Hi folks. New to the sight here.  I am looking to buy my first decent quality scope.  My question is this.  On the El Cheapo scopes that I have owned in the past, the adjustable objective seems to act as a focus for the image seen through the scope.  I thought this was designed to correct for parallax error only.  Why does it act as a focus?   Also, why don't rifle scopes have a true focus like a telescope might?  Or does the A/O act as more of a focus than I origianlly thought?   Like I said.  I am a optics idiot..  I tried the search feature and read a lot of good material but I only added to my confusion.  Anybody want to put me on the right path?

Thanks and glad I found the forum.

Kevin

The AO is the focus or parallax adjustment.

If your scope has a "quick focus" or an eye piece focus, this brings your reticle ONLY into focus.

 

If your scope doesn't have an AO or side focus, it's parallax is preset @ the factory.

 

I hope that and the thread above helped you out.   

 

Welcome to OT!!

Glad your here.......

Thanks Cheaptrick.  Glad to be here and thanks for the reply.  I had read that thread but I guess I didn't realize that the adjustable objective worked to correct the parallax error and focus the sight picture.  I guess they are one in the same then?
