I've been looking for one of the Cokin Creative Ring
Flashes! The first time I looked on ebay, they were
going for over $100 and I declined to bid on it. Now
that I have gotten over the sticker shock, I haven't
seen one since. A manual macro flash would be fine
with the R8/9 since they have manual TTL flash
metering. I figured that I would sit down with a grey
card, meter each distance with the 100 and 60 macros,
and make a quick reference card for the back of the
flash, although that would vary with how you are using
the heads. According to one book I read, (Schaefer?),
if you attach a manual flash to the front of your
macro lens (he screwed a hotshoe onto a metal lens
hood), once you determine the f-stop for your
film/lens combination, the light loss from extension
of the lens (bellows or tube) offsets the brightness
increase from being closer, so the expoure doesn't
change. I presume that would not hold for the 100 APO
since it is one of those fancy part-zoom lens designs
where the focal length shortens as you focus closer.
IIRC, the 100 APO is more like 70mm at closest
focusing distance, so at closest distance it doesn't
actually have that much more working distance than the
60mm! If you don't believe, and have both lenses, try
comparing them!
IIRC, back in the day, Leica recommended the 2x with
50mm Summicron and longer, although it was
particularly optimised for the 135mm Elmarit and the
180mm APO. They may have not recommended it with old
zoom.
I'm starting to ramble like Rabiner. Must be the Mad
Cow.
