Remarks:

Despite some positive reviews, the 12×60 HB seems never to have been a great success in the market like Fujinon’s FMT series of binoculars. Featuring good optics, built like a tank and equipped with 60mm objectives which provide more light than in the more common 12×50 configuration,  maybe it was it’s high weight that kept users from buying it. In addition, the field of view is okay but not on par with many other 12x binoculars, CA appears a bit too prominent, and the recessed central focus wheel appears quite shock-protected, but is hard to handle with gloves or mittens. The 12×60 HB can still be found at some shops and on the internet, but is now out of production.
