These Olympus 10-30×25 Zoom PC I Binoculars are in used though excellent condition.
I cannot find a set of these anywhere for less than 85 including EBay and Amazon.
These binoculars are all the quality that you would expect from a high end manufacturer such as Olympus. The build quality is superb as is the user experience.
These binoculars offer a 10x to 30x magnification and a 25mm objective lens diameter. 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.
Note I will only post within UK .
