Diopter Adjustment

So I think I have a problem with hitting manual focus these days because my right eye is going out of focus now. I've always had 20/20, and still technically do, but there is a slight issue with my right eye. I forget what the eye doc called it now, I have my report buried in my files somewhere.

So I need to learn how to use the diopter adjustment I think in order to correct for my vision anomaly. What's the best way to go about doing that? Do people have a preferred method for adjusting? Because how do I know when the camera is in focus if my eye isn't? I know there is that little knob next to the viewfinder specifically for this, but need to learn how to use it effectively.

All I do is look through the viewfinder at a distant sign far enough away to make reading it challenging, hit the AF button, then adjust the diopter until it looks as clear as possible in the viewfinder. No real science to it.

Cool, I thought that might be all there is to it, but wasn't sure. Thanks for the reply. Prefect vision for 36 years, and now it's starting to go. I don't want glasses man, but I don't think I could touch my eyes to put in contacts.

Even better would be to remove the camera's lens completely, or at least defocus it completely, and then use the little wheel to adjust the image of the focus screen so that the little box around the focus points are as sharp as possible.

What you need when looking into the VF is to see the image of the fous screen clearly. So actually focusing on something that is etched on that screen will give best redults.

If the AF were to be a little out, and you were using the image projected by the lens as your diopter focus tsrget, either you will not get a good point of focus at all, or you could just possibly get the diopter control to fix the slight degree of misfocus.

So you should always use the focus screen itself.
