This is a younger brother of F3.9ED family. Looks very nice finish! Personally I like that. A main tube is 120mm long. So you can guess how short the scope is.


350mm f.l. / 55mm image circle

330mm long / 3.8kg including a motor unit


Fixed dew shield.


90FL F3.9ED as well as 107FL’s will publicly show up at NEAF first time.

  1. Hey Ted,

    is that for sale yet? How about pricing of components as the kit shown mounted in the 3rd photo. As you know, I already have the 90FL lens cell.

    Thanks,Ted, and best regards to Mia,
