BORG 107FL F3.9ED (B107FLF3.9ED)





The BORG 107FL F3.9ED the 420mm long & 4.3kg. It’s heaviest among current BORG systems. But still much lighter than the competitor’s. 66mm aperture ED, as 2nd objective lens, is set into a tube inside along with other 3 elements. So BORG-proprietary total 6-element advanced petzval optical design. As far as I know, this should be 1st optical design utilizing both fluorite and ED in same optical train.
