It's pretty brutal though. I guess you could mute it or something :/ http://www.youtube.com/watch?v=qM-SLrbti14 I loved it

Anyone else have this issue? Thanks!

alander98 Hatchling 1 post Joined Apr 2012 More info | Hi everyone. Perhaps a dumb question... Would the focus micro-adjustment feature available in 7D be able to compensatye for any front/back focus issues with a Sigma lens? And if so, would 7D actually register the settings selected for a third party lens (i.e. non-Canon). I've never actually done any micro-adjustments, but am curious whether this would work in case the 30 f/1.4 has some issues... Or would it be easier, or more recommended to send it over to Sigma for service? Thank you for any input.

They said they can calibrate the lens by itself, but if you can afford to let go of your camera for a week, it's best sending the body along as well since calibration could be slightly different from body to body.

Yes, the MA function on your 7D should be able to compensate for front- or back-focusing issues - assuming it doesn't need correction beyond the limits of your MA. I've read a few posts here where even +20 or -20 wasn't enough, so they either sent it in or returned it. 50D - Canon 60mm Macro - Sigma 30mm - Canon 70-300mm DO IS - Canon 17-85mm IS - Canon 50mm 1.8 II
