The flare on the second image may be unavoidable, I have similar
problem with my 35-70/3.6 although it is MC version. The 75-150 is a
SC lens with 15 elements, hard to eliminate the flare and ghost image
in such situation where strong light sources are included in the
picture.

Although with these two small pictures others cannot see how good it
was, but I would say if you can find this lens with very clear
glasses, you should get it. The price of this lens is usually cheap
(~100-120 for a 9+ in ebay) but the performance is really nice.
I had an old 75-150 with scratched glass inside, which also had a bad
filter on it, the picture was never came out right so I had not used
it for years. Last year I had a look on it and found the old Olympus
1A filter was very yellowish in color, it even had 0.3 stop light
loss. I removed the filter and took the lens out for some shots, the
slides came out with great color and the resolution was also fine. I
immediately go out to search all local used camera shops and got a
like new one. If you like the traditional color of Zuiko, this is
the right one.
