Without any tubes at all. That's one reason I like it so much. The other
is that it is really sharp down in that territory.

That is the normal 135.2.8, which may be ok in the center at that
extention, although I wouldn't use it seriously without testing, and
likely not so good at the edges.
The true macro 135/4.5 is a short mount lens designed to be used only
with the 65-116 or a bellows. Because of the short mount and short
helicoid, it only gets to 1:2 on the 65-116. This is quite intentional
on Oly's part. The macro lenses were designed for serious macro work and
each is optimized for a specific magnification range. For going from 1:2
to 2:1, they recommend the 80/4. The 135/4/5 is actually very good past
1:2, but it needs the bellows to get there.
