Snopchenko, I never claimed you couldn't get great shots with other lenses. What I said was that nothing beats L grade glass. If what you're using works for you and you're happy, that's great.
I am using a Sigma lens alongside L and non-L EF lenses, and it's never a question of settling for something. Even if had been building a kit from scratch with unlimited resources, there would've been a few non-OEM lenses in it (like a Sigma 120-300 OS, or the 85/1.4).
As for your Reuters friend, don't forget that they're looking for content not quality for media events.
Nope, not an excuse. Wherever I've been working over the years (paper, agency, website), the workflow went like: "First off, if the picture isn't sharp, it goes to Recycled Bin." I can't imagine Reuters being much different unless working with very extreme events - but in this case even the big agencies settle for TV screen grabs and cellphones (Mavi Marmara or Syrian civil war anyone...), so it's not a good point in itself.
How about you guys try to find a comparison for fast primes like the 85L f1.2 v2 or the 50L f1.2... oh that's right... they don't make anything that fast!
They have 1.4s of comparable IQ. 1/2 stop slower at 1/3 the price seems like a deal to me, especially since the Ls have their own known issues. No experience with any of those (L or Sigma), anyways, but I'd love to use the 85/1.4.
