Are My Binoculars Defective?
Question by zmneuro: Are My Binoculars Defective?
Got Zeiss Conquest 12x45 hunting binoculars off ebay. The binos look new, but the image in the left tube is way too fuzzy, out of focus. Just like if I was wearing reading glasses with huge diopter. The right one is fine. Neither focus, nor diopter adjustment do improve image in the left tube. The image looks same for both eyes (if I look with one eye at a time). So when I look through both tubes and align them together, I still can see distant objects but I have discomfort, clearly because of out-of focus or whatever in left tube. Called Zeiss, left a message but no reply. What can be wrong? Is there any way to fix this? Thank you

Sure sounds like a defective pair, what were they listed as? New or Used? What is the sellers rating?
Give your answer to this question below!
Nikon Premier LX-L 10x25 Binoculars
- 10x magnification with a 282-foot field of view at 1,000 yards
- 25mm objective lens diameter
- Weighs 10.5 ounces
- Lightweight magnesium alloy construction
- 100 percent waterproof and fogproof
Traditionally, a 10x25 binocular is perfectly suited for theater and stadium use. Extraordinarily compact, it provides ample magnification with a reduced field of view so you can Focus on Character and action details. Of course, it's really lightweight and easy to carry around. The Nikon Premier LX offers superior optics and all-weather protection so you can use it as a very compact birding and field scope. It's especially useful when travelling because it doesn't occupy lots of luggage space - great for travelling light. It includes a leather case and Lens protectors. Superior optics, sharp focus, and long-eye relief (for eyeglass wearers) contribute to help make the Premier LX a top performer for theater and sports viewing that's more than effective in other applications too.

Use the center focus thingy to focus the view in the left eye….and then use the diopter adjust eyepiece on the right to adjust that one.

Have you tried twisting the eyepiece adjustments?
If you didn’t know these adjust, that could be your problem.
Being as they are used, Something could have happened to them. You might unscrew the left eyepiece and check to see if someone stuck their finger in there and smudged it up on the inside, to. If these suggestions don’t help, Keep calling Zeiss, because you need factory service.

Sounds like you have a defective pair. If the binoculars are new, you should be able to return them to Zeiss for warranty repair.
If they were not purchased as new, and you purchased them just recently off eBay, you have recourse thru either the seller (for a refund), or, if that goes nowhere, contact eBay (or PayPal if you used them) to file an “item not as described” complaint.
Good luck.

if it’s blurry and the focas moves but dosnt focas, the lense could be smudged, try a lense cloth and some windex and clean out all the lenses, even the inside ones.
it wont hurt the eye glasses even if that dosnt work.

All binoculars have something called a diopter adjustment that is used to compensate for the differences in the focal length of the individual eyes. Depending on the particular binos, the adjustment can be located in different places. On less expensive binos, it is on the right eye piece. You make the adjustment by focusing the left eye on an object and then closing the left eye and turning the adjustment on the right eye until the right image is in focus. Then you note the setting that you made. There should be a scale on the right eye piece. On more expensive binos, which these are, the adjustment is locking and the lock has to first be disengaged. Also on the more expensive binos it may not be located on the eyepiece but on the center focus nob itsself. I do not know exactly where it might be on the Zeiss binos, but it should be one of those 2 places. On the locking diopter, you normally have to pull up to disengage the lock then turn it, then push down to lock it in place.
