Why we choose the Fujinon vs other brand IS Binoculars: We had an opportunity to compare the various Canon, Fujinon, Nikon and Bushnell Binoculars stabalized binoculars side by side in one store. The Fujinon 14 x40 have the widest degree of stabalization (5 degrees) the Fujinon 12 x 32 and Nikons have slightly over 3 degrees and the Canon have slightly under 1 degree stabalization. Practically this means that you can have a wider deviation from the axis straight at the object you are viewing and it will be stabalized with the wider stabalization degree. Practical Sailor gave the nod to the Fujinon in their review of stabalized binoculars. The Canon, Nikon and Fujinon are all excellent binoculars, and I have several expensive Canon Image Stabalized telephoto camera lenses which I am very happy with. I am not sure what the differences are, but Fujinon also has some stabilized binoculars which cost in the $5,000 range--must be something really super, and I suspect way beyond what my worn out eyes can appreciate!
