Third Party Manufacturers / Re: Is it time to consider Sigma lenses seriously?? competitive to Canon?« on: September 09, 2013, 07:02:41 PM »
The Sigma 35mm 1.4 for example is light years ahead of Canon's offering. It's like night and day. The 85mm 1.4 is also light years ahead of Canon's offerings
"Light years" and "night and day?" To me, light years is something like the difference between iPhone shooting in pitch darkness vs. full frame. While I am very happy that Sigma (and Tamron) are coming up with competitive lenses, which hopefully drives Canon to more R&D and to lower their crazy prices, my concern about how these lenses will behave with FUTURE Canon bodies remains.
For example, I did have the Sigma 70 Macro, which was one sharp lens, but it would not autofocus properly in live view with my new-then Canon body, and Sigma service could not fix it, either.
