How does one know for sure that the viewfinder is set at the correct diopter setting?

does what you see look sharp and clear? If so, it is set correctly

I notice you wear glasses in your photo. Make sure you set the viewfinder with your glasses on for distance.

Set your camera on a tripod and carefully autofocus on an object with high contrast. THEN look at it through the viewfinder and adjust the diopter until it looks the sharpest to you. Then lock down the diopter wheel so you don't accidentally turn it out of focus, and you're all set.

You're looking to get the viewfinder in focus with the diopter so make sure you have grid lines, focus points, etc. showing and then change the diopter setting so that these lines are sharp. The actual image can be blurry when you are doing this. What you are trying to accomplish when taking a photo in manual focus is to get the actual image in proper focus and to do that you need to make sure that when you look in the viewfinder, the "screen" the image is focusing on is in focus for you also. That's some bad language but most manuals cover this.

What you also want to do is look at your camera specs and see if the diopter range is narrower than your prescription if you plan "not" to wear your glasses. If it is narrower, than you might have to get a diopter add on to be able to get the viewfinder in focus without glasses.

Hi MT,

Using that diopter selection method, if you have back/front autofocus issues with a lens that you have not corrected, would that affect manual focus? I'm trying to run that through my head but I can't get it right :?:

If you have focus issues you will not be able to get the diopter to focus the viewfinder, but it will still LOOK sharp because its such a small rendering of the image that the focus issues would have to be TERRIBLE to look bad in the viewfinder.

Remember, unless you are manually focusing, the diopter setting is only important to your comfort. If you are manually focusing, you want the diopter setting to be as accurate as possible.

Are you talking about a special feature, or do you have a suggestion as to ho to do so on most cameras that use standard adjustment wheels; I have a Panasonic G3 and a Canon SX1S. My master (right) eye has vitreous detachment, and until I have surgery or learn to use my left eye, the sight in that eye varies almost daily making frequent changes necessary. I would like to set it at a reasonably common setting and lock it there. If I have a vision shift, i will have to use my LCD to focus. Thank you.

Take the lens off your camera body. Then, point your camera at your computer screen or TV screen with as white a screen as is possible on either the monitor or TV screen. Or aim at a portion of bright clear sky.

Then, adjust your cameras viewfinder dioptor until the "cross hair" focus point or the 'focus' "marks" on your viewfinder screen become focused at their maximum sharpness. You are NOT focusing on any image in the view finder, you are setting the dioptor to focus on the view finders screen. If the "focus" marks / indicators on the view finder screen are in maximum focus, then the image that view finder presents to your eye will be in maximum focus.......... Curt H.

DETACH LENS, (so you are adjusting focus on focus point, not image) - adjust dioptre (next to viewfinder) so focus points are sharply in focus. (easier against a white, or light background) Re-attach lens.

If you are Nikon user, and finds it difficult to manual focus in the viewfinder, I suggest using the 2x eyepiece magnifier

The only thing that has to be in focus with the diopter adjustment is the writing inside the viewfinder. Actually, you might find it easier to adjust it with the lens cap on. Turn on the camera, make sure you have some writing in there, and get a sharp focus.

Take the lens off, then you can concentrate on getting the viewfinder icons sharp, without getting confused by the image a lens would give-that is the proper way,
