Haven't used any of these myself, but the 100-200/5 was tested in a swedish
photomagazine in the 80-s and was considered the best of all tested, it
outperformed the Nikons, Canon's etc. Summary was "This lens delivers
absolutely firstclass results". On a 1-5 scale it was something like 4.8.
Drawbacks were slow-speed and 2.4 meter close-focus.

No, the Zuiko supports close focus at 200mm only.

Haven't tried with any closeup lens, but at the close focus setting (0.85
meter at 200mm) I really beg to differ. I have made hundreds and hundreds of
close ups this way, some sold, some have won major photo contests,
absolutely beautiful performance. A true macro lens would of course be
sharper at the edges but this is uninteresting since this focal length is
used for a very shallow DOF. If prime sharpness all over is your goal, go
for a 50macro instead, 10 times easier. Well at least that 's how I would
do, your milage may differ.
