Quote:as for the ultra's they are a very good binocular for 350.00,built solid and no worry about going out of collimation.very sharp optics and contrast. sharp out to about 80% of the field,bright as the fujinons,but the fujinons have the better edge sharpness,eye relief is a little short if you have to wear eyeglasses.little on the heavy side,they are the closest thing to the fujinons so far coming out of china and at about half the price...

Quote:joe i don't think you would have any vignetting with the 20mm, i use 24mms with a 70 degree field and have no vignetting, the bt80s and the bt100s use very large prisms.you could send them and i can try them out if you like. regards john
