Your La Sardina camera comes with just two simple focusing settings (0.6-1m and 1m-infinity) which is located on the lens ring and you should remember to alter this depending on how close or far away your subject is.
0.6-1m – If whatever you’re taking a picture of is between 0.6m and 1m (i.e. close-up) then just be sure that the camera is set to this setting. Just make sure the lens ring is turned to the right position (from the front of the camera.)
1m-Infinity – If your Lomographic subject is at least 1m or further away, then turn the lens ring to the left to make use of this focusing setting.
