Optical Perfection, Day or Night

This particular zoom model offers an 8x to 16x magnification and a 40mm objective lens diameter. As it sounds, up to 16x magnification produces an image that appears as if the user were 16 times closer to their subject, while the objective lens diameter refers to how much light can be gathered to form that image. While for daytime use a lens diameter of 21 to 25mm is useful, for night-time viewing something between 35 to 50mm is recommended. Therefore the 40mm specification here indicates excellent suitability for low light visualisation.

Also worth considering for low light work is the exit pupil. Here that is 5.0 to 2.5mm, which for 8x40 binoculars, for example, is arrived at via 40 divided by 8 = 5 exit pupil in mm, so beyond the 2-3mm which is generally thought of as being suitable for daylight use. Another thing to take into account is the field of view, which here, due to the zoom capability, is 87-59 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation. Closest focusing distance is 10 metres.

Versatile and Bright, these Binos Will Place Nature in the Palm of your Hand

Offering an 8x to 16x zoom magnification to bring faraway points of interest that much closer plus a 40mm objective lens diameter, the Olympus 8-16x40 DPS I Binoculars incorporate fully coated lenses to deliver maximum image brightness, visual impact and image defining contrast.

Fast and easy focusing is provided courtesy of a large, centrally placed knob. The 8-16x40 DPS I model further sports a 10-12mm eye relief for extra comfort, plus diopter adjustment for comfortable viewing without glasses.

Engineered for Excellence, Built to Last

Boasting a tactile and ergonomic design and weighing a solid feel 790g, the Olympus 8-16x40 DPS I measurements are a manageable 182x152x58mm, while the package includes a neck strap, case and protective lens covers.

In summary, with a lens configuration of 6 elements in 4 groups, and a 10-12mm eye relief, the field of view at 1000m is 143m. The actual field of view is 5.0° to 3.4° while the apparent angle of view is 40° to 54.4°.

These are also binoculars that will repay your original investment with years of good service. A case in point: a 25-year warranty is included with any purchase.

The clarity of this product was nothing short of stunning. On 8x magnification the image was pin sharp and clear. When using 16x magnification some support is required for a steady image but this is not a negative comment. The focusing wheel is very responsive and easy to use. I would thoroughly recommend this product, especially for wildlife enthusiasts.

I was looking for a compromise between great optics (usually found with 50 mm lenses) and small size. For me, these offer the best of both worlds - small enough to take on a hike, but with a good clear image. Even with 16x zoom, it is possible to have a steady image. I use mine on 16x zoom most of the time, so I'd be happy not to have the zoom - maybe it will come in useful one day. My only complaint (and a very small one it is) is that the lens covers are not attached to the binoculars, so one has to be careful not to loose them. Highly recommended.

I've owned a pair of these for about 18 months and have used them thoroughly in that time. I'm a member of the RSPB, WWT and my local Wildlife Trust, and I regularly take these binoculars birdwatching. I bought them to get back into birdwatching after 20 years away from the hobby. They seemed good value for a brand I trusted and the zoom sounded like a great idea - 8x magnification for scanning around and then up to 16x for more detail was my theory. However, to be honest, I now wish I'd done a lot more research before making a purchase.

At the lower magnifications(8x to 10x) the image is bright and clear. There is also a good depth of field meaning minimal refocusing even when scanning across a lake or open field. However, the higher you go the more the performance drops off. At 16x magnification the image is noticeably darker and quite fuzzy. Also, at 16x the depth of field is extremely shallow which means it is difficult to attain perfect focus and you are constantly having to refocus if the point you wish to view changes slightly. You will also need VERY steady hands to use them at 16x - even with both elbows planted on a flat surface the image can be a bit shaky.

A minor bugbear is that when you zoom in or out on an object, it doesn't stay in focus and you need to refocus each time, so you might miss some action or lose track of a bird in the process. After a while though, you get used to how much you need to adjust focus and in which direction to minimise viewing disruption, but it will still take a couple of seconds to get sharp focus back.

At 8x the field of view is 5°, which is OK, but could be better. The field of view is basically the width of the image you see through the lenses.

Yes, I know, good binoculars are expensive. And I also know that designing zoom binoculars pose so many technical challenges that most top brands don’t even try.

But the good reviews of these binoculars made me decide to try them. Unfortunately I think they are not worth the (admittedly low) price.

So what’s bad? Optical quality is just average, image seems soft and aberrations, namely CA, are not particularly well avoided; The limited field of view imposed by the zoom design is really annoying (yes, I know one can read about it in the specifications but reading is one thing, seeing is another…); The bridge between the two eyepieces isn’t sturdy enough (although I’ve seen worse in this price range) allowing the eyepieces position to change when one presses the binoculars against the face causing not only defocus problems but also focus shift between the two tubes; The eyecups are not comfortable, non-adjustable and non-retractable or foldable (for use with glasses) and they don’t seem to have the right size for the eye relief value of these binoculars so they don’t do a good job of blocking extraneous light sources; The neck strap is very thin, but that’s normal at this price point; Worse of all (to me) these binoculars suffer from a strong tendency to cause “blackout” (my wife complains about the same so it’s not just a problem of my face shape), probably because of the bad design of the eyecups, making their use extremely uncomfortable except for brief periods of time.

Isn’t there anything good? Sure there is, I’m giving them two stars, not one… These binoculars are reasonably light and small for 16x40; They are inexpensive (although I’m not convinced they are worth the price); The exterior rubber like material feels good, even in cold weather; They are reasonably well balanced; Collimation seems reasonably good, particularly for zoom binoculars; The tripod connection thread looks good and the screw-on cover is well made.

These Binoculars are an absolute bargain at a knockdown price!
These bins came in really good time and I immediately went out for a spot of birdwatching with them,the image they give is really excellent and Though at first I did find the zoom lever a little stiff, that soon settled down( just as I was considering a little WD40) Zooming up to 16X I really could not see any huge amount of dimming and it is well possible to hold the bins steady enough for a good view.Though holding the bins steady for any length of time would be an issue and you would need some sort of prop to steady against.
Now the bad news,within two hrs a hair or something similar fell across the right lens and ruined the view through them,I cannot find the heart to remove a star for this as the binoculars are so good!I then e-mailed the brilliant return service at Amazon who e-mailed me a pre paid printable Royal Mail address form,As the company I ordered them from had none left in stock,I was forced to take a refund.
I had kept the original packaging so I packed it all away and posted it on the Tuesday,On Wednesday evening I received an e-mail saying they were in posession of the return and on Thursday morning another mail saying my money had been refunded! Brilliant service so I immediately ordered another pair from a different seller £2.70 more expensive but they are well worth the money!
I have just received my relacement bins and they are really terrific! I am so pleased with them.
