G'day Visualopsins,
Yes I had looked on the site and it was all I found. For some reason there is no data on just this lens out of all the lenses they marketed. I have a suspicion it might be a Tessar or even Planar design, the front element is set way back in the body of the lens.
It came with a MAB auto bellows I picked up, with a 2.5 dioptre close up lens on the front! |
