Alright! I was looking at that same converter.
But the sight didn't say if I could use it with
the 28-300, so I've held off. You can't use it with
so the EF-S "S" lenses (I don't think) and several
others from what I gathered. But I was thinking maybe
a Sigma 70-300 might work pretty good. Just not sure
about the zoom with a converter. But seems like someone
told me it did fine. You've got me thinking again, lol.
Thanks! Good shot like all the other macro stuff you're doing.
