The Series E lenses are highly underrated. I have the 50mm f/1.8 and the 135mm f/2.8 and both of these are very good lenses. If they had the same standards for the other lenses in the series, then the 75-150 zoom should also be good.

I have the 35-70 f/3.5-4.8 AIS zoom, but have not used it yet. However, the one I have looks and feels like very cheap plastic: it came with the FM10. I don't know if there are other versions of this lens though.
