Hi, the lower star ratings indicate that when the focus is set, then the zoom feature is used the glasses need to be refocused. Is that a defect or is that the design? Thank you for your time. BHolmes

Hi Bart: Yes, these binoculars will defocus when you zoom in, especially going to full zoom. It is part of the design. Some binoculars are advertised as constant focus regardless of the X power you are using, however, I am not aware any of these get high ratings for image quality. These Nikons will give you very good image quality but to get that requires an optical design that doesn't include constant focus. I bought these because I wanted the zoom feature and good image quality. In order to get anything significantly better would mean spending $2000 or more.-Mark, PC35 PhotoLab Hi Bart: Yes, these binoculars will defocus when you zoom in, especially going to full zoom.

It is true that they need to be re-focused if focused with zoom setting. However, I am not sure that is a manufacture defect or just the design. They work fine for me. But then again, I don't mind refocusing for the price I paid for the set of binoculars.

it may not be a issue of focus it could be an issue of filters, to view planets yes you will need good lenes and a barlow adapter but there are color filters that enhance what you are looking at, I suggest you search the web for Planetary filters to see which filter is best for the planet(s) you are trying to view.

It is good quality. I had a problem with it when I first bought it, the problem was that it was only clear at 2x and was fuzzy at anything above 2x. I found and fixed that problem...I took off the bottom lens(the one that is farthest from your eye) and had to screw the black inner ring (that is connected to the glass) down deeper into the scope. The glass was just not screwed down far enough from the front glass. Bottom line: It's like a telescope or binocs or microscope, the lenses (glass) at front and rear have to be the correct distance from each other for a crisp/clear view. It's well made. If you get it and it's fuzzy, just play with the lens position It is good quality.

FWIW, mine is usable only for general composition purposes. Forget about focusing, or even really seeing what you're shooting with it. I actually put mine away the day it arrived from amazon and didn't touch it again for probably a year, and figured I should have simply returned it. But since then I've come to terms with what it can and can't do, and put it on in the sunshine when I can't see the screen, and use it just for positioning large objects in the composition.

It may also be the case that you are looking at used or refurbished lenses. I bought one used, it is like new and an excellent lens for low price. Best regards

There is no focus. Only adjustment is for the width of your eyes. That's it. They work fine for me. Maybe you need to use your glasses.

I remove my glasses when I use these binoculars. I tried looking thru them with my glasses on...it clearly reduces the FOV because you cannot get your eyes as close to the lenses as you can without glasses on. I suspect that would be the same issue you would find with any binoculars.

I think you are right here. I don't believe it is a lens problem as I have see this problem across a couple of lens. I did two things that seem to make a different, the first was I completely reset all the camera setting and second thing I did was up grade the camera fireware from version 1.0. 4. to version 1.0. 9. This seems to have made a difference.

My EOS-1Ds Mark III arrived about two weeks ago around the first of Dec. Certainly there are no focus problems on any lens I've tried, and I have 8 or 10. In fact, one can "tweak" the focus for each lens. I've not seen the need for this rather technical step, however, and should I, then I'll do it professionally with correct charts, lighting and so on. It can be redone, though, so any errors can be corrected.

No its not working. there is no focus at all. so i cant see anything. Can i return it ?

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

I think there can be many reasons for this - could be sharp in the small viewer but not so sharp when expanded -- could be due to camera shake, too slow shutter speed, or possibly the camera didn't grab the object you wanted to be the main focus. I will place the subject in the middle of the screen and half depress the button -- then move the camera to the composition I want, which holds the focus where I intended. It may not be the best autofocus on the market. But on the whole it's a one of a kind camera, a keeper for sure.

Send it back immediately- Amazon is great about returns. Mine is as solid as a brick and is the best built lens I own. You will see when you get another one back.!

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

i know you asked this a while ago, but i think that's unfortunately just the way it's made. ours is fairly blurry & requires a bit of explanation regarding what the shot was when he shows it off. he loves it though, only thing he really seems to be disappointed about is the lack of zoom *grin*

When we first got ours we had the same problem with clarity and had searched all through the menu options with the blurry image trying to find it. The plastic part around the lens is what you use to focus the image. The first time it felt like that wouldn't move but if you keep at it gently it will work and then you won't have any problems moving forward. Once you fix the clarity you can read the menu better to adjust the image size. Good luck.

My experience is that it adjusts the focal length and this the magnification increased, but you must move the subject closer or farther from the end. You may have to move the small object into the window if it comes into focus. Depth of field gets very tight at higher mag.
