A 150mm lens is less than 3/4 as long as a 210mm lens. Figure it out
- a much bigger piece(s) of glass significantly further out for the
70-210.
No wonder it's a lot bigger, heavier, more expensive etc. Has nothing
to do with coverage.
I think that is part of it, but the other part is the 150mm zoom was made for
the smaller sensor. It wouldn't make sense to make it heavy or large. They set
out to make it as compact and light as possible.

Making it for the smaller sensor doesn't really allow making it
smaller. That's the whole point.
