even though there are numbers from 20-200 on the knob, it seems it is mearly a focus and NOT magnification How do I increase magnification?

My experience is that it adjusts the focal length and this the magnification increased, but you must move the subject closer or farther from the end. You may have to move the small object into the window if it comes into focus. Depth of field gets very tight at higher mag.

The push/pull refers to the 600-1300 magnification. Loosen the knob and you can extend or shorten the lense. Once you have the proper magnification, there is a locking knob that tightens and holds the magnification. In order to focus I use the black ring under the Opteka logo with the inner focus marking. It takes some practice to get a great picture. I would also recommend getting a tripod to support the weight. If you have other questions, let me know.

Hi Donna... Don't know what your problem is. Maybe out of focus? You can adjust focus by removing the black cap by unscrewing it. It is threaded into place. Inside, you will find two adjustments, field of view, and focus. They work together. Changing the field of view changes the focus. Start by focusing, then adjust field, and then refocus. Hope this helps, directions are terrible. Well, there aren't any, actually.

The adjustment knobs have lock rings you can turn by hand so it will stay where you set it. If you want to change settings loosen them then lock back. I have four of them on 22-250,25wssm,300wsm,and30-378 mag great scope works great.

When I ordered I had an option to select the magnification. Try another gamma ray search and see if other gamma ray products come up that give you that option. Hope that helps.

You could by a rail rig to mount to your camera which raises it out of the way of the knob but what I've been doing is just pulling out the tightening knob and adjusting its postiin on the screw. It's hard to explain in words but you just pull out on the knob and adjust it postion on the screw until it's tight. Lemme know if that helps

The focus is infinite. The closer the lens is to the object, the higher the magnification. It will also work on some android devices. A magnetic dial indicator base from harbor freight can be a good stand.

I am Sorry i forget to Include this Information with My Response! Be Sure to Include a f-Stop Increase to being thing into Focus Also! This is Very Important Too! It is Something You Have To Experiment with to get Correct! Not Hard to Do, Just Use Live View on your Camera and Play with it from there! This Aspect is Very Tricky for Focusing and Experience will be Needed to some degree!

There is a way to focus but it will be a trial and error because the image on the srceen is not very clear. If you still have the owners manual, it gives a step by step on how to do it. I was able to focus mine rather easily. Good luck.

I don't think you can. There are no knobs or levers on the machine. It seems that the speed is proportional to the amount of light? I rotates fairly slowly, since it's a display stand for jewelry.

You need to zero your sight first without magnifier (slide away). Then you need to adjust magnifier.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

Thank you for shopping with us. Focus dial should be right next to the lens. In that case, you should turn the dial 10-20 times.

Yes this headband magnifier will be in good focus at 18 to 24 inch range. I am happy with mine. I spread butterflies using mine. I have no focus problems at 24" or much closer. For the price this magnifier is as good or better than much more expensive one.

No, it's a fixed magnification. You can adjust the focus by getting closer or farther away from the object you're magnifying.

I have to agree that the markings on the knobs are a bit difficult to see if you are older and need reading glasses....i.e I have to have my reading glasses on to see the numbers.

It's probably working fine but you have to realize two things, it's designed for close work so if you have it too far away from whatever you're trying to view you're going to get the out of focus white circle. The second is if you have it close to or on top of whatever you were trying to look at you need to focus with the ring on the bottom. I thought mine was broken for a while until I figured out how to get it to focus. Finally you can also shift the focus when adjusting the magnification ring on top. If you change the magnification you will also need to refocus. Hope this helps
