Can a zoom lever on a pair of binoculars be repaired

Unfortunately the rubberised coatings on some binoculars (and, indeed, the focusing and zoom rings on some camera lenses) go like that in non-optimum storage conditions - i.e warm moist areas, such as a kitchen cupboard. I'm afraid I know of no way of curing this - you may need to take them to a repair facility and ask their advice.

Your binoculars either have a bent or broken yoke assembly (the bit which carries the eyepieces) .

The repair involves replacing the entire yoke assembly: the part is expensive in comparison to the retail cost of a new pair of binoculars and with labour charges on top is not usually a cost-effective repair except on really high end models at prices far higher than yours which can be completely replaced for under GBP£90. The yoke cannot be repaired:if it's broken then it will have bent first, and if it''s just bent then it usually breaks when trying to unbend it. If you do manage to unbend it, then it's usually fatally weakened and almost never accurate anyway.

I hope you manage to use this information to fix your binoculars or at least that it assists you to choose your next course of action. Please take a moment to rate the free answer I have provided for you and any testimonial which you might wish to add is always welcome!

Dear sir,

this happens when the clearance for the lense mechanism to open and close is being insufficient due to -small bits of sand or lint that may become get trapped in the mechanism which is commom while taking photos in open dust spaces.

It is advised to take the camera to a camera repair shop and have it disassembled and cleaned,if delayed the problem gets complicated....


thank you ..take care

Send them back to Nikon. The first pair i had did it twice, then they sent me a brand new pair. Here a year later with new pair the eyecup pieces that turn in and out already have cracks in them again.

You can't.

Tasco optical products are very cheaply made items, usually bought direct from whichever factory already makes the same or a similar model and then Tasco have their badges and packaging added.

They are consumer grade models which are not designed with longevity or repairs in mind; they're worth little when new and almost without value as used items.

The only repairs which can be done are by Tasco themselves whilst their products are under warranty. Except for the most minor of repairs, a warranty claim will simply involve exchanging the faulty item for a new one as any labour expended in repairs will often cost Tasco more than the wholesale price of a new unit.

Your only fixes are to live with the missing eyecup; to visit a binocular repair shop (not exactly commonplace) and see if you can buy an eyecup which can be adapted by yourself to fit; or to replace yours with another pair. You'll usually find that there are plenty for free on your local FreeCycle or Freegle group but they'll often have the even worse fault of a broken eyepiece yoke. But the price is right so it doesn't really matter if you have to collect five or six pairs before getting a good pair...

With all due respect, 7x-15x35 are going to be optically atrocious, so replacing your current pair is not a bad idea.

If the zoom lever is not working then I would recommend buying a new pair without a zooming mechanism. Zoom binoculars are more trouble than they are worth. Sorry!

Best to take this to a repair agent as there are inherent problems in trying to fix these by yourself. Main one being zoom registration between both sides of the binocular.

I'm sorry to say this. Not much. Maybe 30 dollars US on a good day on the auction site if the binoculars are in great condition. Zoom binoculars are not known for their quality optics. Jason binoculars have a small collectable quality in a niche market for old Japanese optics. Just to have not for their optics. Non zoom older Jasons are worth a small amount more.

Try cleaning the connectors with a scotchbrite pad, then blow it out with a dustblaster
