    Hard to imagine the ground glass too dim with a 1.9 lens! What is the focal length? Sounds like it could be a promising lens. I'll watch the classifieds if you decide to sell the holders, they could be handy.

    It must be an f9

    I don't think anybody ever made an f/1.9 lens for large format. It would be enormous. It must be an f9, sometimes written as 1:9.

    George, Dallmeyer made the f/2.9 Pentac in many focal lengths. The longest is 8". You're responding to a typo.

    Dallmeyer made their Super Six at f/1.9 in focal lengths up to 6", f/2.0 at 8". I've had a 6"/1.9 Super Six, sold it long ago. Too valuable to keep in the closet. Super Sixes cover their focal lengths so the 6" and 8" were normal lenses for 4x5 and 5x7 respectively. The 8 incher might work on a 4x5 Graflex.
