Marc,
The lens you have 50-135 AIS is considered every bit as much of a
classic as the 75-150 Series E. It is also multicoated while I am not
sure the series E may be only single coated. Your current lens is
constructed and assembled in the classic way of the best Nikkors of the
past while there may have been a few short cuts (like glue) used in the
75-150. The 75-150 definitely has an excellent reputation for sharpness
and is a cult classic. The loose zoom is common on the 75-150's that
I've examined. The 75-150 in excellent condition is often found for
about $200 USD. The 50-135 in excellent condition is more likely found
for about $350-$375 USD. There is not a huge difference in 135 vs 150 on
the long end. If your intention is to have a longer zoom range I would
look for an 80-200 f4.5 or f4 although they are larger and slower or
keep the 50-135 and get an 180 2.8 EDIF or 200 f4 AIS. John Shaw, nature
photographer, has done some excellent landscape work with a 50-135 AIS.
I admit I am biased toward the 50-135 AIS and you may have some very
good reasons for changing for the 70-150. Good luck.

Hello everyone!
A couple of digests ago I read this:
....... Just last weekend I purchased a 75-150/3.5 Series E at a
camera show (one that's been mechanically reworked to solve the loose
zoom
problem so common with these lenses)...............
I have come across one of these lenses, and having read that it is very
sharp, I am considering of trading it for my current 50-135/3.5 AI-S,
but I
am worried about this "loose zoom problem".... can someone explain what
is
that all about?
I would appreciate also any opinions on whether I shoud trade my zoom
or
not.....
