The Poseidon is essentially the same as the Polaris except that it does not have the flat field lenses, but instead has the same type of high quality lenses found on other top-of-the-line binoculars. It has the same EBC coating giving it the same 95% outstanding light transmission. It is slightly lighter in weight at 3 lbs. (3.1 lbs with compass). The eye relief is also less at 12mm, which is in the normal range for most binoculars.
