13. Preliminary Conclusions:
It appears that in order to do good macro photography, I am
going to need better lighting. With better light, I can get
better depth of ๏ฌeld which means sharper images.
As far as the lens setups are concerned, the 17-40mm lens
with the 36mm extension tube gives me large magni๏ฌcation
at a short working distance. The 70-200mm with 68mm of
stacked extension tubes provides increased working distance
at the loss of magni๏ฌcation.
Advice would be appreciated...
