When Leica updated this Trinovid 10×42 by bringing out the Trinovid 10×42 “HD” version, they did the opposite of what they had done with the upgrade of the 8×42 version: they widened the field of view (in the 8×42, they made it smaller). But this older version still has a decent FOV, and it is a very nice upper class binocular, with impeccable mechanics and a very good optical performance, that stands well in the line of the renowned “Trinovid” tradition which goes back well into the 1960s.
