Thank you for the two links.From what I can make out, the larger more expensive binoculars have triplet objectives, and their doublet field flatteners have an air space and are not cemented, whereas the present and recent 10×30 and 12×36 seem to have doublet objectives and cemented doublet field flatteners.However, as I said before different links show different eyepieces.Unfortunately, my Japanese is nonexistant, but I would like to know what the spot diagrams mean and show regarding the image stabilisation. They have different shapes, but maybe they only show the limits of travel of the variable prisms and the tilting mechanism of the 8×25.In your review I think that the new and old 10×30s in the photograph are labelled the wrong way round. Unfortunately I haven't visited Italy in many years.Thank you again for your reviews of these and many other binoculars.</blockquote>
