Fujinon 70mm, Mirakel, Sans Streiffe 999 ====================================== Subject: New (?) Fujinon 70 mm models Fujinon has an economy model of their 10 x 70, 16 x 70, binoculars. The FMT-SX models are the old standard, flat image plane... enables observation of the marginal area of a visual field, sharper, more true to life colors, and minimize distortions and astigmatism; also every lens and prism surface is coated with a special new EBC process.

The weight is 130 grams. The glass has apparently Porro I prisms but I have not opened it. On the upper left the manufacturers name is given - the letters
