While great as a general use pair of binos, they excel when utilised for bird watching, if added to your kit bag when camping and hiking, plus are superb for use at sports events and when travelling.

Delivers Optical Perfection, Day or Night
This particular zoom model offers a 10x to 30x magnification and a 25mm objective lens diameter. As it sounds, up to 30x magnification produces an image that appears as if the user were 30 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 ideal.
Also worth considering for low light work is the exit pupil. Here that is 2.5 to 0.8 mm, which for 10x25 binoculars, for example, is arrived at via 25 divided by 10 = 2.5 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 56-33 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 five metres.

But it's fiddly and not convenient in a hurry, and even then you have to get the position to the eye unusually exact compared to other binoculars.
The result has been a fairly expensive present that my wife hardly uses.
They were lightweight & may suit others, but just not for me.
POORLY MANUFACTURED FOR SUCH A WELL RESPECTED COMPANY SUCH AS OLYMPUS , GLAD I WENT FOR PRAKTIKA 2 1/2 DECADES AGO I'LL BE SUPPRISED IF THESE LAST 2 1/2 YEARS .
I have had these for over 5 years now (bought 2008 - reviewed 2014) and whilst I have moved onto bigger and better quality binoculars, I still carry these with me in my camera bag or when out walking.
They are robust, light weight and easy enough to focus. The zoom wheel can be a bit stiff to move with your finger and tends to throw the image around as you are moving it. Though I have to be honest I now find the zoom to be more of a gimmick than a useful option, especially when given the size of the objective. The image at x10 is pretty clear in good light, but as would be expected with 25mm objectives, it can get dark as light levels drop and worse at x30.
Just a few niggling points: The eye caps fit well, but are not attached and though I haven't lost mine, need to be put somewhere safe when off the bino's. There are no front lens protectors, so you need to be careful when storing them. The storage pouch is OK, but due to lack of lens caps, make sure no grit gets in. I don't use the twist up caps for glasses, but if you are likely to use them, they are hard plastic.
Bottom line: Early on I might not have rated them as highly maybe 3 stars, but after 5 years of use, there is no fogging, image is still as good as the day I had them and there is no double image despite the odd drop. so I would give them 4 stars
