Using the diopter

I have totally confused myself and now need some advice, I wear glasses.

Should I leave the diopter in the middle or move it to suit when wearing glasses or when not wearing.

This of course when I use manual foscus, I have noticed that some of my photos are out of focus.

I would prefer to wear glasses rather than keep taking them off each time.

I wear glasses all the time, and set the diopter to show sharp grid lines in the viewfinder.

You should leave it in the middle when wearing your glasses.

Glasses on, diopter at zero, glasses off diopter according to your eye sight (I set to -3 as I am short sighted). I prefer to have my glasses off. As I am short sighted I cannot wear my glasses to look at close objects (ie the camera)

I've also found that, when incorrectly set, best focus is still correct focus only it's a lot harder to determine the best focus position.

Cheers

I think everyone agrees. diopter adjustment should be set with glasses on (or contacts in).

I have a -3.5 perscription, and have a lot of trouble (obviously) with distance. I simply can't be bothered switching glasses on/off to look in the view finder, and can't see well enough with out my glasses on to see a small bird at 50 feet.

Mine is adjusted to when I am wearing glasses (worse than 20-400 vision). If you are one of the lucky ones who sometimes wears glasses then adjust each time you switch from naked eye to glasses.

I only need glasses for reading, so this does not apply to me. I'm confused by those who say with eyeglasses on you set the diopter to center. I would think glasses or not, you adjust the diopter so the status display at the bottom is in focus (or the grid lines as Duck Dodgers wrote). Is the assumption that glasses always correct your eyes perfectly so center the adjustment?

I'm also curious about those who say they have the diopter set to a value. I don't think my K1x0Ds have any indication, I just know I'm "one click left of center." Perhaps the K10D has a indicator?

I set mine all the way to the right. I still need 1 more click though.

I don't think glasses will give you 20-20 vision in both eyes independently (more of an average of both eyes together).

Actually they should - unless you have a specific situation with your eyes (too much loss) or you're using off-the-shelf reading glasses.

I just joined the world of "Oh, 40? yup you need reading glasses..." and in my case, I set it to zero when wearing glasses, 3 clicks from the end when not wearing glasses, which means I then have a hard time looking at the preview on the back of the camera (and do the arms-length chimp-reach). So I wear my glasses now and just take them off as needed.

I have two favourite settings on my diopter, but I'm darned if I count clicks to get there. I wear glasses or contacts, and the setting is slightly different on each. My glasses are progressive lenses (they transition gradually from distance to reading) and probably I am a bit into the reading section looking through the viewfinder. I set it by pointing the camera at a clear sky or a white wall and setting for the clearest lines in the viewfinder.

You might find it easier to adjust if you take off the eyecup while adjusting. I know I do.

I have 2 sets of glasses - one for distance and one for reading. I tend to have the readers on when using the camera so I see the camera setting etc. I wear no glasses when actually taking the photo and have the diopler set accordingly - no great issues but it did take a bit of organising at first.

cheers

As LeoTaylor said, adjust the diopter until the grid/status display is sharp when you look through the viewfinder. There is no special setting for using glasses, adjust if needed.

I have to wear my glasses to look trough the viewfinder because the diopter
adjustment does not go far enough for my eyes. I just wish the information
in the bottom of the view finder would be easier to see with glasses.

OK - I'm about to thread-jack..

I don't wear glasses at all bu t I need to slide the diopter all the way to the right to get sharp lines. Is this normal?

And I have suspected that when I use AF, I get nice and sharp images but sometimes when I MF I get not so sharp images.

Maybe my eyes are screwy and I need glasses?
