Why do I love my new 24-70L?

not so fast ......the problem with this lens when used on a 1.6x body (mainly the older ones D30,60,10 to name a few) was that this lens is very demanding.
front and back focus issues exist and if the body and lens aren't in perfect sync, there will be the "soft copy" issues.

i tested 3 copies and one out of the three were bang on. all three were sharp, but with "MF". AF revealed a different story, so calibration has a lot to do with the results.
user error exists, but no modern day camera and lens should be harder to use than a typical P&S.

Nice shots,I share your love for this lens,I would never part with mine.

There is a group that were sent out that had bad quality. That is true. And I do know some people actually ran into problems.

But even on here, I have seen people complain about the lens when they first got it, but then get used to it and see that it was user error.

And there are a lot of "my 20D is soft posts."

This equipment generally has a higher learning curve. However, there are also problems out there. The 24-70 does have bad copies that need re-calibration, there are Sigma 30 1.4's that do need recalibration,

but the user error does exist and sometimes is fed by seeing bad posts..... It's just human nature....

I'm sorry you had problems.

Thanks for the comments everyone. Another good think I notice about this lens, is that autofocus is FAST! This lens in combination with my 580ex have made me happy, happy, happy.
