The Olympus 10-30x25 Zoom PC I Binoculars: For Sightseeing and Spectator Sport These Stylish and Compact Binos Score Big with a Powerful 30x Zoom

For when portability is as important as optical quality there is the Olympus PC I series of binoculars; aimed at the urban dwelling sports and sightseeing enthusiast, the 10-30x25 Zoom PC I features a sleek, stylish design yet compact dimensions. 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.

These standard porro prism type binos feature a multi-coated lens for maximum image brightness and contrast, high quality optics, plus the added worry-free feature of UV (ultraviolet) protection. Added to the mix are precisely ground prisms and lenses made of brightness-enhancing barium crown glass (Bak-4) to ensure clarity and brightness to the very edge of the field of view.

Peace of mind and years of pleasure are further guaranteed thanks to a 25-year European warranty.

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.

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

Offering a 10x to 30x zoom magnification to bring faraway points of interest that much closer plus a 25mm objective lens diameter, the 10-30x25 Zoom PC I Binoculars incorporate multi 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 10-30x25 Zoom PC I further sports a 15-8mm 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 315g, the 10-30x25 Zoom PC I measurements are a manageable 114x111x48mm, while the package includes a neck strap, case and protective lens covers.

In summary, with a lens configuration of 9 elements in 6 groups, and a 15-8mm eye relief, the field of view at 1000m is 56-33m. The actual field of view is 3.2° to 1.9° while the apparent angle of view is 32° to 57°.

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 purchased these binoculars as a gift for a friend. I already own a similar set, from Olympus (older model but otherwise identical), which are very good. Disappointed to find eye pieces changed to hard plastic with a very samll viewing aperture making it very difficult to centre your eyes properly. Checked by several friends - all experienced the same problem. Useless for wildlife viewing, as by the time you get them sorted, the wildlife will be well gone. Can't believe this passed Olympus customer testing!

    This model is very poor by Olympus standards. Difficult to set eyepieces to proper width and focus. Not recommended for wildlife viewing.

    I decided to purchase these binoculars to go on holiday with as they were quite light in weight and are an established brand. However, I have found that you can't just pick them up and instantly watch that eagle flying by. Very arduous getting them into focus and trying to get the 2 lenses to the right width for your eyes.

    Getting the alignment of the two eyepieces right is hard, and unless it's perfect, you see **nothing** - there's hardly any tolerance in it at all. And neither of us could do it following the instructions. Best way seems to be to position it for one eye, then keeping that eye carefully sighted on something, adjust the position of the other until you get a clear view.

    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.

    These are nice compact binoculars. The clarity is good at normal magnification but when zooming in, it did become very dark. This will be due to only having the 25mm lenses so less light is able to get in. Also, the zoom slider was very stiff & jerky. I don't know whether this would loosen up over time, but I ended up returning these as they weren't really an improvement over the Chinnon RB 25mm zoom binoculars that I already own.
    They were lightweight & may suit others, but just not for me.

    I uploaded some photos in 2009, for some reason Amazon is putting this review (2014) in the same time frame??

    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
