Dioptic Adjustment

[ChrisN]

I have some questions about the Dioptic adjustment.

How do I set it up?

Can someone walk me through the steps to doing this?
Do I need an optician or something?

Do I need to focus the lens on something and then set it up that way?
Do I need to have the focus point set a certain way to get an accurate focus before adjustment?

Help, please help me.

Focus on something that is easy to see through the viewfinder, yet distinct. Roll the diopter adjust ment one way - tar far - and step back one click at a time until it looks right. Note the setting.

Look away for a moment to let your eye relax. Now roll it the other way - too far - and adjust back. Note the setting.

If both settings are the same then you're probably good to go. But you may need to do this 2 or 3 times, and pick 2 or 3 different subjects. If you don't pick the same thing twice after three tries then pick one or the other, or the one in the middle.

Don't tryy too hard, and let you eye relax in between.

For a focus target, get a newspaper front page with large headlines and also fine text. Tape it up on a wall. Stick your camera on a tripod and place it across the well-lit room. Then try the procedure that Scottes mentioned.

Once I got mine set, I placed a microscopic amount of white-out on the dial so that I can reset it to my setting even if somebody else has changed it.

I adjust it so the focus point outlines on the focussing screen are crisp. It seems to me that since they're on the screen, and that's what you want the diopter adjustment to let you see, it's the best way to go. Finding a good outside target isn't always as easy, either.

An old thread, but i've a question about my camera...

I've follwed the instructions stated here [thanks guys] and everything's good other than the fact that the settings in the lower part of the screen telling me the aperture etc are now "out of focus" ... does this mean my camera needs looking at?

First off what camera you using?

[KennyG]

The 'right' way is to set focus for what you see in the viewfinder without a lens - the information display and focus points, not what you see through an attached lens. This is the only way you can be certain of being on focus with a lens in MF.

Do you have bifocals? If so, you can only correct for either short sight or long sight, but not both.

Ian - 300D

Kenny - Ta, tried that, and there seems to be a range of settings that the focusing points are sharp, so i chose the center one... the dial is almost at the bottom of the range.

Marc - Nope no glasses here.

Thanks for the input.
