If someone has this scope please tell me if when you look through yours over 6-7x power at under 100 yards if your focus gets slightly poor. I have two and both do it real noticeably at 50-80 yards.  They are brand new.

I have 3 ,,no worries ..
Maybe check your manual focus setting , perhaps if it is still set at the factory setting, it may not be right for you

Hum, between the 4000/4200's, I own 6 and I have not had that problem. What I do to set the focus correctly, is put the scope on it's highest power setting and then focus the reticle. Also, I try to do this toward the end of the day with not to much sunlight present. The pupil of your eye is more dilated at his time of day and gives you better depth perception.

 Actually, the pupil of the eye is identical in function to the aperture of a camera lense.  The more constricted the greater the depth of field.  This has actually been studied in the human eye quite extensively.

What does focusing the reticle have to do with it?
 
I tried this for over an hour about three times.  I could make it very slightly worse but no better.
 
I am guessing (and this is a wild one) that the parralex is set at infinity, not 100 yards.
 
back to my question:  Could someone dial their scope up to 10x and look at something 75 yards away then dial it down to 6x and tell me if it's the same?
 
I can read license plates at 90 yards on 6x that I can't read on 10x
 
I have done everything as per the instruction manual and got no where.
 
personally, I think it's a piece of junk compared to my Leupold

I have 3 of these scopes and can tell you that you need help in learning to focus.
 
The parallax is set at 100yds but that's not a focus issue.
 
Leupold scopes are very different from the high end Japanese optics and you need to slow down and figure it out.

Was at cabelas tonight to buy the 4200 4x16x40 and compared it to the Burris Signature 4x16x42.  When looking at the other side of the store on the higher powers, set at 100, the focus was hazy and fuzzy thru the 4200 yet crystal clear thru the Burris. Needless to say I walked away with the Burris.

I have posted in another thread this same delima concerning the Bushnell 6500.  Maybe Bushnell needs to give more extensive explaination on how to use the focus mechanism if in fact there is something that we don't know or can't figure out.  I don't want to go through the trouble of sending my scope back if it is me that is doing something wrong.  I have not messed with the parallax setting at all just the ocular adjustment and I can't get it to focus on closer objects on anything over 8x.

The ocular adjustment has absolutely nothing to do with bringing the image in focus.  It has only one purpose: to make the reticle look sharp.  You should never use the ocular adjustment to bring the image into focus.

Here is what you should try:

First, rotate the ocular adjustment as far out as it will go.
Then looking at the sky or some other very distant uniform scene, slowly bring the reticle into focus using the ocular adjustment.  Occasionally, glance away from the scope to let your eye rest.
Once the reticle is as sharp as it can be, use look at some object reasonably far away (50+ yards) and bring it into focus using the parallax knob.

Generally, once you set the ocular adjustment for your eye there is little to ever mess with it again.  For bringing the image into focus, you should be using the parallax adjustment knob.

 Thanks.......now that is good and direct help.  I will try that before I send the scope back to Bushnell and keep the forum posted as I see that some others have had similar problems with their Bushnell scope.......Doug

ILya, thanks for your input as usual. Do you have any thoughts on what could be the problem getting these non-AO/SF 4200's into proper focus? Do you think they might have defective scopes which are causing these focusing issues?

It is hard to say what the deal is with 2.5-10x40 that does not have aprovision for adjusting focus (AO or SF).  Hwoever, it is important to note that the if your reticle is not in focus there is a good chance that your image will not be focused either.  The remedy, is still the same:  use the ocular adjustment to get the reticle perfectly focused as I explained in a post above.  Then find an object 100-200 yards or so away and look at it.  If the image is not clearly defined, then it is likely that either the scope is defective or your eyes just do not agree witht the 4200 (that would be rare, but it does happen).

 BINGO.......that did it!  All of my scopes are for hunting close terrain in Virginia and are all of lower power.  No higher than 9x.  I have never had a scope with parallax adjustment and thought that it had nothing to do with the image and everything to do with the reticle.  Today I know differently.  I am able to bring the image into perfect clarity by using this parallax adjustment.  Thanks for the great help and I will also post this on another thread......Doug
