Hi--

(Catching up on e-mail...)

Hmmm, seemed like when I stopped cluttering up the photo NG with
my anti-auto-features tyrades, people soon forgot me, and the
e-mail deluge quickly subsided...;-) Thanks for the comments!
(After a couple of years of a-few-hours-a-day one-finger-blabbing
on the NG's [and a growing interest in video...], I took leave
of what seemed to be a {possibly...} bad habit...;].) (An', peeble
could take a rest from my nested run-on sentences...! ;-)

Haven't used the Tamron. The secret is TC's are a GREAT way to increase
magnification in macro, often with no optical downsides (assuming a stop
around f11-16 is practical) - the TC200/1 is also excellent for this,
and it even seems to cheat diffraction a bit... (see the bugs on my web
page). The most magnification comes with the TC closest the body (and the
14/14B won't fit the 2.8 macro lenses directly anyway...). Don't be afraid
to add an achromat to the front, also - it is often sharper than the tube,
and it sometimes works well combined with tubes and a TC (the Nikkor 200mm
f4 non-macro is very sharp in a TC with the Sigma achromat on the front at
3+X magnification around f11 1/2 [still with an auto diaphragm]).
