1- Respect the S-M-C, none, it's better (to me)
2- Respect the S.T.,
a) The 8 el. has less or not yellowish cast at all. It's very important. As you know, the yellowish cast and the virtual necesity of put the lens under UV light (or similar) time to time, is one of the few cons of the S.T. 7 elements lens.
And if you don't do this, the image can lose the IQ natural of the takumars lenses.
b) The 8 el. has more resolution power (only a bit, but there is).
c) The 8 el. has better bokeh.
c) Marginally, the 8 el. is less common than the 7 ones, and that improves the interest over it and increases the resale value.
The S-M-C (and SMC too) is over all the S.T., 8 or 7 el.
And my choice among the S.T.s is the 8 el. because all that I said before.
Regards.
