The only adjustment on the Peak 1 is the viewfinder diopter adjustment. If it is not set correctly and you have presbyopia (inability to alter the focus of your eye), then your prints will be blurry.

The optical components are easy to disassemble and there is always the possibility that someone took it apart and buggered it up by not putting the focusing reticle in the correct location.
