Though your butterflies are pretty I don't have
that much patience. All my macro photography
will be pretty stationry (PCBs, gears, scratches)

I used to get around the DOF problem with
my old pentax film camera by just shutting
down to F22 and leaving it on a tripod for a
while.

I found the digital cameras (like my old
CP5700) with their tiny sensors used to get
good DOF regardless of apature. I am hoping
the small sensor in the D70 might help a bit
as well.
