Hello all,
I am just kinda jumping into this conversation, but was reading what Dan
wrote below and am wondering if there's an operational definition of what
"macro" truly is in this thread... True "macro" isn't measured by the
distance from subject to lens, but rather how large the object is produced
on the film or sensor in comparison to real life. So, if the lens maker
states that the macro is 1:4, it means that the object is 1/4 life sized on
the sensor. So, 1:1 is life-sized (where the object is as big on the sensor
as it is in real-life...)and is "true" macro. If the object is larger than
real-life ("super" macro, I suppose...), say 2:1, it becomes micro.
If you want a greater magnification, a good macro lens (such as Nikon's
105mm "Micro") will do a great job and allows true 1:1 imaging. Beyond this,
a good set of extension tubes will work nicely to give you even greater
magnification.
Hope this helps a bit and that all of you have a great day!

Subject: "Super" macro...Andy?
After posting this, and pondering the idea that macro just doesn't go
micro enough, I did some digging and found this product:

Now that I think about it, Andy, is there a rather portable, more
microscopic, attachment/lens you could possibly use in the field?

The subject insect is less than one inch long. And I can re-photograph a
color transparency, on a light-box, almost full size - which is a really
useful way of digitising my 35mm material - see my orchid photos, taken from
transparencies re-photographed on a light-box by the same camera -
