50d and 24-70L focus question

Hey guys, i just traded my 24-105L for a 24-70L and I was out shooting pics of the kids today for Easter and only caught maybe a couple of clear pics. The rest were out of focus and blurry. Has anyone else had this problem? I've heard great things about this lens and don't want to be disappointed by it. If i need to do something on my camera, i will. I shot my 70-200L f4 non-is and go crystal clear pics.
Thanks!

as always, impossible to help without comments

sometimes it's hard to nail the focus especially if it's a moving object. not sure how to help you though...except to keep testing it out to see if it's really a faulty lens or maybe you just needed some time to get used to it.

I will say this lens doesn't nail it as well as my 70-200mm on my 50D.

Not sure what it is, if it just that the DOF is smaller due to things you are taking pics of being closer? Not sure.

I was reading on some sites that you might have to microadjust the lens through the camera settings. I am going to try it today and see what happens with that. Might have to send it off to canon for calibration. Everyone that i know that has this lens says its fantastic.

I meant to say its impossible to help without pictures...my bad. Post some pictures and we can provide feedback

Like mentioned already... We need to see some pictures.

That being said, it took me a while to learn how to use my 24-70 when I first got it because the thing is so darn heavy. The 70-200 f4 seemed to balance well on my camera vs. the 24-70 which required more attention to my handholding technique. Also going from an f4 that I mostly shoot at 6.3 to a 2.8 required more thought concerning the depth of field I was suddenly working with.

Now I am having the same learning curve with the 85mm 1.8 because it is no where near as heavy as the 24-70 and the dof is even smaller than compared to the 24-70 2.8 or the 70-200 f4. Just takes some getting used to.

Please post some pictures and I am sure there are some great people here that can help you out....

Check my impression with same setup

My 24-70 has been bang-on on every camera I have owned.... except for the 50D. If I recall correctly I had to dial in a fair amount of microadjustment to get it right.
