Adjustable Objectives? Yes or no?

Looking into getting a scope around 3-9x, maybe 4.5-12 or something similar.

I'm not that familiar with optics. Should I get adjustable objectives? Is setting a parallax essentially just like adjusting the objective of binoculars? Do I need such features?

Thanks.
 
Very few 3-9, 3.5-10, 2.5-10 scopes are available with adjustable parallax. Most of those that are, are meant for shooting airguns and rimfires at short range.
Scopes that go over 10X often have PA or side focus, for shooting small things at long distance.

Optics Planet has some good info on this stuff, under "how to buy a scope" or something like that. Optics Talk (SWFA) has a faq section, too.

What is the intended use of the rifle?
 
.30-06 Remington 700. Mostly for target shooting. I doubt I'd need it for defense, but if ever I had to go long range, it'd be for that too.
 
Yes and not so much !!

On the bench and prairie dogs, I really like them. On hunting, not so much but kind of depends on what you are hunting. Most of my hunters do not have this feature. .... :)


Be Safe !!!
 
For target shooting, higher magnification and AO (or SF) make perfect sense.

Leupold VX-3, 4.5-14X40 AO. Burris XT bases for flexible mounting position. Warne Maxima or Leupold PRW or Burris Signature Zee rings.

The Nikon Monarch or the Bushnell Elite 4-16X would be options. The Leupold has more windage and elevation adjustment, in case you want to sight in at long range.
 
I will only purchase scopes with adjustable objectives for 100 yard plus target shooting, close in IMO not needed.
 
With a top end under 12x on a big game rifle being used under 300yds, I wouldn't bother.
Maximum parallax error for a scope set to 100yds fixed parallax is only 1.6" at 300yds, and that's if your head is way over, and the scope image is winking out. it's a very minimal consideration unless you're shooting small varmints.
 
Colvin:

If you are going to shoot prairie dogs at 300 yards or you are going to attempt quater inch groups at 100 yards you need an adjustible objective. On the other hand if your targets are deer of elk you don't need a AO. It doesn't hurt to have one in case you stumble on a coyote at 300 yards.

If you will shoot most shots under 10x and under 300 yards, it would have little to no effect.

Where you see it used most is shooting close 100-300 with a 36x scope where .001 matters and also shooting over 600 yards with a scope over 15x. Last case is for hyper accurate air rifles at under 25 yards at like 36x.

It sounds to me like you would be wasting your time.
