Technique aside, this is marvelous photograph, Jostein. Although you
seem to have affinity to (for?) this kind of macro photography at least
since 2006 when as I remember you were gearing up towards competing ;-)
with Mark Cassino on his snowflake photography.

There was some exchange on the list about macro photography and
extension a few days ago. Personally I prefer to use stacked lenses for
magnification beyond 1X. Here's one I took today, using the 645D, and a
150mm lens stacked with a reversed 75mm. The magnification of this combo
is 2X. That's about as much as I can cope with when working handheld.
The image is severely cropped, but the motif gives you an idea of the
possibilities in the field with this kind of setup.

One reason why I prefer stacking over other solutions is that exposure
automation keeps working. So you don't have to stop down the lens manually.
Another reason is that P-TTL keeps working. Well, sort of; you have to
diffuse the flash to avoid overexposure because of the short working
distance, but that's okay because you really don't want specular
highlights and sharp shadows anyway.
And if you're patient, you might actually make AF working. But you have
to keep the camera very steady. :-)
The knack is to find to lenses that go well together. According to John
Shaw (Book; "closeups in nature"), lenses in the normal range are best
for reversing, and moderate tele lenses best for attaching to the camera.
Personally I recommend using a tele lens with IF because it makes
working distance more predictable.
