I agree with Tom. Among my growing collection of prime lenses [Hi, my name
is John and I'm a Zuikoholic] all but one are MC, but they date from
various periods. The one SC I still have is an absolutely great lens.
This is because it's in pristine condition, and doesn't have much to do
with SC versus MC.
The only time I worry about when the lens was made, and use the markings
(and serial number) to differentiate, is when the lens was reformulated
internally. This occurred with a number of the lenses that have been (or
were) in production for a long time. It is then that I look for one of the
specific formulations based on the lens markings.
I had a 75-150/4 "S Zuiko" (meaning it is an "economy" class lens) for over
20 years. It was equal in build quality to all the other Zuiko's and was a
fine lens for me. I used it with a third party "cheap" 2X teleconverter
too, and the results weren't too bad (but not the same as using the 300/4.5
prime). It is light weight and can be easily used as a very decent,
inexpensive portrait lens. Among several important things about finding a
good 75-150/4 is making sure the focus does not shift when rotating the
zoom ring. To test this, zoom out to 150mm, critically focus on something
you can easily focus on about 20-30 feet away, then zoom back to 75mm and
see if the focus shifted much. A very, very slight amount is OK, but it
shouldn't be much!
Don't do the test starting at 75mm and zooming out to 150mm; this advice
applies to doing the test on any two-touch zoom. You can't focus as
critically at the short end as you can at the long end on any zoom. Your
likelihood of seeing a focus shift is pretty high as a result . . . but not
necessarily because the lens is shifting focus. That's why you start at
the long end first.
Sold mine earlier this year because I just wasn't using it. It was
redundant with the 35-105/3.5-4.5 and several primes, and since I'm
primarily a user of primes, the 75-150/4 went on the auction block. That
is was an SC and an "S Zuiko" economy lens never concerned me!
