Remarks:

For some years, Vixen produced a series of four large observation binoculars under the label “ARK”: 12×80, 16×80, 20×80 and 30×80 (Opticron used to sell the same instruments under their own name). In terms of price and quality of optics, they ranged at the upper end of their market, but Vixen’s quality control at the time seems not to have prevented a number of these binoculars needing re-collimation jobs and the like. Reviews by users often concluded that the 20×80 model was the best, performance-wise most balanced of the series. Compact build was a distinct plus of these binoculars, but it is therefore no suprise that the model with 30x magnification would have needed a larger body and produced a sub-optimal image with limited contrast and some chromatic aberration and showed actually less detail than the 20x model. Vixen stopped producing them in or around 2016.
