Porro binoculars with Sports-Auto-Focus (see also key):
Adjust both dioptre settings to “0” and everything from approx. 20m and beyond is always sharp
and clear. If this is not the case, one or both eyes may be ametropic. This has to be adjusted.
1. Choose a very detailed and remote object (approx. 200m distant).
2. Cover the left objective with your hand or the objective protection cover and look through
the binoculars.
3. Now turn the dioptre setting on the right ocular until you can see an entirely sharp and clear
image with your right eye.
4. Please repeat the same steps for the left eye. Now everything from 20m and beyond is
always sharp and clear.
