Do most/all scopes have a focus adjustment?
May sound idiotic, but I've only handled a few, so please bear with me.
I want my carbine to be configured for ranges from CQB to about 200 yards. For several years a red dot used to be adequate for this -- even the irons long ago if was daytime -- but progressing eye degeneration is making them less and less feasible. I've tried several different models of Aimpoint and Eotech, but currently with none of which can I obtain a precise enough image. (Search thread titles for "astigmatism".) Little comets, grape clusters, etc. are typical.
I've recently handled a couple of friends' 1x4 scopes which had a focus adjustment. I had to change the settings a lot from what their owners had them on, but once I did what a difference! The reticle became sharper than anything I've seen in 10 years.
I've been looking around the web at different 1x4's, but focus adjustment is never mentioned as a feature. Is that just because it is standard on every scope out there?
I realize there are other trade-offs between red dots and scopes, but at this point having an image I can can clearly distinguish would be an end unto itself.
Thanks for aiding the un-educated.![]()
