Number 3 was the best, I kept that for a while, before I let that one go as well.
Incidentally it was the one with the full metal focus ring, which I also like most from appearance point of view (not that it would really matter).
The yellow tint was present with all of them, though. Could be removed with WB settings but as I said, it was more the case with the Rokkors than with all other lenses I owned.
I don't expect a difference now, but I try to be open minded.
