Rifle Scopes Reticle looks great regardless of diopter setting? SWFA 5-20x55mm HD

[notblake]

Hi all, I recently mounted a SWFA 5-20x55mm HD on my SCAR 20 and so far I have been very pleased with it so far.

There's just one quirk (I can't really even call it a problem) so far that I'm struggling with: The reticle always looks great.

On all the other scopes I've owned, adjusting the diopter made really meaningful impacts on the reticle clarity. IE it would go from blurry, to sharp and then blurry again over the range of adjustment. In all my other scopes there was a very narrow window (call it 1/2 a revolution) in which the reticle would be optimally sharp.

The adjustment on the SWFA 5-20 goes from Pretty great, to perfect, and then back to pretty great. The thing is that at every position from the minimum and maximum adjustment, it looks about equally perfect. I can have my eyes closed for and immediately upon opening the reticle is tack sharp including the tiny dots inside the diamonds of the reticle which according to SWFA are 0.015r in diameter.

I guess this is a good thing, but I'm also second guessing that I'm doing everything right? Or that maybe there is something jacked up about the scope?

The rifle is pointed at a wall that is very well illuminated, I'm at full magnification (20X) and the parallax correction is set to infinity. Picture of the setup is below.

I guess I should just set it somewhere in the middle of the perfect range (which is literally like 20 turns wide), lock it down and call it a day?

Should I be concerned at all? Maybe this is how really good high magnification optics are? It's my first rodeo with high quality non-prism optics (prisms obviously have no diopter setting).

For reference I'm following the instructions in this thread: https://www.snipershide.com/shootin...rifle-scope-a-simple-psa-on-diopters.6252841/


Thanks!

I have a related question. When I start my lawn mower by pulling the cord hard or soft it starts perfect either way. Some of my older mowers needed the pull cord yanked at just the right speed. Should I be concerned that my new mower starts no matter what?

Also, pink walls?

That's a pretty poor analogy since the one task a pull-starter has is starting the mower. It has a binary modality.

A much better analogy would be: "regardless of how I set timing advance on my lawnmower it runs just as well." This is because in both cases something that is supposed to adjust the way a mechanical device operates appears to have no or very little effect.

Walls are maroon, you're seeing splashback from the work and spotlight not that it matters.

Try setting the diopter on minimum power. I read in the ZCO thread that’s how they recommend setting it. I’ve done that with a couple scopes and it seems to work well.

As to why the adjustment doesn’t make much difference I have no clue. It could be your eyes can adjust the focus so quickly you don’t notice much difference. ?‍

Your wall isn’t maroon. It’s pink. ?

I would take a natural-lighting photo of the wall in question, but I'm quite aware that this is now a fake moon landing scenario where people will say its photoshopped, or that isn't actually the same wall, or its clearly a soundstage, or I repainted the wall. So screw it; the wall is pink and the earth is flat.

Any input on the scope? Just set it and forget it?

You'll need to record a video with the wall being lit up as it is on the picture, then turning off those lights so we can see it's natural color.

On a more serious note, I would assume that your eyes are maybe adjusting and making it seem as if the reticle is perfectly focused. I can adjust the diopter on my scope to where the reticle looks so blurry and out of focus but if I stare at just a tad bit longer or look at it really focused, my eyes will then adjust to where the reticle looks good. Perhaps your eyes are quick enough to focus? Although if you're closing and opening your eyes for a split second as you go through the diopter adjustment that shouldn't be the case because you're not giving the eye enough time to adjust. So, maybe you have super focus eyes lol.

The other thing I can think of, the diopter adjustment range is really small on that scope and you simply got lucky that it happened to be right where the reticle gets focused up really nice for you.

Im just picking about the wall. Having some fun.

I wouldn’t worry about it. Set it for now. When you get to the range you can fine tune it if necessary. I have several of these scopes and they are great.

Sorry for the poor analogy. I was in a rush to make fun of your ridiculous post and your pink walls before everyone else.

Also, there is a forum on here specifically for stupid questions.
