While 7x binoculars have a small (but significant) following, the market is saturated with 8x and 10x instruments. Accordingly, it's always seemed odd to me that 9x binoculars are something of a rarity (although I know that there are some). A 9x35/36 instrument is surely a happy compromise but there are very few of them and not one of them is made by a top alpha brand. One suggestion I've come across - which I find unconvincing - is that 9 is considered an unlucky number in Japan where many instruments are designed and made. Another suggestion is that 8x and 10x are established niches and few manufacturers are willing to step out of line.
