Hello, Jim, Chad, Harold and Valerie. I'm a Conquest user as well, and I also have a friend who heads-up the Zeiss program for birding optics in the U.S. I asked him for guidance with regard to the issues you reported below. Here is what he said:
Valerie and Harold, he suggests you do the same--complete the repair inquiry form and send it to the address at the link above. Typically when they are not working as she is describing, the cup needs a little extra torque to have it sit in the bino housing and not come up as the extendable part rotates up and down. It is easy but some folks understandably do not want to over tighten it. They are designed to come off for washing, cleaning etc. in the event debris, sand, etc. gets down into the mechanics.
He says that it is important in all cases that you make sure you have completed the Warranty Registration.
I hope this helps!

Subject: Re: Binocular Problem
Interesting; I also have Zeiss Conquest binoculars. While I haven’t had the diopter issue, I have had to replace an eyecup, and the replacement eyecup has not performed as it’s supposed to; it will not extend to the farthest position without the whole eyecup unscrewing. If you do a search, you’ll see that is a common issue, and I wasn’t terribly impressed with the customer service I got, so I hope you will have better luck. (I did drop the binoculars so I screwed up the original eyecup myself.)
In case anyone is considering these binoculars, I’ll add some more information. While the optics are phenomenal, the lens cap is awful…it fits very poorly and is "held on" by a flimsy cord. Customer service sent me a second cap which fit no better than the first one, so I just bought a pair of generic caps.
Last thing: I wanted a pair of compact binoculars (8 x 32) and got the Nikon Monarch M7. These are superb! I first bought the cheaper Celestron Trailseeker and sent them back the next day—super stiff focusing wheel.
Happy birding,
Valerie

>> I have a pair of Conquest as well. I’ve had mine for a similar amount of time and haven’t had that issue. On the other hand I can say when I had issues with the eyecups, I called Zeiss and their customer support was great. The gentlemen tried to talk me through a self repair over the phone and when that didn’t work he mailed me new eyecups for free. No receipt or anything else was asked for. He took my address and I got them about a week later. Mailing them in for repair is obviously more involved but after my experience I would feel confident about them doing right by their customers one way or another. Definitely give them a call. Hope you get your issue resolved.

Then, when I look at something that's at a significantly different distance from the distance I used for adjusting, after focusing, I find that my vision is out of sync for my two eyes. It's as if the focusing knob isn't functioning properly to keep the two eyes in sync.
