Abstract:
An instrument accommodation compensation is built into the viewfinders of single lens reflex cameras. The extra accommodation required when using these cameras can cause difficulty for some patients. This paper presents a simple method for measuring the instrument accommodation compensation of reflex cameras and presents the results of such measurements for several cameras.
