I can't think of too many earlier zooms with macro ability at the long
end.
The Z. 50-250 is one of them though I can''t say I use it much for macro
given its bokeh, though should retry it. I think it is better than
given credit for if the vibration is dampened. It almost always make
the cut for travel.

As mentioned before the Viv S1 90-180mm macro is kinda huge but very
special going to 1:2 at the long end. I am not aware of any other
dedicated macro zoom like that. There is the Canyon 180 macro of
course and a newly designed OS Sigi 180 macro that is yet to ship. I am
eyeing that one for critters.
Moose's solution is waaay too convenient and defeats the very enjoyable
macro gear fussing routine and thus I rejected that option out of hand.
Never met a macro lens I didn't like for something,

"OTH, there is nothing from that era that can touch the Tamron 28-300 @
300 mm
for nature macros.
"Only" goes to 1:3, but that's at the long end, so the reach/stand off
distance
is great. On a high pixel count digicam,
cropping a isn't a problem. Assuming one magnifies the frame to the
same
display size, on a 1.6x sensor, it's the eq. of
1:1.87, slightly better than the 1:2 of many macro lenses.
Very sharp in the center @ 300 mm, closest focus. None of the many,
many such
shots I've taken has suffered from corner
issues, because of the nature of the subjects. I assume it's got
softness
and/or field curvature there, but I've never
seen them."
