Canon PowerShot G12 Adjust the Viewfinder Diopter

Adjust the focus of the viewfinder.

If you use the viewfinder on your G12, everything may not appear in crisp focus. To remedy this, use the Diopter Adjustment Dial, located to the left of the viewfinder, to adjust for your vision (Figure 1.3). There is no “correct” setting for this adjustment so you will have to dial it in yourself. Simply look through the viewfinder (if you normally wear glasses, leave them on) and adjust the dial until everything looks sharp. It’s a small thing, but it can make a big difference when you use the viewfinder.
