Tough choice, 135mm f/2 or 70-200 f/4 IS. What would you do?

Hi all,

Just wanted to point out that the original query is old, from 2011. I'm afraid I revived the thread above when I looked at Great Bustard's 100 f/2 photos (having been forwarded there by GB from my thread elsewhere on prime lens suggestions), and wrote "Great shots" (or similar).

Not that I'm not enjoying all this lens talk, only to say that the original questioner may not be reading all your advice anymore ...
