This depends on where you are geographically located. If you are in Australia there are only one or two people who can help. If you are in the USA the same applies. Try typing in "binocular repairs" into Google and see what pops up. For example in Australia you will find "The Binocular & Telescope Shop" and "York Optical" pop up.

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

How to get my single image back?


Although It may not appear to have prisms because of the sleek barrels, they do infact have roof prisms in them. Most likely one of the prisms is out of position. Bushnell typically has a great warranty so contacting them to have them repair it would be my recommendation. Here is there service group link: Bushnell Repair Services. If you need additional guidance do not hesitate to contact the folks at RCS Optics

I was given a pair of 10X42 powerview FOV293FT the Prisms seem to have shifted can they be repaired and would this be cost efective Ian South Africa


If there has not been a major blow, it is in most cases straightforward to align that double image.
Begin by looking if any of the eyepieces or front tubes are jammed, if so they need to be straightened or replaced.
Another problem is if something rattles, and if you notice that it affects the double image. It could for example be the prism holders, or the front lens of the eyepieces. If you are lucky it is just the adjustment screws not being properly screwed in, see below, otherwise this problem needs to be taken care of firsthand.
For adjustment of the double image binos come with three more common options. There are in some cases concentric adjustment rings around the front lenses. More frequently on porro binos there are adjustment screws on the prism housing. You find them under the front and rear edges of the rubber fascia. Or with roof prism binos you often adjust the angle of the eyepieces with in that case adjustment screws on their periphery
To adjust you first pull the two tubes apart a little, look then at something with horizontal and vertical lines in the distance, for example a building. The image will look like bino views in a movie film, with two different circular fields of views kissing each other in the middle.
It is easy to see malalignment for horizontal lines as they go from left to right. These are also the most important to adjust. For vertical lines you need to scan left and right and see if the image jumps sideways. This direction is actually not totally necessary to get perfect, the eyes can slightly adjust for this, but at the price of fatigue.
Be careful and make small adjustments at a time. You should be done in a few minutes.

My nikon 10x50 action binoculars have developed the problem of the left and right lenses not viewing the same image. the left side view is much lower than the right. i don't know if the prism was knocked...


Common problem with binoculars after a knock. One of the prisms has shifted, putting them out of collimation (alignment). If they are very high quality or collectible they might be worth fixing. It is likely to be expensive. I have done a few pair myself, but only when it was uneconomic to have it done professionally (I have ruined a few too).

One eye or the other seems slightly out of focus.


Hi, one of your eyepieces has an twisty eye piece, its printed on the outside + & -, probably the right side? If its the right side you close your left eye and focus with your right, then open both & HEY Presto, you've got vision in both! Thanks Mark

Double vision


I'm assuming you have set the dioptre correctly for your eyes.

Normally this is caused by a collimation error when one (or both) prisms move. This can be by a small amount.

Your going to have to take them in for service/repair to fix this as is not a DIY problem. (Unless of course you have a collimator lying around)

Hi - This called the diopter adjustment which compensates for small differences in focus between the left & right eyes.

See the following web page for adjusting :
