I hadn't tried it yet, but I gathered from the picture documentation with my
T-8 that is was not recommended with the 20mm. Why not? My guess is there
is a blind spot near the upper magnification limit that renders the T-8
totally ineffective. But at lesser magnifications all would be well.
That's just a guess. Anyone know the whole reason???
