It can be frustrating when you’re working in a Creative Zone mode on your Canon EOS 60D camera, and you accidentally nudge the Quick Control dial and make a change to a random shutter speed or aperture. That’s the bad news. The good news is that you can lock the dial in place when you’re in a Creative Zone mode. To lock the Quick Control dial, follow these simple steps:
Set the Mode Dial to a Creative Zone mode.
This won’t work in any modes in the Basic Zone.
Press Menu and navigate to Setup Menu 2.
Scroll to Lock and then press Set.
Choose Enable and then press Set.
Press Menu to exit the menu.
Now when you’re in a Creative Zone mode and you press Q to look at the Quick Control Settings screen, you can’t change any settings with the Quick Control dial until you press Q a second time and enter edit mode.
Press Unlock to temporarily unlock the Quick Control dial and make changes. Depending on the mode you’re in, rotating the dial (remember, this is before you press Q the second time) changes a different setting. In Av mode, it changes the exposure compensation.
