What is a diopter in kodak cameras?
Diopter (d): A term used to identify the refractive (light bending) capacity of a lens. In magnifiers, there is a direct correlation between focal length and diopter. To find the diopter of a magnification lens, follow these steps. With the eyes 10″ above the lens, move the object to be viewed to the point the greatest distance below the lens where it remains in sharp focus. Measure this distance and divide into 1 meter (39.37″). The result is the diopter of the lens – e.g., if the object is at a 13″ distance then it is a 3-diopter lens (39.37/13 = 3d). Each diopter increases the size of the viewed object by 1/4 (25%) when the object is at its full focal length from the lens. If you are wearing eyeglasses still want to shoot photos without them then a digital camera with an adjustable diopter lens is the best option for you as slight adjustments can improve clarity and sharpness when looking through the viewfinder.
