I have a pair of pentax 10x42 DCF HRc binoculars that will not focus properly througn the right eyepiece. Just wondering if this is a common problem and is it worhtwhile getting repaired


The binos will rack focus both at the same distance, you need to rack focus left side to distant image with left eye only, then turn diopter focus to focus right eyepiece. Diopter focus is thinner wheel behind focus wheel

I see double image unless I take the lens as close as the binoculars can go


thats how binoculars are. Yours in this case is really strong. the closer you are to something, looking at it, the more magiflyed you going to be. try view things far a distance, really far away. no more double right?
Everything you need to know to become an expert:
on this website: http://www.chuckhawks.com/binocular_basics.htm
It is surprising how many people do not know how to focus binoculars correctly. There are two common focusing systems used in binoculars.
The first is individual eyepiece focus. This system is simple to understand, and easy to manufacture. It also lends itself well to sealed optical tubes, and thus is usually the focusing system used for waterproof binoculars. Individual eyepiece focus means that to focus the binoculars to your eyes, you simply focus the left eyepiece to your left eye and the right eyepiece to your right eye. There is no centrally located focusing mechanism. It is done like this. Look at something in the distance. Close the right eye (or cover the front of the right binocular), and focus the left eyepiece to your left eye. Close the left eye (or cover the front of the left binocular), and focus the right eyepiece to your right eye. You are finished, until you need to look at something at a different distance, in which case you need to repeat the process.
Because individual eyepiece focus is time-consuming, center focus is more common. Unfortunately, very few people understand how to correctly use center focus binoculars. Here is how it is done. Aim your binoculars at something in the distance. Close the right eye (or cover the front of the right tube), and focus the left side of the binocular to your left eye using the center focus control, which is concentric with the pivot shaft between the binoculars. (Note: the left eyepiece itself does not focus on center focus binoculars.) Next, close your left eye (or cover the front of the left tube), and focus the right eyepiece to your right eye. DO NOT touch the center focus control while you are focusing the right eyepiece to your right eye. Now you are finished. What you have just done is adjust the binoculars for your individual eyes. (Practically everybody's left and right eyes are different.) From now on, you only need to adjust the center focus control when you look at things at different distances. Center focus is faster and easier to use than individual eyepiece focus, once you have initially set the binoculars for your eyes.
Binoculars are commonly described by using a pair of numbers, as in "7x50" or "8x25." The first of these numbers refers to the magnification offered by the binocular. Magnification is why most people buy a pair of binoculars. In the examples above, "7x" means the binocular makes whatever you look at appear seven times closer than it does to the unaided human eye. "8x" means the binocular makes whatever you look at eight times closer than the unaided human eye. "10x" makes things look ten times closer, and so on. The first number used to describe binoculars always refers to their magnification. Common binocular magnifications are 6x, 7x, 8x, 9x, and 10x.
There are also variable power (zoom) binoculars, such as 7-21x50. These almost always perform much better at the low power setting than they do at the higher settings. This is natural, since the front objective cannot enlarge to let in more light as the power is increased, so the view gets dimmer. At 7x, the 50mm front objective provides a 7.1mm exit pupil, but at 21x, the same front objective provides only a 2.38mm exit pupil. Also, the optical quality of a zoom binocular at any given power is inferior to that of a fixed power binocular of that power. In general, zoom binoculars are not the bargain they seem to be.
Remember that everything (including movement) is magnified when you look through a pair of binoculars, especially your own shakes and tremors. So the higher the power, the harder it seems to hold the binoculars steady. 6, 7, or 8 power binoculars are easier for most people, even those with very steady hands, to hold reasonably still. The higher powers sound like a good deal, but often result in jiggly, blurred views. This is why 7x binoculars are chosen by so many experts, including the military.
Power affects brightness. Other things being equal, the higher the power, the dimmer the view. And power also affects the field of view of the binoculars. Again, everything being equal, the higher the power, the smaller the field of view. So, as you can see, power must be balanced against other desirable characteristics when choosing binoculars.

B/L ZEPHYR 7X35 HARD TO ROTATE CENTER KNOB FOCUS?


Over time the grease in the central pivot shaft hardens to restric the rotation of the focusing wheel. Heat from a hair dryer combined with a little WD-40 can ustally re-soften the grease permitting the wheel to turn slightly. Working the wheel back and forth over a short period of time should get it to work again easily.

Stiff focus wheel


The number one rule is to never use oil on a binocular!!
I suspect that the multistart thread on the focus arm carrier, which is internal, has become gunged up. This is not an easy repair for a beginner. The rubber has to be removed from the body of the binocular before you can even start to take them apart to determine the fault.
Like any bearing or gear system, the part would have to be cleaned with a degreaser, then reassembled with new lubricant.

There is some sand or dirt under the focus knob that makes a noise when the knob is turned. How do you take the knob off to clean . Thanks


There is a central aluminium decal on the focus knob. CAREFULLY prise it off using the tip of a sharp knife trying not to distort it (it's hard to panel beat a small bit aluminium!). Once off you should see a central screw or two screws that hold the focus wheel in place. Remove the screw(s) and the focus wheel noting the orientation of the focus wheel to the body. Use a dot of Liquid Paper to show registration. You can then clean around the focuser and the inside of the focus wheel before reassembly.

Differnt focus for each eye?


All binoculars (except some really cheap rubbish) have a different focus for each eye. There are two types. Binoculars that have two individual eyepieces that turn and no center focus wheel. This is common to military, astronomy and binoculars used at sea.

The other is the usual center focus binoculars that have a wheel between the two barrels. They will also allow either the left or right eyepiece to turn to focus for one eye. The reason is that manufacturers take into account that each eye is slightly different.

How to focus my Zeiss 10x40B TP binoculars


Your binoculars are known as the Zeiss Classic or what was once known as the Dialyt. They focus differently from the usual binoculars like those mentioned. The rear wheel is to focus both binocular barrels while using them. The front focus wheel is adjust the right eyepiece to suit your right eye. Binocular manufacturers take into account each eye is slightly different. To focus the Dialyt...First close your right eye and turn the rear wheel until the image is sharp in the left barrel. Leave the focus wheel alone. Now close left eye and adjust the front wheel until the image is sharp for your right eye. The image should now be clear and in focus for both eyes. It should not be needed to use the front wheel from now on. The rear wheel is what you will use to change the focus from near to far objects.

Binoculars Stiff to focus


if they continue to get stiff then eventually the 3 set screws that hold the focus wheel loosen, and you will have no focus capability, its rare with zeiss but sounds like they should be regreased. the problem is to regrease you have to take completely apart as it is internal focus.if i can help any further contact me@ larry@reichinstruments.com

Double image


The distance between the centers of the eyepieces of your binocular must be the same as the distance between your pupils. This distance is adjusted as follows: 1. Focus on a distant object. 2. Pivot the two halves of your binocular farther or closer apart until you can see a single unobstructed, circular field of view. Make sure to focus on a distant object when you do this because when you focus on a close object you always see two slightly overlapping circular fields. Your binocular may have a scale on the top, between the eyepieces, to help you remember this setting.
