I've had the 75-150mm zoom for almost exactly 20 years now. My experience
with it is that sharpness is Ok, but it is prone to low contrast, especially
in back lit situations. That may be better in later versions than mine.
One thing to keep an eye on is it's tendency to become a varifocal lens
instead of a true zoom. That can happen suddenly; something gets out of
alignment and focus will drift when zooming. The image quality however
seems to stay fairly good. The last part is strictly subjective. I have not
made any systematic tests.

Lars
