Parallax and focusing scope differences

[lennyk]

It possible for some scopes to be such that when focused properly the parallax is dead on and doesnt require extra focus/objective fiddling ?

or in other words are there scopes which to achieve good parallax setting will require adjusting the focus slightly with no discernable change in image sharpness ?

if its not real clear whack it on the side of a tree .. usually does the trick for me lol ....

most of my better scopes are all rated for parallax free, down to a certain yardage, below that yardage they are blurry, not clear

but from the advertised parallax minimum out to infinity they are clear as a bell,

its only when I want to shoot 10 to 50 yards it seems I need a scope that adjusts for parallax 

most manufacturers state in the scope specs that a scope is parallax free down to a certain yardage, rules out a lot of scopes if you want a 

clear picture at 20 yards

Your question is nebulous. Try to rephrase and give a example of your problem.

 First off the ring next to your eye,diopter ring is to focus for your eye,.the AO is to focus on target=paralllax is set for a given distance....and the diopter set for your eyesight.

Many non AO scopes are set for a given distance...they are usually 50-100yds...even if they are perfect does not mean you will be able to see target good...unless you adjust the diopter ring to your eyes.......

I too can not understand the question enough to offer and answer.

I think I understand Lenny's question to mean this:

"If a scope image is completely sharp/ in focus — is it possible that there is still some parallax error left (that would require to adjust the focus/parallax a little)?"



Lenny, please confirm — or explain a bit more.

I'm not sure if I understand the question, but, it is possible on some less expensive scopes (and even some relatively expensive ones also!) to adjust the parallax out and not have the picture clear, and vice versa.

I prefer the bed post.

Yes, a good quality scope should.

To further answer your question Google "parelex vs focus." There are several good articles on the subject.

My apologies for the ambiguity, but yes this is what I mean.

For example if 2 different persons used a scope and dialed in the focus as best as they could, is it possible that say the yardage marking would be different as well as if any difference in parallax if another person were to use the scope and move their eye around.

The better quality upper end scopes are more critical and need to get the parallax adjustment perfect for the sharpest image.

Sloppy or cheaper quality scopes don't need perfect parallax adjustment. 

I recall reading these may be better for hunting situations where the parallax dial don't need to constantly be fiddled with and image stays clear with great eye box forgiveness. You set it then the next guy probably dont need to adjust any thing. Such as this one.

Many members swear by them. I was shocked for how nice being so inexpensive.

May not be good for range finding because image stays clear with little parallax adjustment needed.

I have noticed this issue as well on some AO scopes being perfectly focused but still have discernible Parallax, the diopter adjustment is for the crosshairs focus I have clear crosshairs clear target but noticeable parallax. I believe this is a scope quality issue and those people who do not understand your question probably have better scopes. I have not found any way to solve this yet. Until I can afford a better scope I do my best to get repeatable eye placement, cheek weld. Adjustable recoil pads and cheek risers help eye placement.

I have that Centerpoint scope, I have no complaints at all. It will stay here as an extra, just in case scope and is a great deal for a beginner. I have heard of people getting bad ones, but mine is great. The small diameter UTG side wheel fit with no mods too!
