Mike,
I own the Tamron 90mm f2.5 55mm filter lens..I can highly
recommend it. I would suggest you forget about the idea of the 1:1 extender!
This is just an extension tube WITHOUT any form of lens included. The major
disadvantage of this extender is that you have to remove the adaptall mount
from the lens, add the extender, replace the mount, and then attach the lens
to the camera!!! Assuming that an exact1:1 reproduction is not required it
is far simpler to leave the mount attached to the lens and use an Olympus
25mm auto extension tube. I hope this helps.
