I was impressed how resolution was possible with a CU diopter built for a 
shorter FL lens.  The lens was stopped down and I tried to keep the B'fly 
central and have it placed where I wanted after a gentle crop, to 
optimize IQ with the diopter.  I had waay too much trouble with blur at least 
in part from AF issues.  Perhaps a different mode would have been better.  I 
wish Oly had a firmware patch allowing the IS to take into account a diopter, 
but that is clearly too much to hope for. I had to stay under the max SS and 
didn't dare go over 1/200 for a non system flash.  That might have been an 
issue as well given the magnification.  Minimum handholding speed should be a  
function of the FL of the diopter and the mag before accounting for effects of 
the IS system.   What I don't know if it is possible to  consistently hand hold 
that combo at 1/200 at about 1:2 to 1:1 (equiv) mag.  I took a few practice 
shots in the house and it seemed OK, but 4 test shots only get you so far.  
Then there is the unplanned for adrenergic effects of trying to photograph a 
never been seen before handsome critter.
