The workaround for this situation is pretty simple - you'll have to learn some basic photography concepts, the critical things to learn are; DOF or Depth of Field <-- This is really important in conjunction with Aperture and Shutter Speed which form a trio you could say and form the basis of photography. In your case more so as it will help determine end focusing and sharpness.
Just remember that if you set the ring at aperture f/8, with the focusing ring lined up at the centreline you'll be able to focus and everything past 3 or so feet. Also depends on your sensor (itill have marks at the focus ring itself which will say distance, and on another area it'll have all variables of aperture range pairs so a f/8 could be left of the centreline and another f/8 to the right. If you match the distance ring, you can probably note that the distance starts small at one side and grows to a infinity symbol,
