Interestingly, both of these go to 1:1. (whatever that means in 4/3
terms [1]). I can't imagine trying to _use_ a 300mm equivalent lens at
1:1, though -- it's tricky enough framing things with a 50mm, so a 300mm
would just be ridiculous, not to mention getting any sort of focus
and/or image shake issues.
A tripod would solve the latter two, but you'd really need a geared
head to frame things properly, as far as I can see. Maybe I'm just being
pessimistic, and having a lens that'll focus closer is always nice if
it's available, of course.
