In order to put the experts in to perspective and  without quoting anybody,  here is some info I've collected on this site about parallax:
  • Parralax is the way the cross hairs align with the target. Which is to say, that if you are looking through your scope, and the parralax isn't set just right, any shift of your head will change the POI of the cross hairs on your target. In extreme condition it can cause you to not even be able to hit the paper, let alone get a good zero.
  • Scopes with adjustable parralax have a shallow depth of field, which means that they have to be re-focussed whenever the distance to your target alters by a few yds. For this reason engaging moving targets and or targets at varying distances in a hurry can be a problem. Having said that lots of guys use them even under these conditions.
  • For most hunting situations AO or SF are unnecessary distractions that will just slow your shot while you fiddle with the scope. But once you get beyond 10x (7x for a rimfire) it's pretty much a must have item. I also consider parallax adjustment a must for target shooting

The context:

 
For  deer hunting at distances from 25 to 250yards all conditions (Deep woods and agricultural fields)
 
 
The scopes
 
Zeiss Conquest
 
  1. 3X9X40
  2. 3.5X10X44
  3. 4.5X14X50

Our choice of scope would be directed towards the 4.5X14X50 to allow more precise bulleye adjustement at long range and easier long shots on the field..

 
Help wanted here:
  • Zeiss says that the 4.5X14X50 is parallax free at 30 yards..Does this mean that we have to play with parallax from 30 yards up ?
 
  • If one uses this scope for hunting and spots a deer at 20 yards and  then another one at 75 yards and then 35...Does one have to adjust is parralax every time he aims at a different distance ?
 
  • With the Zeiss Conquest 4.5X14X50: in a hunting situation, how often and when does one need to play with the parrallax knob?

 

  • Wil this scope be a handicap in the woods ?
 
Thank you  in advance for your contribution and for helping us make the right buy.

  • Zeiss Conquest 4.5X14X50  Will this scope be a handicap in the woods ?
  • YES  in the woods you want lower power like a 1.5-6x.   Where a 4.5-14x scope is more useful is at extended distances like 200 to 600  yds.  If you are hunting in the woods look at this Zeiss Conquest:

    I have used a Nikon Monarch 4x12x40 AO in the woods some and if I set the objective focus (parallax) between 50 and 75 yards I have never had any problems seeing or hitting game down to the size of rabbits.  In my experience the AO focus tends to be more forgiving (less critical) in the better quality scopes.  If your hunting deer from 25 to 250 yards any good 3x9x40 will be plenty.  In fact the Zeiss 2.5x8x32 Urimaginaryfrnd posted would be an excellent choice.  I have one on a X-Bolt .308 that I will use for the same type hunting you intend to do.

    I think that the biggest problem with the parallax adjustment not adjusted correctly for the target distance is the fact that the scope is out of focus. In other words the target will be blurry. For hunting larger animals an out of range parallax error will not cause one to miss the target.
    If one is hunting field mice at 200yds on the other hand, then an incorrect parallax adjustment and poor cheek weld may cause you to miss your trophy field mouse.
    To keep adjusting the parallax or "focusing" the scope during hunting is not allways practical.
     
    Zeis gives the spec as down to 30 yds, which may be of value if engaging close targets. My Leupold for example will only focus down to about 50yds. In certain sports discipline we have to engage targets at 30 yds, which means I am aiming at a slightly blurred target. The parallax error is so small though that I do not have any problems hitting the target.
    Yes, this means you can focus from 30 yds and further, but not closer. So an airrifle shooter will not choose such a scope as he shoots at 10yds etc.
