Yes—this is very likely a habit issue, and the main solution is practice.

If you’ve spent years using your left eye, switching to the right can feel awkward at first, especially with a different camera style. Needing to consciously align your eye and struggling to take in the whole finder are normal when changing a long-established shooting pattern.

It’s also worth re-testing eye dominance. A simple and reliable method is to frame a distant object in a small opening made with your hands at arm’s length, then slowly bring that opening back toward your face while keeping the object centered. It should naturally come back to your dominant eye.

If the result still says right-eye dominant, that suggests you may simply be more practiced with your left eye than naturally suited to it.

Helpful practice:

• Use the camera regularly with the other eye.
• Practice bringing the camera up to your face repeatedly.
• Try shooting with both eyes open, especially with a rangefinder-style finder.

So: re-check dominance, then expect improvement through repetition.
