Question

What is a diopter in kodak cameras?

Answer 1

the diopter is a device on the camera viewfinder that adjusts the viewfinder to make up for glasses, contacts, etc. It is often difficult to look through a viewfinder with glasses on , so you adjust the diopter to be able to see the correct picture without glasses on.

Hope this helps!

Answer 2

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.

An adjustable diopter lens, part the viewfinder on many digital cameras, lets you focus the viewfinder to match to your eyesight, be it nearsightedness or farsightedness. The dial is located near the viewfinder.

By rotating a dial, k**b or slider, the image on the viewfinder will come in and out of focus. Make adjustments while looking through the viewfinder. Stop adjusting when the scene is sharpest. If your camera has focus brackets, keep your eye on them until they come into focus
