SOURCE: I lost one of the rubber eye reliefs from my Nikon

I have had the same problem with a Nikon binocular. Contact Nikons service center in your country, they will order one in. If they don't have it in stock it takes about 6 to 8 weeks.

If you have a very old model compact try asking in forums such as Cloudy Nights.

SOURCE: need to realign the optics for Binoculars

You can't. It needs to be done professionally.

I imagine that you are now finding that whatever you do, you cannot get both eyepieces to focus. Most likely, the carrier yoke for the eyepieces has bent or broken: it's by far the biggest single cause of binocular failure.

If it's bent then straightening it is rarely accurate and usually results in the yoke breaking or leaves it severely weakened and ready to break. If it's broken, the physical loads across such a tiny contact area making gluing impractical. Even in the rare cases where it can be done all that it results in is a yoke which is back in one piece but which is now bent.

In most cases, the cost of repair exceeds the cost of replacing with new, but your binoculars are fairly expensive so that's most unlikely to be the case. But if you want them to work again like a £500+ pair of binoculars then you need to send them for professional repair. If you do it any other way then you may as well throw them away and buy a £15 pair of Bresser Meade 10x50's from LIDL (excellent binos for the price and comparable to many £100 models, but not in the same league as yours when fully functional).

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

In just a little rain the outer lense fogs up bad enough that I cannot see through them at all.


This is normal enough.. Your binoculars don't have an anti-fog coating on them.
Bushnell do a spray on anti fog if you want to give it a try. Any good Bushnell stockist should be able to get it for you..

Call tech support! That's why these people get paid. Sites like this wouldn't need to exist if they did their jobs correctly!
