Delivers Optical Perfection, Whether Day or Night

This particular model offers an 8x magnification and a 40mm objective lens diameter. As it sounds, the 8x magnification produces an image that appears as if the user were eight 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 5mm, which for 8x40 binoculars 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 is a wide 143 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation.

Versatile and Bright, these Binos Will Have You Reaching for the Stars

Offering an 8x magnification to bring faraway points of interest that much closer plus a 40mm objective lens diameter, the Olympus 8x40 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 8x40 DPS I model further sports a 12mm eye relief for extra comfort, plus diopter adjustment for comfortable viewing without glasses.

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.

I have been birdwatching for more than 40 years and my well used 25 year old Swift Audubon 8x42 binos finally gave up when the focus ring became detached. I regarded these as perfect binos as they were sharp and clear at all times despite having almost daily, certainly weekly, use over that time. I did a lot of research on ebay and amazon and intially thought I would go for a used pair of Swifts on ebay, but each one went for over £100 for a used pair. After reading the reports on the Olympus 8x40 dpsi binoculars I decided £38 for a pair to be couriered to my home in spain was a risk worth taking. I`m pleased I made that decision. They are as crisp and clear as my old Swifts, rugged yet lighter. I have replaced the neckstrap provided with a wider one for comfort. The binos come with a soft but useful bag.If you are similarly researching which binos to go for, don`t reject these because of the low price. I thoroughly recommend these Olympus 8x40`s.

The binoculars were a gift for my husband. He was thrilled with them! They are compact yet powerful enough for bird spotting in our garden and nearby area.

I did not read any reviews before I went out shopping for a new pair of Binos. I wanted to make up my own mind.

I visited 6 different shops and tested about 10 different makes. From the cheapest to Leica and Zeiss. I was prepared to pay anything as long as the quality and the image produced could justify it.

The most disappointing was the Bushnells. I tried 4 diffent pairs in the fist shop and the first two produced double vision. the other two could not focus properly. It was the cheapest part of their range but after 4 tries I lost confidence in their quality and wrote them off on the spot.
I tried a few other makes in the same price range but was not impressed. In another shop I tried the Nikon range and they were realy good, and at about 140 GBP a reasonable buy.

Comparing Nikon to Leica and Zeiss there were some difference in quality but only marginally. The sharpness was more or less the same but the periphery of the viewing field of the expensive German makes had some advantages.

The last of the 6 shops I visited had the Olympus 8x40 DPSI and I tested one on mid and long distances. The image quality was more or less the same as the Nikon ones. Image distortion at the fringe of the viewing field was may be slightly better on the Nikon but only by a very small margin. The Olympus cost 90 GBP compared to the Nikon at 140GBP.
I decided to think about it and did not buy anything until i returned home and found the Olympus at the Amazon site at just over 40GBP and then decided to take the plunge.

I have now had them for several days and had a chance to test them properly.
Pros:
1. The images produced are very sharp
2. The viewing field is over 8 degrees and makes it easy to find moving objects.
3.

I received a pair of Olympus 8x40 DPSI bins just 2 days ago. They feel solid and well built. Weight's not a problem. In bright conditions the sharpness, brightness and clarity of image is amazing, and still excellent in low light. Field of view is very good. Chromatic aberration is none existent. There wasn't even a hint of colour fringing on a Mute Swan in poor light. I have owned Leica 10x42's in the past, and I'm sure these are just as sharp, definitely brighter, and with the plus of the porro 3D effect.
Now that is my view without glasses. They aren't as easy to use with glasses (just put them in your pocket).
I don't know how much of a problem fogging will be in colder weather, and as they aren't waterproof I won't use them in the rain.
They do need a better strap, but for the price these bins are an absolute steal. Outstanding.

I'd put these binoculars up there with the Zeiss and leica's I've tried. They are a twentieth of the price and offer indistinguishable quality in real world situations. Really don't know how they do it for the price.
Olympus have a great optical tradition and it's reflected in these binoculars. Value for money just doesn't get any better. We're talking about pocket money prices for world class optics.

I have a collection of binoculars amassed over the years and kept in three separate locations including the car. These range from 7X to 10-22X zoom including Nikon, Hilkinson, Canon, Tasco, Bushnell etc. While, hitherto, the 8X42 Wide Angle Bushnell had been my favourite for general travel purposes that changed instantly on receipt of these Olympus 8X40 binoculars which I regard as outstanding and with crystal clear optics. Am I alone in thinking that the quality of optics has improved greatly over the past thirty years?

In my view these binoculars would still be a bargain at ten times the price. Do not hesitate to buy!

We live on a cliff top and wanted some binoculars for looking at the ships going by or seabirds. We even get the occasional seal or dolphin in the Summer. These binoculars were a reasonable price, I didn't want anything too expensive but wanted something half-decent that would let us see what we wanted to see without spending £300. These are good quality, they feel solid but are not too heavy to hold, they come with a nice padded case and I like the focus on them, it's crisp and clear. After reading all the reviews, I felt these were a good choice for us and fortunately, I made the right choice. Highly recommended.
