Sightron 111 Focus Problem

[Jdeere]

I have been experiencing focus problem that I thought was attributed to my eyes. I have had two people look through my scope and although not to the degree I am experiencing it -have both had focus issues. They look through the scope and it fades in and out of focus real fast - not constantly - just once while looking through it for a period of 15 seconds or so. My problem is it does it a fair bit. Like your eyes are trying to focus but can't. Assumed it was my 50+ yrs catching up to me. Anyone heard of this issue with either the Sightron or a high powered scope??

I have it on 32 X.

Thanks

I think you are moving your head a little bit and do not have your eye properly lined up with the scope.

One of the most misunderstood mechanical aspects of a riflescope is how to correctly use the eyepiece to focus the reticle. Here at Leupold, there are several kinds of eyepieces, but they all function similarly. All of them rotate—and in the process move in and out, changing the position of the eyepiece lenses in relation to the riflescope’s reticle. The reticle is the crosshair, or aiming point and the eyepiece’s primary role is to keep the reticle focused for the individual shooter’s eye.
So, to focus the reticle, point the scope toward the sky or another distant, light colored background. (If the scope is mounted on a firearm, ensure that the firearm is empty and rendered safe before performing this operation.) If the reticle is not crisp when you first glance through it, glance away, and turn the ocular lens about ¼ to ½ of a turn in either direction and glance through it again. The reticle will appear to be either more or less focused at this point. If it appears more crisp, turn a quarter turn the same direction and glance through it again. If it is less crisp, rotate a full turn the opposite direction and check again. Repeat this process until the reticle is crisp and sharp. If the eyepiece has a locking mechanism, lock it in place at this setting.
It is important to note that the reticle should not be focused while looking through the scope constantly. Your eye will compensate for the focus changes and focus will be very difficult to achieve. It is also important to note that the eyepiece focuses the reticle ONLY—not the target. Use the adjustable objective or side focus to remove parallax on the target (on higher magnification scopes). On lower magnification scopes, the parallax is factory set at 150 yards for most riflescopes, and shorter distances for other specialized products. (Rimfire scopes are set at 60 yards, for example.)
By properly focusing the reticle, your scope will provide a crisp, clear aiming point, and a sharp sight picture that is ideal for accurately placing your shots on target.

It sounds like your eye is working hard to focus on both the reticle and the target and that after a few minutes, your eye is fatiguing. I have a Sightron SIII 6-24x50 that I've recently put on my .22lr for some fun plinking. The effect is really noticeable when switching between targets at 25m to 100m, 25m is pretty much too close for the scope on higher magnification but y can push the limits a bit with the eye piece.

When I go on target at 100m, I'll use the side focus to make sure my view of the target is nice and crisp. Then I will fiddle with the eye piece until I feel that my eyes are focusing equally on the target and the reticle.

I will try Leupold's sky technique as described above.

How could you put such a lousy, low power scope on a high power .22lr gun? You better upgrade to SIII 10-50x60.

The reticle focus is controlled by the ring on the eye piece. If you didn't adjust it when you took it out of the box, it is WAY out... just a random factory setting.

I prefer to start with the reticle and dial it in looking at a white wall that is lit... DONT LOOK DIRECTLY AT A LIGHT OR SUN!!!!. A white cloud does the same thing.

When the reticle is sharp (there will be a range or adjustment where the reticle is sharp), look at a target then use the side focus to bring the image into focus. Small movements of the dial will give sizeable adjustment on your image focus.

Once the image is sharp, you can play with that small range of adjustment on the eyepiece to really bring it all together. This is the slight adjustment that other shooters might have to play with depending on how far from 20/20 their vision is vs yours.

The diopter range of the eyepiece is one of the widest in the industry. I have a few customers with seriously bad vision and cannot use other brands of scopes because the range of adjustment is not enough. They actually use the eyepiece as the "corrective" lense ... would bug me but it can be done.

If shooting LR, you will likely never have to touch the occular adjustment once it is dialed in. For shorter range, a tweak certainly brings it all into focus.

Hope this helps...

I don't have much to add regarding the focus problem described here other than to say that the focus control on the sightron has a very narrow window for a clear image. What really bugs me, and I'm not sure if its a sightron thing or just my scope, the focus ring is VERY difficult to turn. I'm talking so stiff that at -5 you have to remove your gloves and its taking skin of your fingers. I'm talking about an 8-32 by 56, Love the scope and will continue to use it for target work. Just not at all practical to take out in the field.
