How to align bonoculars


Cheaper binoculars may have no adjustment means for this at all (it is called "collimation"). Properly it should be done by adjusting the front lens in its seat, and quality binoculars have an eccentric ring around the lens under the clamp ring so that can be done.

Your Tasco probably does not have that, so look under the covering material on the barrels (it may be stuck down) for 2 small screws over the prism eg

Gross collimation can be done in daylight, but fine adjustment is best done with a point source like a star.

How do i tighten the swing action on my stiener safari binoculars?


These binoculars have a 10 yr warranty, so you may contact steiner (http://www.steiner-binoculars.com/) for repair for a nominal charge, however there is an easy fix: You'll need a small (about 1/4 in) screw driver.
1. remove the objective lens protector. This is the small metal piece on the binocular side that is loose, opposite from the eyepiece(part you look through). It appears impossible to "pop" loose from the outside, but if you slip your finger inside(try not to smudge the lense), you'll feel a significant ridge. You may be able to pull / pop it off with your finger, or a small handle.
2. Tighten the screw that is now exposed. Do not overtighten, just a little tighter than what it takes to keep it from "falling" on its own weight.
3. Pop the lens protector back on the object lens.

The eyepiece lenses have something on the inside. Can they be removed for cleaning?


  1. Carefully clean your binoculars by firstly removing any dirt or dust from the main body and straps using a soft microfibre cloth. Avoid the lenses at this point using any form of cloth on the lenses before removing all dirt and dust particles first could destroy them.
  1. Gently remove all traces of grit, dirt or dust particles from the lenses using a soft lens brush or canned air specifically designed for the purpose.
  1. Waterproof binoculars can be rinsed gently under a tap but be sure to use on lightly running water, avoid high pressure water as it could damage your binoculars.
  1. Gently remove any remaining marks using lens cleaning tools such as a lens pen or lens cleaning fluid and lens tissue. Do not be tempted to use kitchen towel or anything else lying around that is slightly rough and may scratch the surface of the lens, only use a lens pen, lens tissue or a lens cloth. Gently wipe the lens using a circular motion working from the centre of the lens to the outer edge. NEVER apply lens cleaning fluid directly onto the glass (always apply to the cloth) and always ensure that the lens cleaning fluid you are using is recommended for the type of lens coatings that have been applied to your binoculars (Do not use general household glass cleaning products or products designed to clean computer screens or glasses. Such products could destroy the lens coatings of your binoculars if used).

Was wondering if there was anyway to take the lens off my Newcon BN356/BN456 Binoculars to clean them?


Yes, First, when you take the lens off you binocular make sure you are in a very clean room.
All you have to do is unscrew them. Use a good lens clean that is anti-static. If you don't every piece of lent, dusty bugs, flaky shin, etc. will be attached to those lens. stewbison

Right eyepiece is crooked and stuck


The threads on the oculars are extremely fine. It sounds like yours are cross threaded (this is bad news).

Unscrew the lens all the way. Press gently against the mating surface and back off 8ntil you feel it "click." Then, VERY gently, screw it back in, stopping if it gets difficult. Cross threading is usually the death nell of optics...

I just got an old set of kalimar Model K7070 Binoculars ( 7X-15X35)from my father. They seem to have some type of water drop marks in the left lens. Are these worth trying to repair. I do not know what he...


The water drop marks you are seeing may be seperation of the lens coating. Most binoculars after WW2 have some form of anti-relective coating on the lens. This is applied to the glass surfaces in varying degress by various manufacturers. Its intended purpose is to reduce the amount of light that is reflected off the glass so that the image you see is brighter. Your windows at home that aren't covered actually don;t allow all of the light to come through!
What they all have in common is that the coating is applied onto the glass. Over time like anything that is stuck on or painted it can begin to peel off.
You could try asking a repair place if they caqn replace the lens but most likely they would need to change both so that they have the same coating. The binoculars are worth more for sentimental value than the cost of repair as a similar replacement set would cost as much. Zoom binoculars are not known for their optical quality. Often this 'watermark' effect doesn not interfere with the view. If your sentiments say fix them regardless do so. If not hold onto them as a keep sake.

Need to replace large lens cover for Swarovski binocular 10x42


Try Adorama camera in New York. They are good to deal with. Binoculars.com also used to carry parts but I have found since they sold to a conglomerate their customer service is wanting and i switched to Adorama. They also post international.
