Why not just try and tell me which of the four images I posted many pages ago are shot with which lens, surely that should be easy seeing as how the 135 has a "unique look"? And that is my point, yet again, it is not about comparisons, it is about the FACT that nobody can RELIABLY tell what image was shot with which lens, nobody who alludes to this "unique look" can reliably identify it, if you can't reliably identify it it isn't "unique".
I answered that already, several times. It is not hard to use a lens with a unique look in a way that nobody can tell the difference with a f/4 zoom. It has unique look when you use it in a unique way.
I have comparisons of the 24-105 with the 50L, the 85LII, the 35L. You would not be able to tell a difference, and even under 100% it will be hard to say which is which. I can post them if you insist. So what now, since nobody can tell the difference in those
shots, those three primes are useless?
