Sorry to be the bearer of bad news but when you buy a mass production product this is what happens. now you have to find someone who can repair them. of course a few people can. but is it worth the while for them to work on it....no....shipping etc. would cost more than the price you paid. sorry larry@reichinstruments.com

How to hold binoculars properly


1. Remove the lens covers, if they are in place.
2. Set the diopter on the right barrel eyepiece. The function of this setting is to adjust between vision differences between your eyes if you are NOT wearing corrective lenses. Set to zero if you do have corrective lenses on (glasses or contacts). For proper diopter adjustment see this article: Binocular Selection Guide.
3. Most binoculars will hinge in the middle to allow for differences in the spacing between the eyes. Set the spacing to fit your eyes.
4. Adjust eye cups. Each eyepiece will have a means of maintaining the correct eye relief for the user. On quality binoculars the rim of the eyepiece will extend and retract as you twist the eyepiece rim. Move all the way in if you are wearing eyeglasses or adjust out if not wearing eyeglasses. You will know if they are set correctly when you look through the binoculars and check to be sure that the circular edge of the view should be sharp and not fuzzy. At this point we are not looking at any object in the view but rather the perimeter of the view. You may need to adjust the eye cups again to compensate. On lower cost binoculars the eyecup may only be a rubber lip that you either fold over (the "in" position) or out.
5 Raise binoculars to your eyes and use one finger to adjust the focus wheel on the center shaft between the two barrels, until the view is in sharp focus. If viewing for extended periods you may want to keep your elbows down near your side as this will increase comfort while viewing.
Final safety tip: Do not look at the sun through binoculars.

Many people enjoy observing nature with binoculars. Having them handy is key. Hunting, astronomy, marine use, and stadium sports are a few more activities where having a pair of binoculars can make a real impact to your experience.

Vivitar screw mount lens, Nikon D-80 camera. Is there an adapter for this?


The M42 mount was used by several camera manufacturers, most notably Pentax. Nikon is not one of them.
Vivitar made many lenses with a T-mount. This consists of a screw mount on the lens and a suitable adapter, depending on the camera body. This allows a lens to be used with different cameras simply by changing the adapter.
If your lenses are T-mount, then yes, there are adapters available. One source is here.
Be aware that you'll probably lose any metering capability when using any lens with this adapter. You'll have to use a separate light meter or else view the resulting picture on the display and adjust the exposure appropriately.

8x25 minolta compact bionoculars center focus knob will not turn. Have taken screw off center knob and removed 4 rubber strips on bionocular body and looks like allen? screw underneath. No obvious way...


They don't make these things easy to take apart, or fix. Here's your best shot- take it into a camera repair shop, and see what they say. Some tech might know what you have to do to get it apart, or if it can come apart without damage or special tools.
Unfortunately, only the repair techs know how, and there aren't too many (if any) of them, since they often just charge a set amount and send a refurbished or new pair to the customer.
Wish I had a more specific answer, but good luck to you, and with just a bit, you'll figure this out.

I bought these for my husband. In trying them


Difficult to answer specifically without knowing the model. But binoculars are designed to view objects in the distance. They all have a limit as to how close they will focus based on the magnification and design. Objective lenses that are far apart such as on a porro prism binocular will not focus very close. The nature of the design of having the objectives further apart than the eyepieces doesn't allow it. When trying to focus too close the image will appear blurred and double. That is the nature of the design. 9 feet or 3 metres is considered quite close to focus a binocular and is usually for a model designed to do this such as a roof prism where the objective lens and the eye lenses are inline. A specialty binocular such as the Pentax Papilo will close focus to 50 centimeters. It has been designed so that the objective (large lenses) lenses converge.

Take into account when focusing that binoculars are also designed to compensate for differences in each eye. One of the eyepieces either right or left will adjust seperately. For binoculars with a center focus ring. First focus using the center ring with one eye covered. The eye that should be covered is the one that doesn't have the adjusting eyepiece. When the image is clear close the eye you have just used and leave the center focus alone. Focusing on the same spot look through the eyepiece that adjusts and turn the eyepiece ring until the image is clear. Now all you have to do is focus using the center ring only as the binoculars are adjusted for each eye.

Some binoculars do not have a center focus and each eye will adjust seperately.

Dropped new Celestron Skymaster 15x70 binoculars. Nothing appears broken, but now have two images. Can I repair this. and how? Thanks. Dan


Don't "unscrew" the binoculars. there are no user servicable parts inside. the collimnation adj screws are beneath the rubber boot just under where your index fingers rest when looking through the bino's. use a jewelers screwdriver to tease the boot up and stick a small nut or something in. then put the binos on a stable surface and play with the screws a bit while watching the images. you can get them pretty close this way.

One of the eyes got broken when it fell out of the tree stand


chances are when they dropped other optics moved as well, that means they will have to be realingned. i dont know what they cost you but i think its a done deal. sorry for that ,but there is so much cheap junk on the market today that it makes sense to just buy a new one as a good optics teh would cost at least $80.00 per hour to repair....larry@reichinstruments.com
