Adjustable Parallax - How Essential?

Interested in peoples thoughts on the following: how essential is adjustable parallax on a 2.5 - 10 scope that will only be used for deerstalking out to 250yds?

Same answer from me....
Not That essential I think. On my 3-12x50 Zenith I do miss it if shooting at longer range smaller targets, clarity won't match my Zeiss Conquest with parallax.
Anything over 12 mag I prefer parallax adjustment.

I have leupold with adj parallax, it is left at 100 yards.

Airguns used at 30 yards or so do benefit from adj parallax. I now used older nikko/tasco scopes and adjust them myself.

The post above is telling as the benefit of parallax on a scope that goes to 10-power and above within a woodland setting is far greater than when using in the 100/200 yard range. So what I'm trying to say is the ability to get a delightfully crisp sight picture at 50 yards (short distances) when the zoom is cranked above 6-power is the defining need for this feature IMHO.

Which brings me to a long-standing gripe with the Big 4 scope manufacturers: They should be offering parallax adjustment well below 50 yards on their top scopes and its only in the last 12-months with Leica's introduction of the Amplus 6 that this consideration has been nailed.

Technically you are certainly right. A crisp picture at 50m is usually not possible w/o an adjustment.
But this is not the objective. The closer the target the easier it is to engage it even with a blury sight picture. This is for normal stalking.

If the scope sits on a .22lr it‘s certainly a different story.

This opens a can or worms as my preference of not having a blurry sight picture at c50 yards (or any distance with c£2K scope) when at 12 or above power brings with it the argument of why do you need more than 4 or 6-power in a woodland setting!

i have a S&B 2.5-10x56 and have no parallax issues. Most of the time it's on 8 anyway but if it's close I wind it down.

On the sightron it's required although mainly for add on's

Every variable power scope should have adjustable parallax in the form of a 'side focus' dial.

Anything with an objective lens size over 40mm without said feature is going to be wanting at 300m+, but then again most don't shoot that far ;)

Those who never use parallax probably don't know how helpful it can be, especially in woodland shooting. Focus your target, crank up the magnification then slowly turn back the parallax to lowest setting. If there is any grass or twig or fence wire in the line of sight it will become crystal clear, guess the bullet path from that. I have repositioned several times after seeing a twig in the way that I didn't see initially.

Unless I’ve missed it, no one has mentioned ‘parallax’ error. If your scope is fixed parallax (usually 100 yards), and you’re shooting at shorter ranges, eye position behind the scope is critical to avoid poi issues; this is less significant at distances over 100 yards as the effect is non linear. Parallax error is frequently the cause of frustration particularly for air gunners who’ve fitted a fixed parallax scope that’s set at 100 yards and intended for centrefire use.
On lower mag scopes there is a greater depth of field ie, the image remains sharp over a wider range of distances. However, just because the image is sharp parallax error hasn’t been eliminated.
So its down to what you intend to use the scope for. If it’s for 75 to 200 yards and low mag; you probably don’t need adjustable parallax. If it’s for a wider range of distances, and particularly short range or for focus sensitive higher mag scopes, you’ll need adjustable parallax.

As ttocs says parallax error equals error on the target , if your only shooting 100 yard ish !!! You’ll be fine with fixed at 100 yard ish !!! Some good videos on the subject but get out into field spend some time just looking at various ranges and rock your head up down and you will soon realise the importance of parallax adjustment

Well I'm not talking "error" in the sense of POI issues but rather enjoyment of the sharpest possible image at the lower end of target engagement distance.
