All,

Leupold makes this scope in AO, side focus, and no-manual focus. 

If I am putting this on a rifle to shoot to a max of 800 yards, is parallax in the no-focus knob scope going to be an issue at 14X? 

The scope is going on a mountain rifle for an overseas hunt.  I need a light weight scope with the ability to help me stretch out to 700-800 yards if my body can't get me any closer. 

Thanks for the help.

Jeremy

Game animals were probably harmed whenever I did whatever it was that I did.

I would say for that magnification and range I would want it adjustable.

My first question is what do you consider lightweight?  The other is just an observation......my hunting buddy Big Al has been using that 4.5-14x40 VX3 CDS (no parallax adjustment)  for the past couple of years.  At higher mags it is not very friendly to use, i.e, the eye box is very finicky.  It is not hardly possible to refocus on the target at those long distances and keep the reticle sharp.  For these reasons I much prefer the 3.5-10x40 VX3.  I'm not a habitual turret twister though either, but I do tinker with, and like the CDS dials and adjustments.

Lightweight, to me, is a scope in the 10-15oz area.  The Leupold offerings seem to be the lightest in the 4.5-14 power range.  I have used a lot of 2.5-10 power scopes, and they don't work as well for me past 500 yards. 

One of the issues that I will be dealing with is not knowing which animal to shoot while a non-English speaking guide is trying to direct me.  I want to be able to judge the animal through the scope if needed.  That is why I am leaning toward higher magnification. 

Other options?  Maybe the Swaro 4-12 Z3?

I am open to any ideas.

Thanks.

I'm not a huge fan of the reliability of the Z3 (SwaroA), as I've had one go down on a hunt, and so has my hunting buddy I mentioned earlier.  That light a scope, doing what you want to do, will be tough.  You should probably fiddle around with that 4.5-14 VX3 and see if it works for you before you just take my word for it.  I've had great luck with a 2-12 VX6, but it's a bit bulkier and heavier.

Howdy, Wapiti1.
For me, adjustable focus would be nice to have for precision shooting beginning at 10X and a real necessity at magnifications at 14X. Any AO or sidewinder will add at least 2 oz. or so. Everything in optics design and use is a series of compromises.

I've spent the past few days evaluating yet another hunting scope that tops out at 10X, comparing it to those I already own and have put them all through their paces. Alpha to midrange glass and prices, but to varying degree, they all exhibit the same characteristics regarding precision of focus, mirage (which also starts to affect precision at 10X,) etc. The effects noted are small at 10X, but increase with magnification.
