Yasuhara, the Japanese company that brought us the Nanoha macro lens for Micro Four Thirds, has just introduced a set of AF-coupled macro extension tubes for Micro Four Thirds and Sony NEX. The tubes sport electrical contacts so that autofocus and aperture functionality are retained, and come in a set of one 10mm and one 16mm tube. On the US market, each set (NEX and MFT) will be available for US-$ 159.
Technically, we assume the Yasuhara tubes to be similar to the ones that Kenko introduced early last year. While both the Kenko and the Yasuhara tubes come in a set of 10mm and 16mm tubes, the Yasuhara tubes appear to be the more affordable solution. Whether or not they’re of the same quality as those from Kenko (which we reviewed here) will be seen once we receive review units.
