Customer Comments

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 initially 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

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.
1. The images produced are very sharp
2. The viewing field is over 8 degrees and makes it easy to find moving objects.
3. The focusing is very easy, from about 80 meters to 5 km ++ you hardly need to move the focus dial more than a few mm and it is very smooth. In fact the debth of focusing is very high - that is why some comments that it is 3d - that just means that the focus in front of the object and behind it is also in focus.
4 The distortion in the periphery is minimal and with the large wide viewing angle it has no practical downside.
5. It is very well build and sits comfortably in your hand.


The light sensitivity is more and less the same a the naked eye. I have had a 7x50 bino and there you see more than the naked eye at night when the moon is out. The Olympus binos reproduce no advantage over the naked eye or may be just a few % more. It is therefore not recommended for night use.

1. It does not fit in you pocket. It is a mid seized Bino but then again not too heavy.
2. It is not waterproof, so if you live in a damp and humid climate consider a Nikon (well only if you consider using it in pissing down rain or for nautical purposes - I do personally not- but for longer hiking trips it is an issue in the UK)
3. The neck strap is by some considered too thin - I actually do not mind because the weight is just over 700 g but I see the point.

Conclusion. This is by far the best buy I have tested. Super sharp, relatively light, great viewing field. Ideal for general purposes, bird watching, horse racing and the like, . In fact it is a steal at that price. Thanks to Amazon for delivering it as promptly as stated on their web site.
