Just for curiosity, are they actually made in Japan? In the website they say that the 10x30 and 12x30 are optically ‘based’ on the petrel model which was (at least in the beginning) made in Japan, but in the pictures I’ve seen for the 10/12x30 it’s clearly written ‘China’ in the body.Good point, different eyepieces might indeed explain the similarity of the FoVs of the 12x and 16x. Btw, according to Kite the APC42mm binos are made in Japan.
I was almost decided to buy the Fujinon ts-x 1440, but if these 16x42 are made in Japan their price would be very attractive.
