A few (dumb?) questions about Diopter settings...

1. Is it weird that I have different diopter settings for different cameras, even if all of them are Nikons ranging from 2006 to 2015? (D40x, D5100, D3200, D5500, D7000).

2. Is it weird that I cannot seem to find a sweet spot? I fiddle around with the diopter (which is awfully placed by the way, absolutely impossible to adjsust it with my eye pressed against the viewfinder proper), and IIRC most of them are set somewhere in the middle rather than at any of the extremes, but the problem is...lets say I start out at one extreme just to make it really apparent what it looks like when blurry, then I adjust until I think the letterings and focus point indicators look sharp (as well as the actual vf image, if focused properly of course), but then a few seconds later I second guess myself and go a few clicks further...suddenly that looks (or feels, more like) sharp..then a few seconds pass and I try again and go back a few clicks and suddenly that feels better again...aso ad naseum.

Thing is I see so many comments saying to just (or that they just) adjust it until things look sharp, making it sound like it is the easiest thing in the world.

Could I have some sort of cognitive problem (or just quirk) that either makes me unable to fully grasp what "perfect" sharpness looks like, or that I always end up in a sort of "the grass is greener on the other side" sort of situation, or is this something a lot of people can relate to? (In which case I guess what the people saying "just adjust it until it looks sharp" actually mean is "just adjust it until it looks good enough"?)

I dont think I have ever had a situation appear where a photo I shot was blatantly out-of-focus for any other reason than user error, so I dont think not finding the exact perfect spot is hampering my photography (Though I did notice when fiddling around with my D7000 this evening that when looking at text on my screen through the viewfinder at like around 30-40cm distance everything looks tack sharp, but just leaning back (and refocusing of course) makes the clarity of the text feel significantly impaired, even though I can still read it just fine...just feels like I suddenly get an extremely minor case of dyslexia, if that makes sense?)

...actually, now that I try the same distance with just my eyes the effect is similar, so maybe there is something with my eyes actually? Which would not explain why I cannot seem to find the perfect diopter setting / that my perceived perfect settings seemingly changes for no reason even when the distance and everything stays the same, but I think it could imply that this perceived change in clarity depending on viewing distance (even small ones) is something actually unrelated to the issue of not being able to find a diopter sweet spot.

Hope my wall of text is somewhat readable, to be honest Im looking for peace of mind more than anything, so I wondered if what Ive explained is something a lot of people go through or if Im the weird one out?

Greetings. I have a bit of OCD so I feel your pain. With a new camera I place a book of text at a reasonable distance, adjust the diopter back and forth a few times then settle on the best position, set it and leave it. I almost never go back to change it again, except that I just got new glasses and had to repeat the process. Best of luck.
How old are you? Young people with perfect vision are able to focus from infinity to about 250mm. Old people like me can only focus at one distance (in my case, the distance is 1.5 diopters past infinity).

If you are a young person with perfect vision, you should be able to see your viewfinder in sharp focus with the diopter set anywhere from zero to 4 diopters. If you're a young person that needs corrective lenses, the numbers will shift but should be about the same range. You may be more comfortable focusing for distance but maybe not.

Grabbing the nearest Nikon with markings on the viewfinder adjustment, I can go 3 or 4 clicks with the screen in acceptable focus. I have to change it a lot if I'm wearing reading glasses but the range is the same.

I don't think it's important as long as you see the screen in sharp focus. With autofocus, even that isn't important.

I am 34 years old, hah.

As for the 4 diopters comment, do you actually mean 4 as in +/- 4.0? As in that a young person with perfect vision should be able to see to see the viewfinder of my D7000 (diopter goes from -3 to +1 according to the manual) clearly no matter what they would set it to, or literally from 0 to +4? Or diopters as in clicks of the diopter wheel?

As for the 3 to 4 clicks, I can kind of relate, for me it is more that it is a range of about 3 to 4 clicks that I always come back to where I cannot really decide which looks the most sharp (or that I change my mind on which one is for no apparent reason), I actually have to turn the wheel pretty far in any direction for things to become so blurry that I get distinct urge to change it because I (obviously) know I can get it better than that (if that even makes sense, haha >_<), but the jist of it is the same.

And yea, probably isnt that important and honestly, looking through a small optical element with one eye while focusing intently probably is just a natural recipe for faster than normal accumulation of fatigue. I did almost randomly stumble upon an interesting Wikipedia article though (even though I havent really checked the source material)


Thanks for your input in any case!
 
You're not taking into account that your eyes are not perfectly consistent. Not only does your correction change over time, but your eyesight fluctuates during the day depending on what you are doing with your eyes. Your vision is different when you first wake up than it is after several hours of driving, or several hours of close work at a screen. I see differently after I've been drawing for hours with natural media compared with working digitally for the same amount of time. So cut yourself some slack and use whatever diopter works best for you at the time.

Well, mostly the issue is that I cant really let it go and just use whats best for me at one time, because I have such a hard time finding out exactly what actually feels like it works the best at any one time, so usually I end up setting it to good enough and then avoid touching the diopter wheel like the plague, lest I might accidently change things, and a possibly slightly imperfect but familiar setting is better than a probably imperfect and unfamiliar setting, haha.

But point taken, and indeed. I dont worry about this very often, thankfully, but when I start to, I have a really hard time to stop worrying about it >_<'

Thank you for the input, I never even considered the fact that the factors you mentioned could change ones vision enough to possibly make small diopter changes noticable, even though Ive definitely experienced just the sort of things you mention.

It’s possible that you have astigmatism and the “optimum focus” varies across your field of vision. This is normally corrected by glasses, but glasses aren’t convenient for camera work.

If you haven’t done so recently, get your eyes tested. You are at the age when some vision problems start to develop.

I adjust the diopter based on the displayed text; I stop once the text are at their clearest. Seems to work for me.

Hmm, that is actually a very good point.

Yes, that is what I was going to suggest.

Should be easy to tell if the writing is sharp or not, once you have that there is no more than you can do.

General eye tests, including optical acuity, field of view, tests for glaucoma and retinal examinations are often carried out by optometrists. In many countries, these yearly tests are free.

This sounds like a good idea, the hard part is always the "let it go" part, haha! Best of luck to you as well :)

EDIT: (I wish I could choose more than one reply as the answer, but I chose this one for now).

I do the same thing. Left and right a couple of clicks. Which is the very best setting? Oh, this one is best. Um, wait maybe it's that one. In fact, I've also joked about it at after optometry exams. After a while, I'm not exactly sure which one is clearer! It's the desire for things to be just right; perfectionism. But, yeah, just like many things, you eventually have to just let it go.
 
Hi Swedra! Never a dumb question when it comes to digital photography. I'm glad to see the community is helping you out. Let us know if you have any other questions!
