I would like another tele lens to go as wide as possible (not fish-eye) while staying as fast as possible.
"a tele lens to go as wide as possible ... as fast as possible"??? What you want is going to be expensive or simply not possible. If you want to combine a wide angle of view with a tele, you need one of the "super-zooms", like a 18-200 or even the 18-250. But those are slow, very slow indeed, exactly where you would need a fast aperture most, at the long end.
Or you need to split the range into at least two lenses, a "standard" zoom lens, like one of those mentioned in the thread and a tele zoom. Both of course of the fast variety, which is going to be expensive (Pentax 50-135/2.8 or Sigma/Tamron 80-200/2.8 and the like).
A fast, all-encompassing zoom lens does not exist. Even if it would, the quality would be low or the price excessive, because combining everything into one package is very demanding.
