I don't know how to post a link.These were not spot diagrams regarding optical quality or star testing, but the spiderweb like diagrams indicating how the image stabilisation reacts. There are different shapes to each binocular model shown, although I don't know if these are actually significant and relevant differences. The 8 x 25 shows the strangest pattern, which may reflect the different tilting mechanism compared with variable prisms.When I tested a 2014 model 8×25 it displayed very rapid but very small amplitude corrections, which I initially didn't see, but which are visible if you look very carefully. The tilting mechanism in my opinion made the 8×25 new version much more capable than the older version, which I think used variable prisms.That is why I wondered if they could actually use this tilting mechanism with the 10×30, but they have retained the variable prisms. There may be size or weight limitations on this tilting mechanism. I don't know if this tilting mechanism is used in photographic lenses.Perhaps you could tell me what you think of those spiderweb like patterns and what they mean. Perhaps there is a translation from the Japanese available.</blockquote>
