The Papilio, which comes in two versions – 6.5×21 and 8.5×21 – is special, or even unique, in a number of ways. First, when taking it in to your hands, it’s much smaller than you would expect from seeing it on pictures or in catalogues. Second, it’s design is that of reverse porro, with both objective lenses close together. Third, a special mechanism allows it to focus as close as 50cm, making it a preferred instrument for people observing insects, spiders and the like. This mechanism causes the axes of the objective lenses to increasingly converge, the closer you focus – very nice! But the Papilio is also in use for some birding activities. It is definitely not one of the expensive binoculars, but it features decent optics and mechanics, is easy to handle and has even a screwhole to mount it on a tripod or monopod. Good central and – for the price – very acceptable peripheral sharpness, aceptable brightness and good CA correction, but a slight pinkish tint of the image.
