Hi all. I have a Horseman 980 which I love dearly. It just returned from Nippon Photo Clinic in NY where they did a spectacular overhaul. Anyway, I enjoy photographing with this camera very much, especially for my homebrew lens projects. Something I've been thinking about for a long while is getting the fastest lens that will fit the camera. I'm looking for something in the f2 to f2.5 range if it exists. I've been making some lenses using found elements and I've got a few that are f2 but these have specific characteristics that come along with being an optic not intended to be used the way I use them. I would be interested in knowing if there is a lens that will fit my 6x9 tech camera. I guess the equivalent of the Aero Ektar for 6x9. So does anyone know the fastest lens that will work? Thank you for your help!
