Tips for Diopter Adjustment:

In bright conditions on the ground, the pupil of the human eye constricts making it easy to adjust
 diopter when the depth of field is deep while the adjusted viewfinder may not get the perfect focus and difficult to see the viewfinder image when the pupil opens in the darkness underwater while the depth of field becomes shallow especially with presbyopic eyes due to the focus function
deteriorated fire.
Although it varies between individuals or different ages, it takes about 15 minutes for the pupils to open to adjust to
dark when you plunge into darkness. Therefore, it is recommended to perform the diopter adjustment in a room
dark after 15 minutes when the pupils open as if they were under water, allowing a mass to be obtained
 perfect focus of the viewfinder image even under water
Since this method of diopter adjustment works quite well, we designed the Linear Viewfinder II for the X-2 without expensive diopter adjustment features.
