If you want an affordable test, get a used Tamron 28-75/2.8 ... that will
pretty much tell you if the shorter focal length in combination with one stop
more does any good to you. (if that is not the case, sell the lens without too much
loss).
Personally I find 70mm is a bit short for portraits... but ymmv.
