Can you calibrate autofocus on a Canon 60D?

I’m seeing slightly different autofocus accuracy with different lenses on my Canon 60D. In good light and with a fast shutter speed, some lenses seem to front- or back-focus a little when I review images closely. My 50mm prime appears more accurate than my 70-200mm zoom, and manual focus often seems a bit sharper.
I’ve read that some Canon bodies offer autofocus microadjustment for individual lenses. Does the Canon 60D have any way to fine-tune autofocus accuracy myself, or would calibration require service?

You adjust focus on the camera - not the lens. The Canon 60D does not have a micro focus adjustment needed to do this.
You may try sending in your camera and lenses in for adjustment together, but it is not something you can adjust yourself on that body.
If your 70-200 is significantly slower in max aperture than your 50mm, then it likely doesn't autofocus as well because of the slower aperture. More light = better autofocus.

No. The Canon 60D does not offer AF microadjustment, so you can’t fine-tune autofocus per lens in-camera.
On bodies that support it, autofocus adjustment is done in the camera body, not on the lens. Since the 60D lacks that feature, your practical option is to send the camera and affected lenses in for service/calibration together if the focus error is significant.
Also, it’s normal for different lenses to focus a bit differently. A lens with a wider maximum aperture generally gives the AF system more light to work with, which can improve autofocus performance. That helps explain why a 50mm prime may seem more consistent than a slower telephoto zoom.
